Welding Pad plate after Hydrostatic Test
Welding Pad plate after Hydrostatic Test
(OP)
we have hydrotested a Heat Exchanger( 20" Dia) later on we welded a pad( fillet weld) on the shell to support a pipe.
Do I have to test the Exchanger again because of the fillet weld. Or if we do an NDT like PT ot MT will that suffice

However, if the vessel was hydrotested and the AI did not complete the data report for the vessel, it would need to be re-hydrotested.

You said, weld a pad to support a pipe. In my undestanding, there will be additional external load to the shell.
- What is the size/load of pipe to be supported by this exchanger?
- What is the welded plate thickness?
I do not know the code. However, in my company, we will not allow to weld the pressure vessel for pipe support (except special case).
