Annealed Pickled Welded Stainless Steel Tube Large Diameter Steel Pipe ASTM A358 TP304 Class 1 Grade

Description:

Spezilla manufacture a wide range of industry standard sizes of welded stainless steel pipe. Our ASTM A358 primarily consist of the austenitic grades of 304, 304L, 316, 316L, in a size range from 8” to 30” NPS. Material is stocked in the annealed and pickled conditions. 

ASTM A358:

Eletric-Fushion-Welded Austenitic Chromium-Nickel Stainless Steel Pipe For High-Temperature Service and General Applications

This specification cover electric-fusion-welded austenitic chromium-nickel stainless steel pipe suitable for corrosive or high-temperature service, or both, or for general applications. The pipes come in five classes.

Class1:
Pipe is double welded by processes employing filler metal in all passes and are completely radiographed.

Class2:
Pipe is double welded by processes employing filler metal in all passes without radiography

Class3:
Pipe is single welded by processes employing filler metal in all passes and are completely radiographed.

Class4:
Same as Class 3 except that the weld pass exposed to the inside pipe surface may be made without the addition of filler metal.

Class5:
Pipe is double welded by processes employing filler metal in all passes and is spot radiographed.

Pipe Grades:

304,304L, 304H, 316, 316L, 316H, 321, 321H, 317, 317L, 347, 347H, 309, 309S, 310, 310S.

Available Sizes:

Any size can be provided but this process is usually used sizes of NPS 8’’ and upper.
