What is the material of the gasket for the flange of containers used to hold liquid ammonia?
Thread Content
The gasket materials used for sealing the flanges of containers that hold liquid ammonia include metal-wound gaskets, PTFE gaskets, and graphite gaskets. I wonder if anyone is aware of other gaskets made from single substances (with high purity) that can be used to seal flanges handling liquid ammonia?
