Spiral Welded Pipe Manufacturing Process

The spiral welding technique is one of the oldest and most effective techniques for pipe production. The process begins with the selection of steel coils, which are shaped into a spiral form and sent to a welding station. Through submerged arc welding, the edges of the pipe are welded and create a strong joint. After that, its sizing is done. The method is useful in making cost-effective spiral welded pipes.

Application of Spiral Welded 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.

what is spiral welded pipe?

Spiral welded pipes are made by rolling steel strips into tube-like shapes and welding the ends. 

The process involves forming the steel strip into a spiral shape and then welding the seam. This welding technique makes the pipe strong and reliable by keeping it even and continuous.

Spiral welded pipes are made by coiling steel plates into a spiral shape. Long weld seams are used to weld them together. This is different from seamless pipe and LSAW pipe.

SSAW Pipe VS LSAW Pipe

Both these pipes are the types of SAW (submerged arc welding) pipes. But their way of manufacturing along with structures are different. For SSAW pipes, the steel coils are shaped into a spiral form, which results in a helical seam. While LSAW pipes are manufactured by bending steel plates into a cylindrical form, and then they’re welded. This makes them a great option to be used for high-pressure applications. Both these types of pipes are effective, and are used for the transportation of oil and gas.

SSAW Pipe

  • Cheap option
  • They’ve a spiral shape
  • Highly efficient
  • The outer diameter spans from 20 inches to 100 inches
  • Mainly used in construction
  • Tthickness tolerance is moderately precise

LSAW Pipe

  • Expensive compared to SSAW pipes
  • Welded longitudinally
  • Production efficiency is quite low
  • Outer diameter ranges from 16 Inch To 60 Inch
  • Used for medium/high pressure applications
  • Thickness tolerance moderately precise
  • High geometry accuracy
