The Creep-Relaxation Properties of a Flat Face Gasketed Joint Assembly and Their Relation to Gasket and Flange Design 630191

A major problem facing the gasket industry today is torque loss. The fundamental relationship between gasket creep and torque loss is presented. Methods for the measurement of gasket creep are discussed. Mathematical formulas are also developed illustrating creep in a bolted joint assembly. Basic principles for developing rational flange and gasket design procedures are outlined.
Much research work remains to be done on gasket creep, and better instruments for measurements of pure creep, pure stress relaxation, and creep-relaxation must be developed.
