High-Pressure Cryogenic Seals for Pressure Vessels
Large high-pressure vessels designed for ambient or high temperatures are not presently capable of containing gaseous helium at equivalent pressures when at cryogenic temperatures. Problems associated with achieving and maintaining high pressures at cryogenic temperatures as they involve seal designs were studied. The purposes of this study were (1) to identify suitable materials and develop a seal for cryogenic applications at pressures to 4080 bars (60,000 psi)* and (2) to identify some factors that affect seal performance and reliability for cryogenic pressure vessels. To accomplish this, the seal study was divided into three phases; 51 seal configurations were tested.
