Hi all,
I am dealing with a condition to use 6.4mm corrosion allowance for class 1500 valves upto size 1.5".
However, I am unable to find corrosion allowance in ASME B16.34 or API 602 or API 600.
As per equation mentioned in ASME B16.34 MANDATORY APPENDIX VI for class 1500 valves, i.e. tm (1500) = 0.18443d + 2.54, Can this mean that 2.54mm is the corrosion allowance for these valves?
This is what my fellow colleagues are implying. But based on my understanding, I believe that this is the minimum requirement and corrosion allowance will be added to it afterwards.
Same goes for API 600 and 602. I know that API 600 wall thicknesses are on a higher side compared to ASME B16.34, but again it doesn't say that corrosion allowance is taken into consideration.
Please help with this confusion.
