ASTM A358 Pipe
ASTM A358 / A358M is standard Specification for Electric-Fusion-Welded Austenitic Chromium-Nickel Stainless Steel Pipe for High-Temperature Service and General Applications
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. The pipes shall be sorted into five different classes.
ASTM A358 CL1 - ASTM A358 Class 1 Pipe shall be double welded by processes employing filler metal in all passes and shall be completely radiographed.
ASTM A358 CL2 - ASTM A358 Class 2 Pipe shall be double welded by processes employing filler metal in all passes, no radiography is required.
ASTM A358 CL3 - ASTM A358 Class 3 Pipe shall be single welded by processes employing filler metal in all passes and shall be completely radiographed.
ASTM A358 CL4 - Same as ASTM A358 Class 3 except that the weld pass exposed to the inside pipe surface may be made without the addition of filler metal.
ASTM A358 CL5 - ASTM A358 Class 5 Pipe shall be double welded by processes employing filler metal in all passes and shall be spot radiographed.
