Power Piping Code Gas Piping

[1hammer]

Our company has welders with certifications per AWS Code.
We have seen in the new specifications that qualified welding procedures ,welders and operators in accordance with ASME B31.1, or ASME B31.9 as applicable, for shop and project site welding of piping work. We work on schools and commerical projects.
Does our AWS certs qualify, or do we need to get our ASME PP stamp and get our welders re-qualified.

AWS and ASME don't mix. However, you don't need to have a PP stamp to do B31.1 work unless you are fabricating Boiler External Piping, which I doubt you are. Get yourself a copy of ASME Section IX. It will tell you everything you need to know about qualifying welders and weld procedures.

We install new heating boilers for hospitals,schools,etc... We install sectional boilers, and packaged boilers (Cleaver Brooks, Columbia etc...) I was always told piping after the first valve off the boiler, you don't have to be certified.
Also, we do install gas piping (natural and LP) for food service equipment , boilers etc... Do we need PP stamp when welding gas lines.

There are no code stamping requirements for piping attached to a Section IV (H Stamp) Heating boiler. The Boiler External Piping I referred to above applies to Power Boilers only.

Since there is no stamping required, you can fabricate this piping even if you don't have a PP stamp as long as you have procedures and welders qualified to ASME Sec IX.
