R stamp requirement for Exchanger
R stamp requirement for Exchanger
(OP)
Dear friends...
we Had one tubular heat exchanger with the partition plate passing and the procees is directly passing from inlet to out let(First pass- Fourth pass.It was identified as the partition plate on the head is not having enough length to hold the gasket and there is gap observed with partition plate face and gasket. The exchanger is designed in accordance with ASME VIII DIV / TEMA .
1. For the weld build up on the partition plate surface, R stamp is required or not?
2. Partition plate is coming under the pressure boundary or not?
3. On exchanger normally what type of repair required R stamp?
Please share your ideas which will support to resolve the issue.

Even though still I had some doubt.As I understood, repair carrying out on the pressure part only we required R stamp, So how we can correctly define the pressure boundary.
What about Tube plugging or re tubing which will comes under the R stamp requirement or not?
