Piping A672 Gr C65 Cl22 Overlay Cladding
Piping A672 Gr C65 Cl22 Overlay Cladding
(OP)
Colleagues,
By following:
B31.3, 323.4.3, d) to
ASME VIII Div 1, UCL 34, a) to
ASME VIII Div 1, Table UCS-56, Note c) 5)
May I conclude that, if an A672 GrC65 Cl22 pipe up to 32 mm wall thickness is clad by overlay welding, then it does not require another PWHT?
