How to design flanges for non-standard equipment
Thread Content
When the equipment flange is subjected to pressures greater than 6.4 MPa, how should custom-designed equipment flanges be created, and what considerations should be taken into account during the design process?
There are too few of these conditional factors; please upload the parts of your drawings that can be shared and list all the technical specifications, so that we can take targeted action.

Okay, thank you. Here’s the situation: I want to design a custom flange with a pressure rating of 9.4 MPa and a DN800 size. Could I use as a reference the standard flange with a pressure rating of 6.4 MPa and DN800 size, by adjusting parameters such as the flange thickness, bolt diameter and quantity, as well as the thicknesses of the larger and smaller ends of the flange? Will it be sufficient to conduct a check using SW-6?
Yes, try to refer to the structural dimensions specified in the standards.
