As special pressure vessels dedicated to the refrigeration industry, refrigerant cylinders are widely used in air conditioning refrigeration, cold chain logistics, industrial equipment supporting and other scenarios. Their manufacturing, inspection and export transportation must strictly comply with corresponding industry standards and safety regulations.

A complete standardization system is implemented for domestic refrigerant cylinders. Disposable non-refillable cylinders mainly follow the standard GB/T 17268-2020. Special refrigerant cylinders are also regulated in terms of material, technology and environmentally friendly coatings in accordance with the group standard T/ZZB 0844-2018. Refillable cylinders comply with relevant specifications of GB 5100, while abiding by gas cylinder safety supervision regulations and special equipment technical requirements to ensure safety during factory delivery and subsequent use.

Refrigerant cylinders for international export need to meet EU standards such as EN ISO 11118 and EN 13322, as well as certification specifications including US DOT, South Korea KGS and RoHS. From raw material selection, welding technology, hydraulic pressure test and air tightness inspection to marking spraying, all production procedures are strictly implemented in accordance with unified standards.

Formal manufacturers strictly abide by all industry standards and control every production and inspection procedure, ensuring the pressure resistance, tightness and safety performance of refrigerant cylinders. The products meet procurement and import & export trade demands of various industries at home and abroad.
