Thin cover of corrosion-resistant steel (CRES) protects metal bellows and ducts against hydrogen embrittlement. Bellow current carries hydrogen at high pressure and currently is used in the engine of Space Shuttle.
Extensometer using ultrasonic pulse reflections to measure elongations in tightened belts and studs is much more accurate than conventional torque wrenches in application of specified preload to bolts and other threaded fasteners.
Thin copper electrodeposited layer protects metal parts in environments with which they may be incompatible. Originally developed for main engine of Space Shuttle where high strength nickle alloy bellows must operate in high-pressure hydrogen, technique protects nickel and is unaffected by forming process or subsequent heat treatment and preinstallation processing.
