Diameter Qualiffication Range for WPS per section IX

[rafeeqmahadighar rahman]

Dear Experts,

 

Accordance with section IX does the Pipe diameter range is an essential variable for WPS?

for example the PQR coupon has qualified on 8" dia, does it qualify for all or 2 7/8" and above.   

appreciate your valuable input.

 

Warm Regards'

Rafeeq

Hi,

WPS can be qualified with either Pipe or Plate, and the qualified WPS can be used for both.

 

Thanks & Regards,

Hi Rafeeq,

Pl. refer to my earlier reply. WPS/PQR done on 8" dia. pipe qualifies all ranges of pipe diameters.

[John Henning]

Diameter is neither an essential, supplementary essential, nor nonessential variable for WPS qualification for common welding processes.   Therefore, any groove weld qualifies groove welds for all diameters for the WPS. 

 

Diameter is an essential for weldor performance qualification for those same processes.  (see QW-353 through QW-357)
