    Section of Clean Energy Storage and Transportation Equipment

    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.
