temperature media. Company ProfileManufacturing and
Inspection of Cryogenic Valves:Strict manufacturing technology and
special equipment have been developed for the low-temperature
valves produced, and strict quality control has been carried out
for the processing of parts.After special low temperature
treatment, the rough machined parts are placed in the cooling
medium for several hours (2-6 hours) to release the stress, ensure
the low temperature performance of the material, ensure the
finishing size, in order to prevent the valve in low temperature
working conditions, due to the temperature change caused by
deformation and leakage.Valve assembly and ordinary valves are also
different, parts need to go through strict cleaning, remove any
oil, in order to ensure the use of performance.
ApplicationsApplications: gas liquefaction equipment, air
separation equipment;Natural gas liquefaction, storage and
transportation equipment; Liquid oxygen, nitrogen, argon, hydrogen,
carbon dioxide low temperature storage tank and tank truck;Pressure
swing adsorption oxygen and nitrogen production equipment.Applied
in energy, petrochemical, metallurgy, aerospace, nuclear industry,
railway, air separation, oxygen production, petroleum, chemical,
pharmaceutical, chemical fertilizer, electric power, urban
construction, metallurgy, petroleum, pharmaceutical, fo
