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.
