Abstract

The airtightness of a detachable joint depends on the load on its sealing surfaces and is determined by the magnitude of the leakage of the sealing medium or its viscosity, where the value of the latter depends on temperature. When a gas is heated, leakage decreases, while when a liquid is heated, leakage increases. An analysis of the influence of temperature on the airtightness of detachable joints is presented and recommendations are given for reducing this effect.
