[MW:3175] Re: Welding Issue

 API pipe wont have P number instead it has S number.
 
API 5l X52 is S-1 Gr 1 material so if you have a PQR for P1 material you are automaticaly qualified for this material.
 
If you are doing SMAW welding then you can use E6010 for ROOT welding and E7018 for fill up and capping.
 
note that API 5l X 52 is equivalent to ASTM SA 106 Gr.B
 
hope this satisfies your requirement.
 
thank you

Hello, I'm in need of your knowledge, I need to make a WPS and a PQR
to weld  two materials, both are api 5lx52 schedule 120 outside
diameter16", I cannot determine nor find the P number nor Group number
of this material.

I am also trying to determine what types of electrodes to use, wether
E60XX or E70XX if I'm not mistaken nor how many passes to make (I'm
thinking abot 6).

Thank you and hoping for a response
