Piping Material Specification Line Class check

Piping Material Specification Line Class check

Piping Material Specification Line Class check

(OP)
I am looking for tips on how to proceed with checking client "Piping Material Specification Line Class".  I understand that everything must of course be rated for the appropriate Press/temp, necessary components to fit-up, etc...  Essentially, I am looking for advice from someone who has done this on what has worked the best for them. i.e. order of operations to insure all components needed are included, everything passes temp/pressure ratings, branch table is within code etc...

RE: Piping Material Specification Line Class check

1.  Know what you're checking for.
2.  Make a procedure that will work for you.
3.  Stick to that procedure.

Haphazard checking will lead to mistakes.

RE: Piping Material Specification Line Class check

Why develop and check new Piping Line Classes ?

Process Industry Practices (PIP) have them for sale.

Let me guess..... your client has copied Line classes from someone else, but, of course, does not want to take any kind of responsibility.

They were transmitted to your boss....your boss has an MBA and does not understand what they are.

Therefore, you were assigned to "check" them (read here: responsibility dump)

(OP)
The specs are modified PIP specs.  Modified to suit client's preferences.  Additionally, I have found mistakes (unless I am calculating incorrectly) in PIP's specs.  Particularly, the use of S-STD 2" CS pipe w/ 0.125" C.A. which fails the B31.3 pressure design calc for wall thck @ full flange.
