Dear All,
I have with socket weld ball valves (below 1″). These valves supplied with the nipple and already tested. Finally we want add the nipple with slip on flange. I aware that after joint the flange onto the nipple, PT have to apply on the weld for final inspection. Now my question is shall we re-testing the valve because joint the flange by weld?
Many thank for share your view.
Darmao.
