Tips & Advice Posts

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.To learn more about steel pipe, check out our blog "All About Steel Pipe".

In British Columbia, F-shape barriers, constant slope barriers, and vertical face barriers are all allowed types of pre-cast concrete barrier systems. Currently, Jersey shape barrier is not permitted unless previously installed as a part of an older road project and properly maintained. Each of the permitted types of pre-cast concrete barrier walls must meet stringent requirements and must be originally manufactured by an approved distributer.Below are the distributors who make pre-cast concrete barrier walls that meet British Columbia’s requirements:

• Coast Range Concrete Ltd.
• Grosso Precast DBA Northern Vac Services
• Kemp Concrete Products
• Kon Kast Products (2005) Ltd.
• Skeena Concrete Products Ltd.
• Tri-Kon Precast Concrete Products Ltd.
• Eagle West Truck & Crane Inc.
• Surespan Structures

These manufacturers must clearly mark approved barrier walls with their name or trade mark, the year of manufacture, and the form number.The British Columbia Ministry of Transportation stipulates that the concrete used to make any barrier walls must meet certain requirements. Here’s what you should know about concrete standards:

• The quality of concrete needs to conform to CSA Standard CAN3-A23.1-M.
• Concrete strength must be 30 MPa, with no individual cylinder less than 27 MPa.
• Concrete testing cylinders need to be cast by precast suppliers or by an authorized supplier representative at the time the concrete is placed.
• Calcium chloride or any mixtures that contain calcium chloride must not be used, as they may compromise the quality of the concrete.
• The minimum cement content of concrete should be 320 kg per cubic meter.
• The maximum water/cement ratio should be: 0.45.
• The course aggregate of a nominal maximum size should not exceed 28 mm.
• There should be a slump of 50 mm ± 20 mm.

In addition to these concrete specifics, the province also requires the following for reinforcing steel, attachment hardware, and fibrillated fibers:

• Welded steel and mesh reinforcements should be installed according to details in BC Ministry of Transportation’s SS 412.
• Fibrillated fibers may be used as a substitute for welded wire mesh. However, they need to meet ASTM C 1116 Type 3 requirements.
• Fibers should be a minimum of 50 mm in length, added at a dosage rate of 1kg/m3.
• Fibers should be mixed with concrete before it is placed into forms.
• Fibers should have a minimum tensile strength of 350 MPa in addition to a minimum modulus elasticity of 4.2 GPa.
• All suppliers of fibers should furnish proof that they meet ASTM C 1018 or ASTM C 1399 requirements.
• Reinforcing steel used in bent or hooked connections should be CSA CAN3-G40.21-M Grade 260W.
• Pick-up points for handling units should be made with rigid PVC pipe, recessed 15mm.

And here are some general notes about the proper placing of pre-cast concrete barrier systems, according to BC regulations:

• Concrete should be placed in forms according to CSA CAN3-A23.4-M, Clause 19 standards.
• Curing and protection should be done according to CSA CAN3-A23.4-M, Clause 21 standards.
• Exposed surfaces should be uniform in color/texture. Formwork should possess well-maintained steel.
• Patching must be authorized. The area in need of repair needs to be saturated with water and patched up with cement paste filled with mortar.
• All end connection surfaces should be cleared out.
• End connections must be compatible with the particular type of barrier wall being used.

For more details about the proper use of pre-cast concrete barrier walls in British Columbia, see the BC Ministry of Transportation’s official Standard Specifications for Highway Construction. And please note that it is always better to check in with an expert from the Ministry of Transportation before you begin using any kind of pre-cast barrier wall you believe may not meet the agency’s requirements.To learn more about barrier wall, check out our blog titled "Barrier Wall Styles and Uses"

Surplus steel pipe is pipe that has been previously purchased but unused. Many times, if a contractor has already purchased steel pipe for a project that gets canceled, the pipe will be stored in a yard for a period of time. There are many benefits to surplus steel pipe, mostly involving the cost savings.

Where Does New and Surplus Steel Pipe Come From?

New or “prime” steel pipe is one of the most commonly used products in the steel industry, and each year millions of tons of steel pipe are manufactured and sold around the world. Surplus steel pipe, on the other hand, does not come directly from the manufacturer but rather from a job site or other location where it’s been previously stored.It’s a common misconception that surplus steel pipe must be old, dirty or corroded, but this isn’t always the case. Sometimes surplus steel pipe looks and functions as brand new. Surplus steel pipe might be sold as “used” or “surplus” if the pipe was left over from another project, such as in instances where more pipe was ordered than needed, or where scraps of pipe were left over from being cut. In these cases, the pipe cannot be resold as new, but buyers can purchase the top quality material at a lower rate. Similarly, new steel pipe might be resold as surplus in instances where the pipe was ordered but rejected on site. This might happen if the material was improperly cut, the wrong size was ordered, or the project was cancelled.Additionally, used steel pipe is very common on the market. Excess steel pipe is commonly created when companies upgrade their systems, and the old pipe can be resold. Similarly, if a company upgrades to a different type of pipe or to a system with a different pipe diameter, lightly used pipe will be available.

When to Choose Surplus Over New Steel Pipe

In many cases, surplus steel pipe is just as effective as new steel pipe and can be used successfully in its place. Surplus steel should always be tested for pressure resistance and durability before use, and pipe that doesn’t pass the test should only be used in light-duty situations. Surplus steel pipe can be utilized for structural work, reinforcement projects (such as bulkheads), deep foundations, drainage, and, more. Surplus steel pipe can be used as a surface casing or road bore casing, which is pipe that’s used beneath roads to hold together smaller pieces of pipe.

When Should Surplus Steel Not Be Used?

When purchasing surplus or used steel pipe, it is always important to perform an inspection on the pipe. Eiffel Trading’s expert account managers are always available to set up inspections and to assist you in the purchasing process!To learn more about steel pipe, check out our blog titled "All About Steel Pipe".

The province of Alberta has well-defined requirements for barrier systems for both roadside barriers and median barriers. Alberta uses the recommendations of the National Cooperative Highway Research Program (NCHRP) to establish these requirements, and all barrier systems used in the province must meet specific ratings established by NCHRP in their Report 350. Below are the system types approved for roadside use in Alberta with some information about their specs:

Roadside Barriers:

• Alberta Weak Post W-Beam: This beam is made of plastic or wood. It’s defined as “flexible” in terms of resistance to force. Its minimum system length is 22.86m for areas with speed limits under 70 km/hr and 45.72m for areas with speed limits over 80 km/hr.• High Tension Cable: This type of roadside barrier is made of steel. Its resistance to force is rated as “flexible.” And it meets TL-3 or TL-4 NCHRP guidelines.• Cast-in-Place Barrier: Made of durable concrete, Alberta authorities classify this barrier as “rigid.” The cast-in-place barrier must meet either TL-4 or TL-5 standards established by the NCHRP. Cast-in-place barrier should have a minimum system length of 30m.• Modified Thrie Beam: This is a semi-rigid steel post with a minimum system length of 50m. It meets TL-4 requirements.• F-Shape Precast Concrete Barrier: According to crash tests, this concrete barrier wall should offer semi-rigid strength. It should also meet TL-3 requirements and have a minimum system length of 45m. Note: New Jersey style precast concrete barrier may be used if replacing or repairing a section of existing barrier that is in the New Jersey style barrier. This would be the case if New Jersey style barrier was installed for a road project before Alberta updated their standards to require use of F-shape barrier. New Jersey barrier wall and F-shape barrier wall must never be combined.• Standard Thrie Beam: A semi-rigid, steel post type barrier, this differs from the modified thrie beam in that it must meet TL-3, rather than TL-4 requirements. Its minimum system length is 50m.• Strong Post W‐Beam: Made of either plastic, wood, or steel, it must be semi-rigid in strength and have a minimum system length of 50m.• Weak Post Box Beam: This is a steel post system with semi-rigid strength. It must be TL-3 approved, and its minimum system length is 100m.Note: Whether a barrier system is considered, flexible, rigid, or semi-rigid is based on design deflection, or the distance the system moves upon impact, measured at the face. In general, flexible systems move 3.5m upon impact. Rigid systems move 0m (or minimally if at all). And semi-rigid systems move 1.5m or less.The requirements for median barriers in Alberta differ slightly from the requirements for roadside barriers, particularly in terms of required NCHRP ratings. This is because roadside barriers are engineered to be impacted on one side only, while median barriers must be able to withstand force from both sides. Here are the approved types of median barriers in the province with their necessary NCHRP ratings:• Cast‐In‐Place F‐Shape Concrete Barrier: TL-4 or TL-5• Cast‐In‐Place Single Slope Concrete Barrier: TL-4 or TL-5• High Tension Cable Barrier Systems: TL‐3 or TL‐4• Modified Thrie Beam: TL-4• Precast F‐Shape or Single Slope Concrete Barrier: TL-3• Strong Post W-Beam (wood, steel, or plastic posts): TL-3• Weak Post Box Beam: TL-3It’s important to be aware that all F-shape, pre-cast concrete barrier used in median areas must be rigid and have minimal design deflection. This notably differs from the semi-rigid requirement for F-shape barrier if used roadside. Additionally, both roadside and median pre-cast concrete barrier in Alberta needs to use crash tested joints between units. In either instance, use of joints between units allows for greater strength and less movement upon impact.To learn more about barrier wall, visit our blog titled "Barrier Wall Styles and Uses".

The three main styles of steel pipe are seamless, straight weld or spiral weld, named for the way in which they are manufactured. Though these three types of pipe can often be used interchangeably, some styles of pipe are better suited for certain projects.

What All Steel Pipe Has in Common

The main raw material used in all steel pipe production is steel, which is made up primarily of iron. However, steel pipe commonly includes other elements such as aluminum, manganese, titanium, tungsten, vanadium and zirconium. No matter whether the pipe is seamless or welded, steel pipe is durable, rust proof, easy to install and highly customizable, making it a top choice in a wide range of industries.

How Straight Weld Steel Pipe Is Made

Straight weld steel pipe is made by taking a long, coiled ribbon of steel called a skelp and cutting it into a flat rectangular sheet. From there, the steel is fed through a rolling machine that forces the edges of the rectangle together to create a cylinder. Finally, the cylinder is sealed with a weld. Once completed, straight weld steel pipe will have a single, straight seam down its length.

How Spiral Weld Pipe Is Made

Just as with straight weld pipe, spiral weld pipe is created by casting raw steel and then forcing the edges together, finishing the pipe by sealing it with a weld. The difference is that the coil is wound at an angle, so the weld runs around the outside of the pipe in the shape of a helix, rather than in a straight line. This allows for more variation in the pipe’s diameter and thickness.

How Seamless Steel Pipe Is Made

Seamless steel pipe is made by stretching steel out into a seamless tube. The pipe begins as a solid cylindrical block of steel called a billet. The billet is heated and pierced through the center with a mandrel, after which the steel is rolled and stretched until it meets the required length, diameter and wall thickness. Unlike straight and spiral weld steel pipe, seamless steel pipe has no seam.

Best Applications for Straight and Spiral Weld Steel Pipe

Generally, welded pipe is considered weaker because of its seam. Though improvements have been made in the manufacturing process and quality assurance regimens have enhanced the performance of welded steel pipe, it is typically used for lighter weight applications such as transporting gas, electrical conduit and plumbing. Welded steel pipe is cheaper than seamless steel pipe.As mentioned above, the spiral weld on spiral weld steel pipe allows for more variation in the pipe’s diameter and thickness, and it is commonly favored when making custom pipes. Spiral weld is most often used for pipe diameters between 24 inches and 120 inches, and for thicknesses of 1 inch or less.

Best Applications for Seamless Steel Pipe

Seamless pipes lack a weld and are generally considered safer, making it a top choice high-pressure, high-temperature applications, such as those in oil and gas, power generation and the pharmaceutical industry. Seamless steel pipe is also more lightweight and has thinner walls, which makes it excellent for things like bicycles and to transport liquids. The downside of seamless steel pipe is that the rolling and stretching manufacturing process produces an inconsistent wall thickness compared to welded pipe, and it’s also more expensive to purchase.If you would like to learn more about steel pipe, more information can be found in our blog post, "All About Steel Pipe."

There are many variables to consider when deciding whether to use steel pipe or concrete, including things like ease of installation, longevity, resistance to corrosion, pipe strength, weight and cost. Though some jobs might allow these pipes to be used interchangeably, most are better suited for one or the other.

Installation

Concrete Pipe

One of the biggest challenges in working with concrete pipe is its installation. Properly installed, concrete pipe can last for decades. Improperly installed, however, the pipe can quickly fail. Concrete pipe requires expert and careful installation, and small errors can dramatically shorten the life of the pipe.

Steel Pipe

Steel pipe is easy to install. The steel 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. On the downside, steel pipe is relatively expensive to install compared to concrete.

Longevity

Concrete Pipe

Much of the life expectancy of a pipe has to do with its resistance to corrosion. Concrete is resistant to corrosion, except in situations where there are highly acidic compounds in the soil or wastewater, in which case the concrete might need a separate coating of plastic material to prevent corrosion. If installed correctly, concrete pipe can last between 75 and 100 years. Similarly, concrete has a high breaking point, which allows for higher operating pressures and less risk of root intrusion.

Steel Pipe

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.

Strength

Concrete Pipe

Concrete pipe has long been considered one of the strongest and most durable building materials available, and it is often used in the construction of storm water drains, sewers, culverts, and other projects requiring heavy loads and a high amount of water flow.

Steel Pipe

Steel pipe boasts more mechanical strength and durability than other metals like iron. Steel is resistant to bursting from mechanical force, since the metal tends to bend rather than break under high pressure.

Weight

Concrete Pipe

Concrete pipe is heavy, which creates difficulties during installation. Often, more equipment and labor is required to install concrete pipe as opposed to steel.

Steel Pipe

Steel pipe ranges in size and weight, but often it’s more lightweight and therefore easier to handle and install than concrete pipe.

Cost

Concrete Pipe

Concrete pipe is typically cheaper to purchase and install than steel pipe. When considering cost, it’s important to look at the costs of the initial design, construction, materials, inspection and maintenance for the pipe. Concrete is typically considered a “low cost” pipe because it does not require additional investments for repair or maintenance over its lifetime.

Steel Pipe

The price of steel pipe purchase and installation can vary greatly depending on its application. However, when using steel pipe in comparable situations to concrete pipe, steel pipe is typically more expensive to purchase and install. The design, installation and inspection costs of steel pipe are on average larger than comparable concrete pipe costs.

Versatility

Concrete Pipe

Concrete pipe has a relatively low versatility when compared to steel pipe. It’s mainly used in the construction industry and is prevalent in water and sewage transportation.

Steel Pipe

Steel pipe is one of the most versatile pipes available, making it a top choice in a wide range of industries including construction, medical, shipbuilding, textile, agricultural and oil and gas, and more. Since steel pipe is both durable and lightweight, it’s commonly used in city water, gas, heating and plumbing systems, as well as in everyday items such as fridges, bicycles, flagpoles and cars.To learn more about steel pipe, check out our blog post titled "All About Steel Pipe".

Steel pipe is durable, rust resistant, easy to install and highly customizable, making it a top choice in a wide range of industries including construction, shipbuilding, textile, agricultural, oil and gas, and more.

1) THE CONSTRUCTION INDUSTRY

Since steel pipe is both durable and lightweight, it’s commonly utilized by the construction industry in commercial and residential buildings, as well as in industry sectors including power, water, sewer, manufacturing and more. Steel pipe is also a top choice in the construction industry because it’s resistant to rust and corrosion, meaning that it won’t require frequent repairs or replacement. This is especially important in water, plumbing and electrical systems, since leaks or breaks in the steel pipe can be both dangerous and costly.

2) THE OIL AND GAS INDUSTRY

Steel pipe is ideal for use in extreme conditions such as corrosive environments, low and high temperatures and high pressure. For this reason, steel pipe is prevalent in the oil and gas industry, especially in pipes like gathering lines (the tubes that transport oil or gas from the producing area to a storage facility or larger main pipeline), and pipe trunk lines (the welded, large-diameter steel pipes that are used to transport natural gas over long distances). Because of steel pipe’s durability and versatility, it can stand up to the unique needs of the oil and gas industry.

3) THE SHIPBUILDING INDUSTRY

The strength of steel makes it a great option for ship building since it withstands vibrations, shock and high pressure. Unlike other metals, steel with bend rather than break in extreme conditions, which means it’s less likely to crack or leak. In the shipbuilding industry, steel pipe is designed and manufactured for the boilers, super heaters and pressure systems of a ship.

4) THE TEXTILE INDUSTRY

The versatility of steel pipe makes it a popular choice in the textile industry for the production of bale openers, mixers, carding machines, spinning machines, winding machines and texturing machines.

5) THE AGRICULTURAL INDUSTRY

Steel pipe is frequently used in agricultural fittings due to its durability and ability to withstand pressure. Steel is also sometimes mixed with carbon to create a more lightweight yet sturdy agricultural fitting. Farmers and other agricultural organizations use steel pipe in dozens of applications, including tractor engines, grain elevators, field drainage systems, fertilizer applications, vent pipe systems and more.

6) INDUSTRIAL APPLICATIONS

Steel pipe is a common choice in manufacturing facilities, warehouses and other industrial locations because it’s rust-proof and doesn’t corrode, affording facilities a lifetime of dependable use. Round steel tubing is often used to transport liquids or gas from one area of an industrial facility to another, as well as in the construction of industry structures itself.

7) ADDITIONAL APPLICATIONS

In addition to the above listed, steel pipe is commonly found in:• Power Plants• Diary and Food Processing Facilities• Modern Architecture• Chemical Facilities• Water Treatment Facilities• Synthetic Fiber Production• Desalination• Energy IndustriesThere are many benefits to using steel pipe, including its easy installation, long service life, and durability.

Steel pipes are long, hollow tubes that serve a wide range of functions. Their versatility makes them one of the most commonly used products in the steel industry, and each year millions of tons of steel pipe are manufactured and sold around the world. Since steel pipe is both durable and lightweight, it’s commonly used in city water, gas, heating and plumbing systems, as well as in everyday items such as cars, flagpoles, street lamps and fridges. Similarly, steel pipe is often utilized by the construction industry in shipbuilding, architecture, oil refineries and more.

Steel Pipe History

Though the invention of the pipe can be traced back to ancient China (where people used hollow reeds to transport water), the modern day welded steel pipe has its origins in 19th century London. In the early 1800s, William Murdock invented the coal burning lamp system, but he had no way to easily outfit the city of London with these lights. As a solution, he joined together the barrels of discarded muskets, creating a continuous pipeline that could transport the gas. His lighting system was a success, and it created demand for long metal tubes in other industries—hence, the beginning of the steel pipe.

How Steel Pipes Are Made

Since its introduction in the early 1800s, steel pipe production has slowly evolved into the process used today. Steel pipes are made by casting raw steel into a more workable starting form. From there, the pipes are molded in one of two ways: by stretching the steel out into a seamless tube, or by forcing the edges of the steel together and sealing it with a weld. In the first method, the final steel pipe will have no seam. If the second method is used, the pipe will have a seam.

Welded vs. Seamless Steel Pipe

Welded steel pipes—the ones with a seam—are used differently than seamless steel pipes. Seamless pipes are typically more lightweight and have thinner walls, and they’re used to make things like bicycles and liquid transportation pipes. Welded or seamed pipes, on the other hand, are heavier and better for transporting gas, electrical conduit and plumbing.

Steel Pipe Materials and Characteristics

The main raw material used in steel pipe production is steel, which is made up primarily of iron. However, steel pipe commonly includes other elements such as aluminum, manganese, titanium, tungsten, vanadium and zirconium. Similarly, finishing materials are sometimes applied to help protect the pipe.Steel pipes come in a wide range of shapes and styles. 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. They can be short or long, have a thick wall or a thin one, and can be finished with varying coating materials. Often, steel pipes are manufactured for an intended purpose, and their characteristics are modified during production to better fit their task.

The Popularity of Steel Pipe

Steel pipe is popular for many reasons. First, it’s durable. The strength of steel makes it a great option for most projects since it can withstand vibrations, shock and high pressure. Unlike other metals, steel with bend rather than break in extreme conditions, which means it’s less likely to crack or leak.Unlike other metals, steel pipe is long lasting and resistant to many chemical reactions that cause corrosion. For this reason, 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 kinds of pipe.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 many industries, this durability is what makes steel pipe a necessary choice.

K-rail barriers are concrete, steel-enforced barriers used to divide lanes of highway traffic. Though these barriers were originally designed to prevent head-on collisions, they’ve since been adapted to protect perimeters, define walkways, and block access to construction zones, sports arenas, concerts, and more.

1) They’re Mostly Called K-Rails In California

Though the K-rail barrier has its origins in California, the original design was adapted and improved by the state of New Jersey to separately be called jersey barriers. Today, k-rail barrier wall is most commonly employed in the pacific region, including California.

2) They Have a Unique Backstory

Before the concrete highway barrier, wooden guardrails were used to separate lanes of traffic. Unfortunately, these guardrails were flimsy and did little to stop out of control vehicles from veering into oncoming lanes. This problem was particularly prevalent along a stretch of California highway nicknamed “Dead Man’s Curve,” which is known for its steep, sloped incline. As a solution, the original wooden guardrails were replaced by concrete barriers. These new barriers successfully reduced the number of deadly head-on collisions along Dead Man’s Curve, and their design was quickly adopted across the U.S.

3) They are Designed to Minimize Damage

When the state of New Jersey took over the K-rail design, its engineers crafted the barriers not only to stop head-on collisions, but also to prevent damage to incoming cars (and injury to vehicle passengers). In shallow-angle hits, a car’s tires will ride up the sloped face of the barrier, which forces the car to pivot away from oncoming traffic and back into its original direction. Furthermore, this “slide” prevents vehicles from rolling over, further protecting passengers from injury.

4) They’re Made with Precast Concrete

Usually, a K-rail barrier is made of poured concrete that is reinforced with embedded steel. The steel reinforcements protrude from each end of the barrier, allowing separate segments to be linked together. There are various types of barrier wall connections including JJ-hook connections, loop and pin connections, and more.

5) Their Design Has Improved, But It’s Not Perfect

While today's K-rail barriers are better at preventing rollover accidents, they’re not perfect. If a car is too small, the K-rail design is less effective, and the car might roll over anyway. To address this problem, an alternate barrier was created, which is known as the F-Shape barrier. F-Shape barriers have the same 3-inch-high base as a K-rail barrier, but they feature a side that slopes 10 inches above the pavement rather than the 13-inch side slope of the K-rail, which allows them to better absorb impacts from smaller vehicles.
