Hydrostatic Test in Tanks designed to API 650
Hydrostatic Test in Tanks designed to API 650
(OP)
After change a nozzle in a existing atmospheric Tank, is mandatory to carry out a Hydrostatic Test???.
Around the new nozzle we can see shell deformation as a bulge that could input stress concentration in weld Joint between nozzle and the shell.
It is mandatory once we have detected the bulge or it is mandatory according codes API 650 / API 653 each time you replace a shell nozzle..?
Thanks a lot in advance

Now I disagree. Get a copy of the curent version of API-653 and read 3.20(a) and (b) regarding nozzle sizes that constitute a major repair/alteration that reequires a hydrotest.

I feel your understanding might be correct,but this could be the 'Optimum value'indeed!
