Note 1: Selection of materials should be made with attention of temperature of service.
For such guidance specification A 20 / A 20 M may be consulted.
Class designates:
Section 1 the type of heat treatment performed during manufacture of the pipe:
all classes other than 10, 11, 12 and 13 shall be heat treated.
Section 9 whether the weld is radiographically examined:
the full length of each weld of classes X1 and X2 shall be radiographically examined.
Section 8.3 whether the pipe has been pressure tested:
classes X2 and X3 pipe shall be pressure tested in accordance with specification A 530 / A 530 M
