Abstract |
The leak-proof properties of seals depend on numerous factors, some of which are relatively complex. This report presents the results of a study on the leakage behaviour of flat static joints, and more particularly of bolted manhole cover gaskets. Three series of tests were conducted: leakage behaviour as a function of bolt tightening procedures, using different types of gaskets and with the systematic change of compressive load per unit area. Findings show that the specific rates of leakage in the nine types of flat gaskets studied are influenced considerably by the type of sealing material, the conditions of use and by the mechanical properties of the equipment flange used. The report will help users select suitable sealing. |
