Welded Stainless Steel Pipe Specifications

Stainless Steel Welded Pipe Specifications

ASTM A 240

 This specification covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications.

ASTM A312 

This specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.

ASTM A 358

 This specification covers electric-fusion-welded austenitic chromium-nickel stainless steel pipe suitable for corrosive or high-temperature service, or both, or for general applications.

ASTM A 778

 This specification covers straight seam and spiral butt seam welded unannealed austenitic stainless steel tubular products intended for low and moderate temperatures and corrosive service where heat treatment is not necessary for corrosion resistance.

Welded Pipe

When selecting a seamless or welded pipe, an abundance of facts should be taken into consideration.

Stainless steel pipes can be manufactured in both seamless or welded forms. The decision whether to use a seamless or welded pipe depends principally on the wall thickness / diameter ratio and the specified pipe tolerances. For the individual production of welded pipes, the raw materials can be ordered and used in precise thicknesses depending on the wall thickness calculations, which will deliberately save resources and cut costs.

Welded pipes are more advantageous for small, medium-sized and large outside diameters with wall thicknesses of between 2 and 70 mm.

Type of Stainless steel welded pipe in our Inventory:

Pipe Lengths and Quantities

For welded pipes, the pipe lengths can be freely selected up to 12 m or 18 m without circumferential welds. The minimum production batch for pipes made from coil depends on the length of the coil for special alloys or sizes. With production from individual steel plates, small quantities may also be provided.
