Buckles on API 650 tanks 8(
Buckles on API 650 tanks 8(
(OP)
I am looking for tolerance figures for buckles on the surface of the finished tank. They do not look nice and I have to convince the erection contractor that they are out of tolerance.. and API 650 does not help much.
Thanks in advance for any advice/guidance..

1/-Seals are important, probably seal maker can advise.
2/- This problem can be compared to pressure vessel under exteranl load , where one has to measure oyt of roundness at several sections of the vessel.
3/-API 579 in its section 8 , deals with deformations and misalignment and their criteria.
In its , 8.6 and 8.7 it summarizes equirements of: API 650, 653 (and even figure 8.5 anfd for API's 620 which is asimilar to ASME VIII)..
Have a nice day.

My opinion only.
1/-Seals are important, probably seal maker can advise on tolerances.
2/- This problem can be compared to pressure vessels under external pressure, where one has to measure the of roundness at several sections of the vessel.
3/-API 579 in its section 8, deals with deformations and misalignment and their criteria.
In its figures 8.6 and 8.7 it summarizes the requirements of: API 650, 653 (note also figure 8.5 for API's 620 which is quite similar to ASME VIII)..
