Dear friends

Vendor has manufactured seamless pipe fittings SA 234 Gr.WPB like elbows (3" SCH 40, 90 degree) and reducers (6" X 3" SCH 40).

Dimensons have to be checked as per ASME B16.9.

The under limit on thickness mentioned is - 12.5%.

I would like to know the Over Limit on thickness for pipe fittings as per ASME B16.9.

Regards

Prem Nautiyal
