A seal is affected by compressing the gasket material and causing it to flow into the imperfections on the gasket seating surfaces so that intimate contact is made between the gasket and the gasket seating surfaces preventing the escape of the confined fluid. Basically there are four different metho......

There are two major factors to be considered with regard to gasket seating. The first is the gasket material itself. The ASME Unfired Pressure Vessel Code Section VIII, Division 1 defines minimum design seating stresses for variety of gasket materials.

In the present seal, metal spiral wound gasket with excellent elasticity, high temperature, high pressure,low temperature and other characteristics, has become a very wide range of applied seal. Especially suitable for uneven loading, relaxation and easy access together, cyclical changes in temperat......

Clean radius and straight cuts are achievable on gasket material with the proper tooling. Thinner types of gasket material require nothing more than sharp blades and hollow gasket cutters. Gasket material over 1/4-inch thick require specialized mechanical tools to create the precision cuts necessary......
