Does anyone know the standards for stainless steel flanges? Thank you
For flange design standards, ASME B16.5/B16.47; just choose stainless steel as the material
Pipe flanges – HG/T20592 includes stainless steel flanges as well
I’m not sure whether the poster is asking about the material standards for flanges or the dimensional standards Materials can be forgings or sheets: each has its own standards. HG/T20592 and HG/T20615 specify stainless steel flanges, which simply need to be selected based on the maximum allowable working pressure of the material ； The strength of the container flange can be calculated based on the dimensions specified in NB/T47021-NB/T47023.
The standard design for flanges is the same regardless of whether they are made of carbon steel or stainless steel; their shape remains identical, with the only difference being the material used
Pipe flanges shall be selected in accordance with HG20592 or HG20615； The equipment flange standards (NB/T47021~47023) specify flanges with stainless steel linings; if a fully stainless steel construction is desired, the dimensions can be determined through calculations based on the standard sizes (with adjustments possible).
Stainless steel is not specified in the standards for equipment flanges; it is necessary to calculate the flange thickness separately. The pipe flange standards specify the corresponding materials.
