Dear gr2vessels & JStephen :
I think both of you misunderstanded my question or maybe it wasn't clear and directed to the main point, the tank is already built and we are going to do the hydraostatic test after three days, from the first day of fabrication the manufacturer confirmed that fabrication will be according to ASME Sec. VIII, Div.1. after the complete of hydrostatic test and sending the tank for installation, the manufacture has to submit a certificate of compliance with ASME standard that shall include all information about tank, like grade of steel,thickness,pressure rate,coating, etc.... I looked through the internet and I found form U-3, SO what I need to know if you have any other form for certificate that comply to ASME or if we can use U-3 form ?
Thanks alot for your help
