Lead plated aluminum ring provides static high pressure seal for large diameter pressure vessel
Lead plated aluminum ring provides a positive static seal for a large diameter pressure vessel for use in a hazardous environment at cryogenic temperatures with high pressure fluid flow. This design can be used in high and low pressure lines of any diameter for any fluid, with appropriate material modification.

Dynamic captive plastic seal
Fluoroplastic material held captive between valve sealing surfaces of 16 to 125 rms microinches provides zero leakage to a high-pressure line at high cryogenic temperatures, when the plastic material is subjected to sufficient stress. This sealing technique makes unnecessary the use of superfinished valve sealing surfaces.

Development of biaxial test fixture includes cryogenic application
Test fixture has the capability of producing biaxial stress fields in test specimens to the point of failure. It determines biaxial stress by dividing the applied load by the net cross section. With modification it can evaluate materials, design concepts, and production hardware at cryogenic temperatures.

Fiber glass prevents cracking of polyurethane foam insulation on cryogenic vessels
Fiber glass material, placed between polyurethane foam insulation and the outer surfaces of cryogenic vessels, retains its resilience at cryogenic temperatures and provides an expansion layer between the metal surfaces and the polyurethane foam, preventing cracking of the latter.

Liquid oxygen-compatible insulation system
To provide insulation for tees, elbows, sumps, and valves that are used to pass or store fluids at cryogenic temperatures, individual parts are insulated in an environmentally controlled facility. It is desirable that such insulation be liquid oxygen compatible and be easily removable and reinstallable.

Strain compatibility tests for sprayed foam cryogenic insulation
Mechanical stress applied to foam-coated aluminum alloy specimens maintained at cryogenic temperature simulates actual use conditions of the foam insulation. The testing reveals defects in the polyurethane foam or in the foam to metal bond.
