[MW:32066] SMALL DIAMETER PROCEDURE QUALIFICATION AS PER ASME SEC IX

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
