Dear Expert...

When I have production test on T-, Y- or K-Connection CJP Groove welds on Pipe 8" Sch 40 (8.17 mm. Wall thickness)

How many qualified range for pipe size and wall thickness in table 4.11?

Thank you very much in advance.

Best Regards,
BST.

Pipe 8" Sch 40 (8.17 mm. Wall thickness) is not covered by Table 4.11.
You either follow Fig 4.27 or Fig 4.28 where the pipe dimensions are given.

Thank you very much.

My question it mean in the sometime may no have choice in production test. Because, Pipe 8" sch 40 are mostly used in fabrication, I'm looking at table 4.11 and can not find the answer.

Thank you in advance again.
