The Company has researched high-pressure large-capacity gas cylinders for ships for more than 20 years, accumulating rich experience in design, research, development and production. Relying on the research results transformation of high pressure (25MPa and 40MPa) cylinders, it has successively developed four series of products, namely, high-pressure gas cylinders, gas storage cylinder group, long tube trailers and hydraulic gas stations, declared 15 patents, with A1, B1, C2 and C3 manufacturing qualification. The products are mainly used for storage and transportation of compressed natural gas (CNG),as well as industrial gases such as hydrogen, helium, nitrogen,oxygen and hydrogen chloride. At the same time, based on the requirements of different customers for special gas cylinder products, trial-production can be conducted rapidly to meet the diverse needs of customers.　　The Company has achieved strategic cooperation with many domestic gas cylinder design units, steel pipe manufacturing enterprises and users. As leading the development of domestic high-pressure gas cylinder technology, it has successively developed series of products such as high-pressure gas cylinders for ships, long-pipe trailer gas cylinders, high-purity gas cylinders and tube bundle containers.　　The Company has obtained 1 national defense invention patent,with 2 filed, and has applied for 6 invention patents, with more than 30 technical reports.
