Industrial gas high pressure cylinder is a pressure vessel specially designed to store and transport compressed industrial gases such as oxygen, nitrogen, argon and hydrogen. Manufactured from alloy steel and aluminum alloy, it can bear high internal working pressure to store large volume of gaseous media. Equipped with valves, safety bursting discs and protective caps, it features good pressure resistance, air tightness and portability. Widely used in welding, metallurgy, laboratory, electronics and chemical industries for short-distance gas supply. Strict pressure inspection and regular testing are required to ensure transportation and usage safety.
