Sectional barges, which are sometimes called “truckable barges” are relatively small, portable barges engineered to be able to navigate and fit into tight spots where regular barges cannot. They connect with each other to create various platform sizes. They are commonly used for marine, dredge, and bridge construction projects. Sectional barges are easy to stack onto 18-wheelers for simplified transport. Made of steel, these barges are durable enough to get the job done and last for decades in a variety of weather conditions. These barges are typically treated with rust and corrosion protection and have roll form decks that are rated for between 5,000 lbs/sqft point load and 20,000 lbs/sqft point load. Sectional barge decks vary in size based on the weights and sizes of the loads they need to provide a base for.

Functions

Sectional barges often support cranes, both small like carry deck cranes and the largest of cranes like the Manitowoc MLC650. Various models of sectional barges can support 100 tons, 300 tons, and 500 tons or more. In both hydraulic and manual dredging operations, sectional barges offer support for both excavators and cranes. Sectionals can also attach to hoppers and dredge boxes for additional efficiency in dredging. For drilling, sectional barges can support rigs of various shapes and sizes. They can be engineered with moonpools, offering a path for workers to circumvent the drill shaft. Some sectional barges come with drill spaces that enable drilling to happen between two connected barges. Sectional barges are also useful for pile driving applications and for transporting equipment and materials across waterways or to islands.

Transport and Assembly

Usually, to offload sectional barges from a truck to water, a crane with a load capacity of at least 100 tons is required. Sectional barges typically have either a shackle or lifting clevis on top that allows for easy loading and lifting. It’s best practice to attach tag lines to the ends of sectional barges as they’re being transported in the air to control their movement.

Once sectional barges are pulled together, it’s standard procedure to have workers stand on the outer edges of the barges to ensure that they attach at the bottom. Alternately, a small choker can be threaded through barge rope thimbles to ensure conjoining barges attach at the bottom. Once the bottom is properly together, workers need to drop a pin in place to secure them.

Some sectional barges are designed to not require the use of loose parts like pins or bolts. These barges instead are constructed with locking systems that make use of “female” and “male” parts that latch into each other. Flexifloat sectional barges (and others) are designed this way. Flexifloat boasts that a platform of their sectional barges can be assembled in the matter of just a few hours.

Options and Attachments

Flexifloat and Poseidon are two of the many reputable companies that make sectional barges. When assessing different options, consider how heavy a load you need to support, the ease of assembly, the scope of the application, and the size of barge you need in order to be able to properly navigate and maneuver in your work area. Sectional barges are sold new and used and can be chartered for short-term projects.

Accessories you can add on to sectional barges to increase their versatility for certain jobs include wood crane mats, hydraulic double drum winches, hydraulic power packs for pocket mounted winches, rock/dredge boxes (as previously mentioned), sea bee pushers for easy maneuvering, and aluminum utility boats. Spud and Spudwell attachments are also useful to support and anchor floating assemblies in the face of rough currents and heavy winds. Deck cleats, bitts, and fenders are also commonly used as attachments.

Drill pipe is a hollow steel pipe that’s used to connect the surface of drilling rig equipment to the bottomhole assembly and bit. Its purpose is twofold: drill pipe both pumps drilling fluid to the bit, and it also allows the bottomhole assembly and bit to be raised, lowered and rotated. Drill pipe comes in a variety of sizes and strengths, but the pipe typically spans between 27 and 45 feet in length.

Steel Drill Pipe Manufacturing and Design

When drilling into the earth, the steel pipe must be able to transfer the drilling torque across combined lengths of pipe that often extend several miles into the earth’s crust, all while resisting the pressure and friction that comes with such deep drilling. Steel drill pipe is designed with these challenges in mind.

Drill pipe comprises of three separate elements: a box tool joint, a pin tool joint and the tube. During the manufacturing process, the ends of the tube are “upset,” which is a forging process that makes the walls at the tube’s ends thicker and increases their cross-sectional area. After the ends have been upset, the tube then goes through a heat-treating process. Drill pipe steel is commonly quenched and tempered to achieve high yield strengths, which makes it more durable and less likely to crack, dent or break.

After the steel pipe is quenched and tempered, the tool joints are cut into box (female) and pin (male) threads. All drill pipe includes these threaded ends. When the pipe is fitted to a drill, this threading creates an effective connection that allows the pipe to hold firmly to the surface of the rig equipment, even under high pressure.

Finally, the tubes and tool joints are welded together using rotary inertia. To achieve a strong weld, the tube is held stationary while the tool joint is rotated at high RPMs. The tool joint is then firmly pressed onto the upset end of the tube while the tool joint is still rotating. When they come together, the heat and force of this combination weld the two ends to each other.

The Use of Steel in Drill Pipe

Though drill pipe is sometimes made of aluminum, steel is the favored choice, mainly due to its high capacity. Steel pipe is stronger than many other types of pipe and can be made larger or thinner without compromising its durability. The strength of steel makes it a great option for drill pipe since it can withstand vibrations, shock and high pressure. Unlike other materials, steel will bend rather than break in extreme conditions, which means it’s less likely to crack or leak. It has a high torque resistance, a relatively low repair rate, better hydraulic performance, and is sustainable for use in sour environments.

Similarly, the threading of drill pipe through heat treating is a vital element of its design. The threads and joints between the tube and end pieces can be vulnerable, which is why the joints are friction welded for maximum strength and heat treated for optimum durability. Steel pipe holds up well to both friction welding and heat treatment. This ensures not only a long service life for the pipe, but also the simplification of joining and breaking, therefore cutting cycle time. In the drilling industry, this durability, reliability and simplicity is what makes steel pipe a top choice.

Because steel pipe is subject to oxidation and corrosion, the steel must be protected. One of the most popular and cost-effective ways to protect steel pipe is to coat the pipe in a protective finish. Common coating options include fusion bond epoxy, SynergyTM coating, scotch coating/fletcher coating, and galvanizing. Each of these options varies in their use and application, and different coatings will work better in different environments.

Fusion Bond Epoxy

Fusion body epoxy coating (also known as fusion bonding) is a heat applied powder coating made from epoxy-based resin and hardening agents. Due to the thermosetting properties of the resins, fusion bond epoxy can be bonded electrostatically to steel pipe through a heating process, which makes the coating more effective and longer lasting than if the pipe was simply dipped in the coating. The most efficient application method involves submerging the preheated material in a fluidized bed for a calculated period of time to achieve the desired coating thickness. Both the internal and external surfaces of steel pipe can be treated with fusion bond epoxy.

While fusion bonding is one of the most effective and durable coatings available, it can fail under certain conditions. Fusion bond epoxy coatings work best in mild environments since the coating may break down in extreme temperatures (both if the temperature is too high or too low).

Fusion bonding is commonly used in oil pipelines, sewage treatment facilities, electric power plants, food processing plants and natural gas pipelines. It has NSF-61 certification for use in potable water and FDA certification for use in food handling applications.

Synergy TM Coating

SynergyTM is a multilayer coating system consisting of a thermally activated primer, a crosslinked, thermoplastic elastomer layer, and a polyolefin top layer. These three elements are fused together with heat to create a coating that strongly adheres to steel pipe while protecting against mechanical damage. SynergyTM is impermeable to oxygen and moisture, has a high shear resistance, a low protection cost, and is touted as being durable, reliable and flexible. SynergyTM can be applied to pipes ranging in size from two inches in diameter to 36 inches in diameter.

Scotch Coating/Fletcher Coating

Scotch coating or fletcher coating (known by the brand names Scotchkote and Fletcherkote) is an epoxy powder steel pipe coating created to resist corrosion due to harsh elements, including saltwater, wastewater, petrochemicals, solvents, corrosive gases, bacteria, fungus, soil stress and backfill compaction. The coating also protects steel pipe against extreme temperatures, mechanical damage, compression, wear and abrasion.

Scotch coating is applied through a heat-cured, fusion bonding process, and its thermosetting materials allow for strong adhesion. This coating can be applied to steel pipe in a number of ways, including by a fluidized bed, flocking (air spray) or electrostatic spray.

Scotch coating is widely used in gas transmission, wastewater, potable water, non-potable water and water reclamation applications. Since the 1970s, many major energy and water transmission companies in the US have adopted scotch coatings to protect their steel pipe systems against corrosion.

Galvanizing

Galvanizing is the process of applying a protective zinc coating to steel pipe in order to prevent rusting. The most common application method is hot-dip galvanizing, which deposits a thick layer of zinc iron alloy onto the surface of the pipe. In instances where a thinner layer is needed, galvanizing can also be applied by electrogalvanizing (a process involving electroplating, where a current of electricity is run through the zinc solution with a zinc anode and steel conductor).

Galvanizing protects steel pipe by preventing corrosive substances from reaching the underlying steel. Even if the underlying metal becomes exposed, the pipe will still be protected as long as there is zinc close enough to be electrically coupled. Only after all of the zinc in the immediate area is consumed will localized corrosion of the steel pipe occur.

Galvanized steel pipe is best used where rust is an issue, particularly in pipe systems exposed to water (such as plumbing, water transport and HVAC systems).

There are many variables to consider when deciding what type of pipe to use, including things like ease of installation, versatility, resistance to corrosion, pipe strength, weight and cost. Steel pipe is a popular choice and has advantages over other types of pipe such as concrete, cast iron, copper, brass or PVC.

Versatility

Steel pipe is one of the most versatile types of pipes available, making it a top choice in a wide range of industries including construction, medical, shipbuilding, textile, agricultural, oil and gas, and more. The diameter of a steel pipe can range from a tiny tube used to make hypodermic needles to large pipes used to transport gas throughout a city. Steel pipe can be short or long, can have a thick wall or a thin one, and can be finished with varying coating materials to suit different project needs. Because of this versatility, steel pipe is often favored over other, less adaptable types of pipe, like concrete or PVC.

Installation

Unlike many other types of pipe, steel pipe is easy to install. The metal can be customized to any height, width or strength, and it can be modified on site as needed. Because of this ease of installation, steel pipe is considered one of the most convenient types of pipe to work with and is often picked over other, less versatile pipes.

Weight

While steel pipe can range widely in size and weight, it’s typically more lightweight and therefore easier to handle than other types of pipe, such as concrete. Because of its relatively lighter weight, it takes less equipment and less labor to install steel pipe, meaning the cost of installation will also be less.

Durability

Steel pipe has a high capacity. It’s stronger than many other types of pipe and can be made larger or thinner without compromising its durability. The strength of steel makes it a great option for most projects since it can withstand vibrations, shock and high pressure. Unlike other materials, steel will bend rather than break in extreme conditions, which means it’s less likely to crack or leak. In many industries, this durability is what makes steel pipe a necessary choice over other options like concrete or PVC.

Resistance to Corrosion

Steel pipe is rust resistant. Unlike other materials like cast iron, steel is long lasting and resistant to many chemical reactions that cause corrosion. While stainless steel does contain iron, which can oxidize to form rust, it also contains a high percentage of chromium, which is even more reactive than iron. The chromium in steel pipe oxidizes quickly to form a protective layer on the pipe’s surface. This layer resists corrosion and prevents oxygen from reaching the underlying steel. Additional elements in steel pipe, such as nickel and molybdenum, also add to its rust resistance. Because of this, steel pipe won’t easily corrode and will last long beyond its installation.

Longevity

Steel pipe has a low interior surface friction, remains stable at extreme temperatures, and is not affected by sunlight or ultraviolet rays, which adds to its longevity. If a steel pipe is properly treated during the manufacturing process (coated both inside and out with zinc or protective paint), the pipe can be expected to last 100 years.

The end of the fiscal year is approaching, and now might be a great time to make some last-minute investments to reduce what you owe the IRS for taxes this year. Luckily, the amount you can deduct for certain expenses has gone up in the past few years, and now you can deduct some additional purchases that you may not have been able to in the past, due in large part to Section 179 of the IRS Code.

Equipment

Investing in equipment now, before the year ends, could save you quite a bit in taxes from 2019. In most cases, you’re allowed to a federal tax deduction of up to $1.02 million on equipment and machinery you purchase before the new tax year starts in January. Both new and used equipment and machinery qualify for this deduction. This is a great option for any business owner that wants to update their fleet while simultaneously reducing taxes.

According to Section179.org, Section 179 could cover the entire cost of 2019 equipment purchases for most small businesses. Additionally, most medium-sized businesses could greatly benefit as well.

There are specific guidelines outlined by the IRS to follow when financing a piece of equipment.

Separately from Section 179, Bonus Depreciation on equipment must also be considered. As long as equipment is “new to you” (meaning new or used), bonus depreciation can apply. According to Section179.org, Bonus Depreciation is extremely useful to large businesses spending over $2.5 million on equipment.

Business vehicles

You can deduct the full cost of any vehicles you purchase that weigh over 6,000 pounds on this year’s return. This is because you can take a full depreciation deduction for them under Section 179 of the IRS Code. The vehicle section of Section 179 has been reduced in previous years, but can still save you a chunk of money in 2019.

Per Section 179, the equipment and vehicles must be used for business more than 50% of the time to qualify.

Please consult an accountant for definitive guidelines before making a purchase.

Business personal property

This is something else you can deduct under Section 179. Business personal property includes anything and everything that is not physically attached to your facilities or buildings. Common items that businesses purchase to benefit from this include computers, software, and office furniture. This year, you can deduct up to $1-million of your business personal property expenses. Now might be a great time to buy new computers for the employees in your office, especially if the computers they’re currently using are on their last legs or are negatively impacting their productivity because of their speed.

Listed property

This is property you use at least 50% of the time for business, and you can get a deduction for its cost. Listed property includes passenger vehicles that weigh under 6,000 pounds, small boats that you use both personally and for business, and digital cameras and recording equipment. Be aware that the IRS does expect you to prove that you use listed property for your business at least half of the time.

Building improvements

You can deduct any costs associated with improvements you make to your company’s buildings. Improvements can include security systems, fire safety additions, roofing, and HVAC systems. Why wait to make these improvements if you can get a cut for them from the IRS when it’s time to shell out your taxes for the year?

A good accountant

A qualified and experienced accountant can save you a big chunk of change when you pay your taxes for the year. They know the loopholes, cuts, and deductions that apply to you, and they can help you avoid paying an unnecessary amount simply because you weren’t aware of all of the tax benefits available to you. As a construction company, ensuring that your company is using the Section 179 Deduction to the company’s best benefit is very important. Investing in a good accountant now, before the year ends, could save you quite a bit when you have to pay your taxes in the spring, and it could save you quite a bit in the years to come.

Piling walls used in heavy marine construction and deep foundation applications often require high bearing capacity and stiffness. In instances where a regular sheet pile wall will not suffice, a combined sheet pile wall, also known as a “combi-wall” system, can be used.

Combi-walls are walls created using a mix of steel pipe and sheet pile. They can be temporary or permanent, and they’re a good alternative to traditional retaining wall structures such as secants or sheet pile walls.

Combi-Wall Installation

Combi-walls are built using large steel pipe and sheet piles. The steel pipe provides the bulk of the wall’s structure, while the sheet pile is used to fill in spaces between the pipes, making the wall continuous.

The steel pipe used to construct a combi-wall must be stable, heavy, rigid and straight to create a strong frame. Similarly, when installed, extreme care must be taken to ensure that the pipes are embedded straight and vertical, which will guarantee that they are parallel to each other and allow the wall to retain its integrity.

Combi-wall steel pipes are typically installed as bored pile, which is sometimes backfilled with concrete and reinforcing steel, depending on the application. A vibratory hammer is then used to install sheet pile into the spaces between the pipes. Finally, the sheet pile is aligned and welded to the pipes at interlocking points.

Combi-walls are built to be either temporary or permanent. In the case of temporary combi-walls, their elements can be deconstructed and reused later when the wall is no longer needed.

Combi-Wall Applications

Combi-walls are often used in place of secant or sheet pile walls. They’re typically seen in heavy marine construction and deep foundation projects where the piling wall must have a high bearing capacity and a regular sheet pile wall will not suffice. Some common combi-wall applications include:

• Retaining wall structures
• Building foundations
• Wharves
• Piers
• Roadway structures
• Railway structures
• Bridges
• Dams
• Lake filling
• Port expansion

Combi-Wall Advantages

Combi-walls provide a number of advantages. They have significantly more load bearing capacity than a sheet pile wall, meaning they can be used for larger projects. They’re also a cost-effective shoring alternative to the secant wall, making them a more economical option.

Combi-Walls and Steel Pipe

Combi-walls are constructed using steel pipe for a number of reasons. High-grade steel has excellent bending stiffness and resistance, creating a more reliable wall. Unlike other metals, steel will bend rather than break in extreme conditions, which means it’s less likely to crack or leak. Similarly, the strength of steel makes it a great option for combi-walls since it can withstand vibrations, shock and high pressure.

Steel pipe is rust-resistant. Unlike other metals, steel pipe is long lasting and resistant to many chemical reactions that cause corrosion. For permanent combi-walls, steel pipe is low maintenance and will last long beyond its installation.

Steel pipe is easy to install. The metal can be customized to any height, width or strength, and it can be modified on site as needed. Because of this, steel pipe is considered one of the most versatile and convenient types of pipe to use.

Finally, steel pipe has a high capacity. It’s stronger than most other types of metal and can be made larger or thinner without compromising its durability. In combi-wall construction, this durability is what makes steel pipe a necessary choice. To learn more about steel pipe, check out our blog titled "All About Steel Pipe".

A steel pipe fitting is a piece of steel used to connect separate sections of pipe together. Fittings can be used to extend lengths of pipe or to create angles in a piping system, and they’re necessary to regulate and manipulate the flow of air or fluid. Steel pipe fittings come in a variety of shapes and styles including tees, adapters, elbows, couplings, unions, reducers, and more.

Tee

A tee is one of the most common types of pipe fittings and is used to combine or divide the flow of fluids. Tees have three openings to create a “T shape” and most often connect pipes of identical sizes, though they can be used to connect pipes with varying diameters as well.

Adapter

A steel pipe adapter is a fitting that connects together pipes of different materials or sizes. There are several varieties of adapters, including expansion adapters, bell adapters and adapter spools. Expansion adapters are designed with a flexible section that can absorb the expansion or contraction from two dissimilar pipe materials. Bell adapters have a stainless-steel backup ring to keep the seal between their adjoining pipes tight. Finally, adapter spools have openings on each end with different diameters, allowing pipes of different sizes to be connected.

Elbow

An elbow is an adapter that’s installed between two lengths of pipe to create a change of direction. Elbows are typically designed at 45-degree angles (called a “45 bend”) or 90-degree angles (called a “quarter bend”), though 22.5-degree elbow fittings are sometimes also used. Elbows are commonly applied in water-supply facilities, food, chemical and electronic industrial pipeline networks, agriculture and garden production, air conditioning pipelines, and solar energy facility piping. Similarly, longer pipe elbows can be used in low pressure, gravity fed systems.

Cross

A cross, also known as a four-way fitting, is the center point of a four-way connection, with one inlet and three outlets. Because they are at the center of four connection points, cross fittings may cause stress to pipes, especially as temperatures change. Crosses are commonly used in fire sprinklers and other systems where temperature change is not an issue.

Coupling

Like an adapter, a coupling connects two pipes together. However, where an adapter is meant to connect two pipes of different materials or sizes, a coupling connects like pipes. There are two types of steel pipe couplings: regular and slip. A regular coupling has a small ridge in its center that prevents a pipe from being over-inserted (which would result in the under-insertion of the second pipe and therefore a compromised connection). A slip coupling, on the other hand, is made without this ridge, allowing it to be slipped into place at any level. Slip coupling is often used in pipe repair, such as in instances where a pipe has a leak or had to be cut temporarily during a project.

Union

Like a coupling, a union connects two identical pipes, but it’s different in that it allows for easy disconnection of the pipes. Unions are most often used in systems where disassembly is necessary, such as those that require maintenance. A union consists of three parts: a nut, a female end and a male end. When the female and male ends are connected, the nut is used to seal the joint.

Nipple

A nipple is a short steel stub of pipe that connects two other fittings of equal diameter. Nipples are commonly used in plumbing systems and with hoses.

Cap

A cap is an airtight cover that is used to close the open end of a pipe. Caps attach to the outside of pipes and may be round, square, rectangular, U-shaped or I-shaped.

Reducer

A steel pipe reducer connects a pipe with a larger diameter to a pipe with a smaller one. Reducers are often necessary to meet a system’s hydraulic flow requirements, or to adapt an existing pipe to one of a different diameter. Reducers come in many sizes and can be made to match pipes with a range of diameters.

The Traffic Engineering Branch in Manitoba has established fairly specific requirements for use of road barrier systems. Whether you’re looking to install W-beam barriers, thrie beam barriers, pre-cast concrete barrier walls, cable systems, or sand-filled crash prevention barriers, Manitoba has outlined which kinds are permissible to use on roads to help keep drivers and road projects unharmed. Below are the approved types of barrier systems and their corresponding classifications:

• W-Beam: This type of barrier is composed of plastic, wood, or steel. In semi-rigid forms, the W-Beam Trailing End Terminal/Foundation Tube Option (TSEW02a)*, Strong Post W-Beam Median Barrier (TSGM04b), and Strong Post W-Beam Guardrail (TSGR04b) are permissible. W-Beam also can serve as a transition structure if nested and connected to a 2 Rail PL-2 Bridge, timber bridge, thrie beam, or guardrail.

• Thrie Beam: This type of barrier is a semi-rigid, steel post structure. Approved thrie beam types are: Thrie Beam Trailing End Terminal – Foundation Tube Option (TSET02a), Strong Post Thrie Beam Median Barrier (TSGM09c), Strong Post Thrie Beam Guardrail (TSGR09c), Nested Thrie Beam to Vertical Wall Transition (TSTB05), Nested Thrie Beam Approach Guardrail to Newel Post Transition (TSTB07), Nested Thrie Beam to 3 Rail Newel Post Transition (TSTB08), Nested Thrie Beam to 5 Rail Newel Post Transition (TSTB09), Nested W Beam to 2 Rail PL-2 Bridge (TSTB10), Nested Thrie Beam to 2 Rail PL-2 Bridge (TSTB11), and Nested Thrie Beam Approach Guardrail to 2 Rail Newel Post Transition (TSTB12).

• F-Shape Precast Concrete Barrier: F-shape is the only allowed shape for new projects. Jersey-shape barrier is not allowed on new projects. F-shape barrier wall should be rigid and move minimally upon impact. The concrete of F-shape barrier walls should have a minimum of 28 MPa compressive strength. All barrier wall top edges should be rounded with a 25 mm radius. Maximum spacing should be 1350 mm. Allowed types of F-shape barrier wall include: median barrier wall (TSGM10a), roadside barrier wall (TSGR10a), roadside barrier tall wall (TSGR10b), and transition barrier wall (TSTG10). Note: F-shape transition barrier wall must be connected to other F-shape barrier wall systems. It is not compatible with other types of precast concrete barrier wall.

• Cable Guardrail: Cable Guardrail Anchor (TSEC01), Cable Guardrail Intermediate Anchor (TSEC02), Cable Guardrail Intermediate Anchor (TSEC03) types are allowed. All cable guardrail types are classified as flexible.

• Crash Attenuators: The following crash attenuators are approved: Sand Filled Barrels – 50 km/h (TSFB50), Sand Filled Barrels – 60 km/h (TSFB60), Sand Filled Barrels – 70 km/h (TSFB70), Sand Filled Barrels – 80 km/h (TSFB80), Sand Filled Barrels – 90 km/h (TSFB90), Sand Filled Barrels – 100 km/h (TSFB100), and Sand Filled Barrels – 110 km/h (TSFB110). Sand should contain, at a minimum, 5% of rock salt by weight.

*Numbers following approved barrier system types correspond with official Manitoba numbers for drawings of systems.

Flexible, rigid, and semi-rigid classifications depend on design deflection, or how much a particular system moves once impacted by a vehicle or other object. Flexible systems move around 3.5m. Rigid systems move around 0m (basically not at all). And semi-rigid systems move 1.5m or less than 1.5m.

Manitoba uses NCHRP 350 guidelines to establish specs for its approved barrier wall systems. NCHRP 350 guidelines are based on rigid testing of strength, materials, and design deflection of the barrier wall systems. Before investing in any particular kind of barrier wall, you should refer to drawings to ensure the specifications are aligned with the province’s current standards and to ensure that the barrier wall system meets NCHRP 350 or other Manitoba-approved standards. A number of manufacturers in Manitoba make approved barrier wall systems. If in doubt, it may be a good idea to contact the manufacturer of a particular barrier to double-check that it meets the Traffic Engineering Branch’s requirements. Requirements are subject to change, and it’s always a good idea to stay in-the-know!

Steel pipe comes in a wide range of sizes, from large pipes used to transport gas throughout a city to the small diameter pipe used as micro piles. Steel pipe can be short or long, can have a thick wall or a thin one, and can be finished with varying coating materials. Because steel is malleable and versatile, it’s often used to create small diameter pipes.

Small Diameter Steel Pipe Dimensions

The size of small diameter steel pipe varies depending on the application, but diameters in the heavy civil and oil and gas sectors are typically under 10” outside diameter.

Small Diameter Steel Pipe Styles

Just as with large steel pipe, small diameter steel pipe can be seamless or welded. Seamless steel pipe is manufactured in such a way as to be smooth all the way around (without a weld), while welded steel pipe will have a straight or spiral seam running along its side.

Small Diameter Steel Pipe Applications

Small steel pipe has a wide range of applications and is used for heat exchanger tubes, control lines for oil and gas, micro piling, excavating, and more. In addition, small diameter pipes have applications in different industries, specifically in the aerospace and nuclear sectors.

Micro Piling

Micro piles, also known as “minipiles”, “pin piles”, and “needle piles”, are small diameter steel pipe piles used for deep foundation projects. Typically, the steel pipe piles are bonded into the soil with cement grout. This technique is used for structural support in weak soils, and work to essentially “stitch” the soil together to create more stability and a stronger base. In addition, the micro pile technique can be utilized to transfer loads. The micro piling technique is a very cost-effective method for foundation stabilization.

Excavating

Hollow steel pipe is often called casing. Casing is utilized in a variety of ways, including pile driving, groundwater protection, drilling, oil and gas, excavating, and much more. One way that temporary casing is used is for stabilization during the excavating process to stabilize the drilled shaft. Sometimes, multiple smaller diameter casings are used progressively, called a telescope casing process.

Hydraulic Lines

The aerospace industry uses small hydraulic tubes in the engines and airframes of both commercial and military aircraft. Small steel pipe works well in this setting because of its high strength to weight ratio. The diameter of hydraulic lines ranges from 0.125 inches to 1.5 inches and is used to trigger flight control surfaces such as flaps and slats. The pipe is also necessary for things like landing gear and brakes.

Instrumentation Tubes

Both the aerospace industry and the nuclear power industry rely on precision tubing to protect their control systems and instruments. For example, pilots rely on pitot tubes to measure flow speed while in the air. Similarly, control and measuring devices are critical to the safe functioning of nuclear reactors. Each of these industries utilize steel instrumentation tubes to monitor factors such as pressure, temperature, density differences and fuel burn up rates. Instrumentation tubing is most commonly made of special grade stainless steel and can range in diameter from 0.020 inches to 1.5 inches.

Heat Exchanger Tubes

Heat exchanger tubes heat or cool gases and air. They’re used by a wide range of industries, including the chemical processing, oil and gas, alternative energy, nuclear and aerospace industries. Small diameter steel pipe is required to manufacture heat exchanger tubes due to its high strength and resistance to corrosion.

Control Lines

The oil and gas industry requires continuous lengths of steel control lines, which are used for a variety of applications including hydraulic controls, chemical injections and flowline controls.

Nuclear Control Rod Tubes

Small diameter steel pipe is used in the nuclear power industry inside the cores of nuclear reactors. For example, pipe is used in control rod and cladding tubing, which ranges in diameter from a 0.25 inches to 1.0 inch.

High Pressure Tubes

High pressure tubes have many applications, including oil and gas extraction, high pressure liquid chromatography, military uses, water jet cutting and more. Small diameter steel pipe is used to create the high-pressure tubes needed for these systems.
