ASME – With or Without U?


We are often asked: do we need our ASME pressure vessel with or without U? I remember an Irish rock band once had a similar dilemma :-)

If your vessel is to be installed in USA, then definitely. In Canada, more than likely. In the Middle East, probably not. Client specifications can request U stamp but this is often a carry-over from US-based company specifications and not actually a regulatory requirement for the destination country.

The good news is, whatever your scenario, the team at Abbotts can help.

After a two-day audit at our factory with the ASME US-based inspection team, and with support from our colleagues at British Engineering Services, we’re fully trained and raring to go… give us a call today!
