[MW:9850] Groove design and bevel

 Dear All,

 

I have a query, kindly share your valuable knowledge on this subject.

 

1-As per ASME IX,  Table QW-253 and QW-256, groove design is non-essential variable for SMAW and GTAW welding.

2-As per ASME B31.3, Fig 328.4.2 and ASME B16.25 Fig 3 and 5 (also Para 3.1C), components having thickness above 22 mm shall have compound bevel.

 

I would like to know that if the requirements of ASME B31.3 and 16.25 as stated above are mandatory? Because as per SEC IX, it is non-essential variable.

What I have observed at site, all pipes and fitting above 22 mm thickness have compound bevel from manufacturer, but all bevel prepared at side are single bevel. Is this acceptable?
