Re: [MW:32076] SMALL DIAMETER PROCEDURE QUALIFICATION AS PER ASME SEC IX

I think you are complicating your life more than necessary, to do the bending and tension tests that your PQR needs per ASME IX requirements, you can use a tube of greater diameter and thickness of the same P number or if you like the same material, that will allow you to do your tests without any problem or setback, that is completely valid and design and write your WPS according to: thickness (0.89mm) and small diameter (6.35mm), your laboratory tests do not have to be strictly under these parameters: thickness (0.89mm) and small diameter (6.35mm).
Greetings!.

Dear Experts ,

PQR is to be qualified for
6.35 mm OD X 0.89 mm thickness
Welding Process - Autogenous Fusion - GTAW Orbital WELDING
Code - ASME SEC IX
Material - SA 213 TP316L
Tensile test - 2nos
Face bend test - 2nos
Root bend test - 2nos
Full section tensile test is carried out and found satisfactory

Bend test samples can not be prepared due to less thickness(0.89mm) and small diameter (6.35mm). Pipe Sectioning as per permitted by ASME for small diameter is tried but could not do it .
When tried to cut into sectioning for bending test piece preparation , pipe is getting bent and sectioning is not possible .
Experts , Pl. help how to go about bend testing or any other way forward
