For non-standard quick-opening arch-type manholes (refer to HG/T 21527), how is the strength verified?

2017-03-15View Original

Thread Content

The largest quick-opening arch-shaped manhole specified in HG/T 21527 is only 500 in size. For a Class 1 vessel under internal pressure (less than 0.6 MPa), it is necessary to design a custom quick-opening arch-shaped manhole based on the structural principles outlined in HG/T 21527. How should the thickness and strength of such a manhole be verified? Is it to calculate by selecting a certain flange model using SW6? What is the basis? I would appreciate the guidance from all experts. Thank you!
