Shell and Head Replacement - Design Calculations?
(OP)
When a head and attached shell section of a Section VIII vessel is being replaced it would seem that new design calculations would not be necessary assuming the replacement is like-for-like to the original in all details, e.g., material, thickness, and location of nozzles. State is Illinois
Opinions please?

RE: Shell and Head Replacement - Design Calculations?
I would verify if this repair is required to be done according to original code of construction or current code.
If current code is use, design formulas may have changed from the original construction and that would require re-calculations.
In general, codes have evolved allowing for thinner material.I would not take that for granted but if that is the case it could give lower minimum wall thickness thus far increasing corrosion allowance and lifespan of the vessels.

Just because the theoretical formulas for thickness requirements and corrosion allowances have changed, the actual properties of fluids, and the phyiscal relationships between materials have not.
