What is SSAW Pipe?

SSAW stands for “Spiral Submerged Arc Welding”. It is a type of steel pipe manufactured through a spiral welding process.

Unlike seamless pipe and LSAW pipe, SSAW pipes are made by coiling steel plates into a spiral shape and then welding them with long weld seams.

SSAW pipe for large diameters and a variety of applications, offering better weld quality and relative economy.

What is Spiral Welded Pipe

SSAW Manufacturing Process

The production of SSAW pipes using the spiral welding technique is one of the most efficient and cost-effective methods available. Typically, a helical submerged arc weld is utilized in the production of spiral welded pipe, which is made from steel coil. The configuration of spiral welded pipe mills enables a considerable degree of flexibility, which makes it possible to manufacture a broad variety of pipe sizes and wall thicknesses.

Application of SSAW Pipe

Due to its suitability for large diameters, pressure and corrosion resistance, SSAW pipe plays an important role in transmission and infrastructure projects in several industries Piling. Structural applications, water pipelines, slurry pipelines, dredge pipelines, and other types of pipelines are some of the uses for SSAW pipe.

SSAW Pipe And LSAW Pipe

SSAW Pipe and LSAW Pipe are both SAW (submerged arc welded) pipe types often utilized for oil and gas transportation. The process through which they are welded distinguishes them. Steel coils are spirally welded, like a helix, in SSAW, such that the coil (strip) takes on the shape of a pipe. The welding of LSAW pipes is longitudinal, which means that steel (hot-rolled coil plate) is rolled into a pipe and the seam is longitudinally welded.
