Weldolet Material
Weldolet Material
(OP)
Situation is as follow and would appreciate some advice:
Existing pipe was originally designed for >1000F operation and material is P22. After some modification to the system, the new operating condition is reduced to 500F@450psi. Now if I need to add a branch to this system, would it be acceptable to use a CS weldolet (instead of P22) for connection?
Thanks in advance.

These are acceptable under the piping codes and can be made for a weldolet....but it is bad practice if othet alternatives are possible.
I suggest that you find a P22 weldolet....they are out there.
BTW, BigInch... I believe that your recollection is in error..... B31.1/31.3 allows carbon steel piping materials to ~775F in continuous duty.

Thanks for the input. Would you mind explaining why it would be considered as a bad practice? Thanks.
