The ASTM A105 is the Standard Specification for Carbon Steel Forgings for Piping Applications. It will tell you everything you need to know the standards.
Cast iron, SS, Mild Steel
By knowing the availabe pressure and the diameter / material of the piping
what is piping specification ?
d2a is a pipe class and a1a is the piping materials
It depends on the specification.
piping inspection means checking pip line with rules and specification( according to P & ID drawing )all item included and completed 100 % proper line to plan
