Pipe Vs Tube

Pipe Vs Tube

Pipe Vs Tube

(OP)
A supplier proposed in stead of 3" pipe SCH XXS CS API 5L Gr X60 a 3" Tube SCH XXS A519-4130. My question is: could a pipe be substituted by a Tube if the mechanical proprieties of the latest are acceptable?

RE: Pipe Vs Tube

You're the engineer.  Take a look at the reference cited and see if the specification meets your requirements.  You should be able to compare the API-5L Sched 60 XXS spec to the A59-4130 XXS spec to see if it will perform within your actual performance envelope.

RE: Pipe Vs Tube

ASK YOUR SUPPLIER FOR BOTH SPECS AND DECIDE ACCORDINGLY YOUR REQUIREMENTS

RE: Pipe Vs Tube

Uust reject it as, "Not as Specified".  Tell him to go out and bring back the right stuff ...as specified.

RE: Pipe Vs Tube

Not enough information to provide you with an answer.

RE: Pipe Vs Tube

P.S.  There's more to it than just material equality, for example, Pipe specs are for a fabrication process.  I also don't have that spec listed as approved in my copies of B31.3/4/8
