3" propane pipe cert??

admin

I have a propane company asking me to weld together some 3" sched 40 steel pipe and fittings. No problem. Done it before. They are asking for " the proper certs" for the job. But are unable, so far, to tell me what cert they want. Don't think my d1.1 will be enough. Any recommendations ?I don't mind sitting a test. But I'd like to do the right one!!G

Reply:My procedure is similar to gordfrasers.  I would test with 2" Sch 40 pipe since ASME covers you up to 2x the thickness of the test sample, but only down to that thickness.  You don't want to shortchange yourself.If you need the forms and someone to bend the sections, let me know.
Reply:My D1.1 covers me down to 2" dia. and .125" wall IIRC, sounds like it would fit your bill.  I tested on 6" sch80 Tig/StickHowever I wouldnt even think about doing the job unless they tell you exactly what cert they need, and get it in writing.  I would ask for a WPS, but from the sounds of it I doubt they would have any idea what your talking about.Have we all gone mad?
