More than 300 layered pressure vessels (LPVs) are in operation at NASA facilities across the country. Gases such as helium, hydrogen, methane, nitrogen, and air are stored under high pressure in these LPVs and supply a variety of NASA test facilities like wind tunnels and engine test stands. The vessels vary widely in size and operate under a broad range of pressures and temperatures, but they all share one common denominator: age.
