Non-repetitive filling welding gas cylinders are divided into DOT, EC and GB three product series, which respectively meet the requirements of corresponding national regulations and standards, and have perfect quality management system and advanced large-scale production line; according to the different design pressure of the cylinder, it can be used to fill different media (mainly refrigerant series and nitrogen medium); According to the different use requirements of the market, cylinder handle design is divided into two types: ordinary handle and reinforced handle.
