expansion joint failure
expansion joint failure
(OP)
We have recently had some failures on EPDM expansion joints in Hot water systems. We are running below rated temp and pressure for the joint, and are still seeing failures. I have talked to some other companies about this and they too have had this experience. Does anyone out there have similar experiences or suggestions? It appears as if we will be going to metal bellows type to replace all installed.





RE: expansion joint failure
First you may need to check that the expansion joints were properly installed; alignment as well as spacing between pipes. This will ensure stress free expansion joints. Secondly check for compatibility with the atmosphere and operating conditions in which the joint functions.
That should get you started.
