Hydrotest requirement for New Zealand
Hydrotest requirement for New Zealand
(OP)
Peers,
Pressure vessel constructed in US designed to ASME VIII Div 1 which specifies Hydrotest pressure 1.3xMAWP, does the local regulations in NZ require the vessel to be re-hydrotested to 1.5xMAWP according to AS1210 for registration?
Thanks

hmmm...AS1210 seems not been revised for more than a decade now! Is the 1997 the last edition and the original?
RE: Hydrotest requirement for New Zealand
Original..?? Let's not go there...And where is the new edition, claimed ready for issue 3 or 4 years ago...
Sorry...

gr2vessels has it correct. It has been a few years since I have done work in NZ, but I also remeber that seismic design requirements were fairly high and these need to be included.
I also remember that a hazard category needed to be assigned to the vessel and the level of inspection and design review was related to that category.
We had a small purchased vessel that was ASME Code stamped but the NZ Authorities did not recognize the AI (insurance company) so the hydrotest had to be re-done there and all the calculations, material certs, WPS/PQRs, etc had to be sent for their review.
Do your homework and get in touch with the locals. My experience is that they are very helpful.
btw. if you do any work in Australia similar requirements but there are variations between the states. I recently did vessels in NSW and Tas and there were differences in the requirements. So again, do you home work BEFORE you sign any contracts to build and make sure that the design satisfies the local requirments. I found WorkCover to be helpful during the process.
