Do you have gasket parameters such as m, y and E values, which is related to thickness and the type of material of insulating gaskets, for ASME VIII Div 1 flange calculations? I have asked several insulating gasket vendors, and they could not provide me anything but recommendation on bolt torque which will require a lot of assumptions to check the flange connection.

I understand some will recommend to use EN 1591 calculation method. This method requires more detailed parameters otherwise the calculation will be junk in junk out.

Thanks in advance and kind regards.
