Hello, I would like to invite you join to discuss the topic.
- Pressure vessel P-Number 1.
- PWHT is required.
- Acc. to ASME VIII Div. 1, Do we apply PWHT for attachment welds (temporary welds)?
- In case of ASME B31.3 apply, Do we preheat at 95 deg. C alternative PWHT? or 100% MT for weldment?
- Where can we refer to answer both questions?
