1. Bolt Stress (Gasket Seating) = Force per bolt (4) / Root Area of Bolt (3) = 12051 / 0.302 = 39,903 psi. This is the minimum bolt torque for a 6-inch class 150 flanged joint utilizing spiral wound gasket and ASTM A193 B7 bolts.Mar 6, 2021
Can Garlock gaskets be reused?
Reuse of Garlock Gasket Material It is not a recommended practice to reuse a gasket. A gasket's function is to conform to flange high and low spots when compressed, and its ability to reseal decreases after it is compressed.
What is Garlock material?
Garlock Gylon Is a family of flat PTFE gasketing materials. It is manufactured using a proprietary process that imparts unique physical properties, which are not obtainable through conventional manufacturing methods. Some of the Characteristics are: - Color coded for easy identification. - Superior sealability.
How do you calculate torque for a flange?

What is a Garlock Gasket?
Garlock's BLUE-GARD Style 3700 gasketing material is a compressed, non-asbestos gasket made from aramid fibers with an EPDM binder. These gaskets drastically lowers emissions levels, fluid loss, and energy consumption.
