Cryogenic processing is a fascinating and truly spectacular means to increase wear resistance & life on all metal and some plastics. Deep cryogenics is the ultra low temperature processing of materials to enhance their desired metallurgical and structural properties. The cryogenic process is not a surface treatment. It affects the entire mass of the part, making it stronger throughout and dramatically reducing wear. The process keeps working for the life of the tool rather than ceasing to be effective after the surface is worn. Grain structures are closed by the process resulting in a larger contact surface area that reduces friction, heat and wear.
Cryogenic safety relief valves are designed for use with cryogenic and industrial gas equipments. It is suitable for pressures to 400 psig and temperatures from -423 to +400°F. Its application includes stationary cryogenic storage tanks, dual safety relief systems, and air and gas compressors for overpressure relief of tanks, pipelines, and pumps.
