NDT to check gasket in RTJ flange
(OP)
HIiiiiii....
Anybody ever used successful NDE technique to check the gasket in the RTJ flange during operation. I have concern if the gasket is CS in the SS piping.Please advice.

If you are worried about thermal expansion we use CS, really ARMCO Iron, in CS/SS and SS/SS flanges by the dozens.
About the only check we do when using RTJ fittings is check to see if the flange faces are parallel We make and break thousands of this type flange using a new gasket every year.

As rustbuster wrote, easy once you have broken down the joint.

tqvm for the information,really appreiate it... i have request the piping inspector to use CuCuso4 test to check the gasket whether it is CS or not in the SS RTJ flange (large size only), I dont know if this method is working or not since a bit difficult for the spray nozzle to reach the gasket for small size RTJ flange.Another option is to use pencil probe/small size magnetic tool but too difficult to get this kind of tool.
Anyway, I will give a feedback if it is working or not, worth to try it. Thanks

Unless specifically called out all CS gaskets re ARMCO Iron and with our supplier the SS gaskets are 316 SS, dead soft.
Can you post your specific problem??
