Why Do Sealing Gaskets Fail at High Temperature |
| |
| Abstract: | In view of the leakage problem of piping flange gaskets, after studying the mechanical and sealing properties of gaskets at high temperature, the paper presents an analysis of the gaskets' sealing failure, based on which a basic rule of sealing behavior under high temperature of gaskets is being submitted, which may serve as a reference for choosing proper sealing pipe sealing elements operating at high temperature as well as a guide for managerial and maintenance work. |
