Calculation of circumferential stress under test pressure for folded conical heads
Thread Content
For the calculation of the circumferential stress under the test pressure for folded conical end closures, the formula specified in GB150 should be used. I appreciate your guidance. Thank you
By modifying formulas 5-8 in GB/T150.3, the calculated pressure is replaced with the test pressure, the calculated thickness is replaced with the effective thickness, and the allowable stress is replaced with the desired circumferential stress.
Agree with the second floor; reverse-calculate using the formula for thickness.
Thank you for the guidance. Which formula is used for external pressure? In 150.3, is it (5-18) or (5-19)?

Pressure vessels are subjected to pressure tests using internal pressure; the purpose of these tests is not to evaluate strength, but rather sealing performance. Stress verification generally poses no problems.
Thank you for your generous guidance{:1_90:}
