[MW:14742] Diameter Qualiffication Range for WPS per section IX

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'
