Q) I have cryogenic liquid hydrogen and hydrogen gas in my process and having a really hard time controlling leaks from flanges. All the gaskets I have used don’t seem last very long before leaking and cannot be tightened any further. Do you have any suggestions for dealing with this kind application?
A) Cryogenic services and their respective gasses are very hard to seal with traditional gaskets like spiral wound or kammprofile gaskets. Because of the large temperature swings and small nature of the gas molecules a gasket needs to be designed for these conditions and we would recommend a gasket like our JG Gaskets system or the Revolution Gasket System. Both gaskets are ideally suited to deal with cryogenic flange connections and have extraordinarily low leak rates.
