Siddhagiri - Model DIN 17457 -Stainless Steel Welded Pipe

The DIN 17457 is basically austenitic Stainless Steel Tubes, which are subjected to special requirements. They are also subjected to technical delivery conditions.

Difference between Stainless Steel ERW Pipe & SS Welded Pipe

The SS ERW Pipe can be made of any ss grade and it is manufactured through the electric resistance welding procedure. These are made of steel coils of the grade, and the seam here runs parallel to the pipe. The SS Welded Pipe can be produced by any welding procedure. They are constructed from various grades of ss like ferritic, austenitic, duplex, and martensitic. They come with various crystalline structures and possess different mechanical properties.

Difference between LSAW, SSAW & EFW Stainless Steel Pipe

The primary difference between LSAW, SSAW & EFW methods of manufacturing SS Pipe is in their welds. While the LSAW pipe has longitudinal welds, the SSAW has spiral welds. The EFW pipes are shaped by seam welding or the rolling plate.LSAW SS Pipe is made from the Longitudinal Submerged Arc Welding procedure. Herein, the metal plates are rolled, and then they are welded using the submerged arc welding process. They are mainly used for pipes having big diameters.

Spiral Submerged Arc-Welding or SSAW SS Pipe is also known as HSAW or Helical SAW. This is because their welding shape resembles the helix. It has the same welding technology as that of submerged arc welding using the LSAW pipe. Electric fusion welding or EFW SS Pipe uses high voltage electricity in the process. It is passed through the given material so as to heat and melt it.

What is Eddy current testing performed by Stainless Steel Welded Pipe manufacturers?

Eddy current testing are basically performed by SS Welded Pipe manufacturers and suppliers which helps to detect surface flaws. It can easily determine if the given product surface has any potential issues like cracks.
