[MW:8572] WELD JOINT QUALITY FACTOR FOR SAW PIPE AS PER B31.3

Hi,

Is it possible to increase the joint quality factor of SAW pipes?

As per B31.3, joint quality factor for SAW pipes is 0.95, but  the code has not mentioned anything about increasing this joint quality factor to 1 by any additional testing.

Could you please provide me any reference from the code or its interpretation  which permits to increase the joint quality factor by carrying out 100% RT.

Regards

Syed Moin
