Welding procedures for wellhead welding

Welding procedures for wellhead welding

Welding procedures for wellhead welding

(OP)
Hi,
I just developed welding procedures for ASME B31 piping using ASME Section IX welding code, I'm preparing to develop the same for wellhead piping, valves which I know is API 6A. Is there a different welding code for those or will it also be covered by ASME IX as long as the filler metal and material spec requirements are met?

Thank you.

mysarah,

Specification for Wellhead and
Christmas Tree Equipment
ANSI/API SPECIFICATION 6A
TWENTIETH EDITION, OCTOBER 2010
EFFECTIVE DATE: APRIL 1, 2011

6 Welding — General requirements

6.3 Pressure-containing fabrication weldments for bodies, bonnets, end and outlet
connections, bullplugs, valve-removal plugs and back-pressure valves

6.3.2.3 Welding procedure qualifications
The following apply:
a) written procedure:
Welding shall be performed in accordance with welding procedure specifications (WPS), written and qualified in accordance with ASME, BPVC:2004, Section IX, Article II. The WPS shall describe all the essential,nonessential and supplementary essential (if required; see ASME, BPVC:2004, Section IX) variables.

6.3.2.4 Welder performance qualification
The following apply:
a) testing requirements:

Article III.

Hope that helps,

Thanks a lot Kiwi2671,
That means its jus the same as qualifying procedures for pressure piping under ASME IX, but the only difference if to know the material types/specs. and knowing the strenght of electrode that can serve those materials.

 

RE: Welding procedures for wellhead welding

I would recommend reading API-6A section 6. H2S service and hardness requirements/locations, impact testing per temperature class will affect your New WPS.
