Pipe Thickness Calculation for Internal Pressure - Make urea stainless steel pipe pressure testing

Corrosion allowance for wrought steel pipe (CS, LAS LTCS) is mostly taken 3 mm and zero mm for stainless steel pipes. Corrosion allowance is not fixed for all the cases, it may vary from line to line and from project to project. Mill tolerance for the seamless pipe is 12.50% and 0.3 mm +/- for the welded (ERW or EFW) pipe. Abbreviations Proof Test/Burst Test, Pneumatic Hydrotesting for Pipe urea stainless steel pipe pressure testingTo qualified the design of the pipe fitting, manufacturer performed a various test including burst test to ensure that design will meet the all the standard code requirements. In this test, a pipe fittings are welded and a dummy pipe spool is prepared. This pipe spool is then pressurized to pre-define calculated burst test pressure.
