How to determine the thickness allowance for components in pressure vessel design
Thread Content
Hello, everyone! The leader assigned a task, asking me to create a set of unified regulations. It shouldn’t be the case that everyone uses different tolerances for the same things. For example, how should tolerances be set for the thickness of cylinders and tube sheets, for the area of bolts, for the thickness of flanges, and so on – how should all these tolerances be determined? Also, is there a criterion for determining how much margin to consider? For example, if the calculation yields 99, is it okay to allow 100? To write a rule, does it have to be calculated so that it doesn’t exceed 95? I was wondering if there are such regulations in the departments where you work on a regular basis?
At least 15% allowance should be provided for the tower foundation bolts
