What is welded steel pipe?

The production of welded steel pipe involves the use of a flat steel plate or strip, which is bent and welded into a cylindrical or square shape, resulting in a seam on the body of the pipe.

What is the difference between ERW and DSAW?

One benefit of ERW pipe is that it doesn't require the use of fusion metals, resulting in a seamless finish that is both visually and tactilely undetectable. This sets it apart from double submerged arc welding (DSAW), which produces a conspicuous weld bead that may need to be removed depending on the specific application.

How are welded steel pipes made?

Seamless steel pipes are created by bending steel plates or strips into the desired shape and size, and then welding the seams together using various welding techniques. This process results in a pipe with a continuous, unbroken surface, which is strong and durable.

Welded Steel Pipe Applications

Welded steel pipe offers numerous advantages, making it a versatile and reliable choice for various applications. Some of its most common uses include:

1. Water and Gas Transport: Welded steel pipe is an economical and efficient option for transporting water, fluids, and natural gas over long distances. Its affordability makes it an ideal choice for large-scale projects.
2. Pipe Casing: In drilling operations, welded steel pipe serves as a stable casing, providing support to the hole during construction. It can be used as a temporary or permanent solution, depending on the project's requirements.
3. Bearing Piles: Welded steel pipe can be driven into the ground to support heavy structures and carry large loads. When used as bearing piles, it can be filled with concrete to enhance its strength and durability.

Welded steel pipe can be utilized in various construction projects, such as combi walls, underground utilities, and structural sections. In combi walls, welded steel pipe serves as the primary support, working in conjunction with steel sheet piles to create a robust and durable structure capable of withstanding significant loads. In underground utility installation, bored and jacked welded steel pipe can be employed to facilitate the process by joining sections of pipe together to create a continuous structure. Finally, welded steel pipe can be used to construct large, open structures like cofferdams, offering uniform bending resistance in all directions and enabling it to support heavy loads across considerable lengths without buckling.
