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.
