How is Steel Pipe used in Marine Construction?

Tips & Advice

Steel pipe is indispensable to many marine construction projects. It can be used to help build trestle, combiwalls, and bridges. Steel pipe piling is commonly used to create deep foundations for bridges and other marine structures. Since the elements in marine areas can be pretty harsh on construction materials, the use of durable steel pipe is beneficial because it tends to stay protected from corrosion. In addition to stainless steel pipes, carbon steel pipes, carbon steel pipes with eproxy coating, hot-dip galvanized carbon steel pipes, and duplex stainless steel pipes are all used in marine construction. Below are some details regarding specific applications of steel pipes in marine construction:

Trestle Construction

Trestle serves as a framework to support structures like bridges, often temporarily while they are under construction. Steel pipe piles are often used to create trestle. To construct a trestle, steel pipe piles are driven deep beneath soil into rock surfaces near river, lakes, and oceans. Once driven into the ground, they are customarily strengthened by reinforced concrete to stay in place.

Combiwall Construction

Combiwalls are piling walls constructed using a mixture of steel pipe and sheet pile. They are frequently used to create deep foundations for a variety of marine construction projects. They provide more strength and durability in comparison to traditional sheet pile walls. In combiwalls, steel pipe makes up most of the wall’s structure. Sheet pile is employed to connect pipes and make the walls continuous. Combiwalls are useful in construction projects involving lake filling, port expansion, dams, bridge construction, pier construction, wharf construction, and retaining wall structure construction.

Bridge Construction

Steel pipe piling is often used to build the foundation for bridges. The use of steel pipe creates a strong foundation and ultimately enhances the structural support of a bridge. This is because steel pipe can be driven deep below layers of weaker soil into rock formations.

Dock Construction

As is the case for other applications, steel pipes can be driven deep into the ground and secured to provide adequate support for docks. Steel pipe piling for a dock provides a considerable load capacity in addition to offering corrosion resistance. It is most common for steel pipe piling that has been treated with anti-corrosive coating to be used for the building of docks.

The list above of how steel pipe is used in marine construction is not exhaustive. Anytime any sort of platform, pier, or marina is built, steel pipe piling can be used to help build strong foundations. The specific type of steel pipe used depends on the needs of the project. Below is some information about different steel pipe options:

  • Carbon Steel Pipe is the most affordable option but the most likely to suffer from corrosion due to saltwater. Carbon steel pipe can be treated with internal galvanizing, epoxy coating, or inner plastic coating to prevent damage from corrosion.

  • Stainless Steel Pipe is the standard choice for marine construction. It’s impressively anti-corrosive and is designed to be strong, durable, and long-lasting.

  • Hot-Dip Galvanized Carbon Steel Pipe is carbon steel pipe that has been coated with zinc to help prevent corrosion.

  • Duplex Stainless Steel Pipe has the added advantage over traditional stainless steel pipe of preventing pitting corrosion from sulfur in sea water.

Steel pipe comes in various sizes and can be cut to size to suit the needs of particular projects. You can buy steel pipe both new and used. Buying new may be the best option if you need the pipe customized. Buying used may be a solid choice if you know a particular size of steel pipe will work for you. Overall, steel pipe is a very versatile option for marine construction projects, particularly those that require a strong foundation.
