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.
