Gasket Seating Stress

[nazem]

Please help me to find out the following information relating to the Dome Gaskets (SPIRAL WOUND GASKET WITH TEFLON FILLER TYPE WITHOUT INNER RING)

• The maximum assembly gasket stress (Sgmax)
• The minimum gasket seating stress (Sgmin-S)
• The minimum gasket operating stress (Sgmin-O).
• The gasket relaxation fraction (g)
• Gasket Sealing Inner Diameter 1226 MM
• Gasket Sealing Outer Diameter 1266 MM
. Gasket Centering ring O.D = 1305 MM
. Sealing Thickness = 4.5MM


I look forward to hearing from you

This information should be sought from the Gasket Manufacturer since it is Manufacturer dependent.

Dear DSB123, is there any calculation methods/formulas to find out those?

Hi nazem,
Spiral wound gaskets are Manufacturer specific and the seating stresses are particular to the Manufacturer. You need to get the information from them.
