The LNG vehicle gas cylinder is a low temperature storage tank, which mainly adopts a double-layer structure. The inner tank can withstand a certain pressure and is used to store and supply low-temperature liquid liquefied natural gas. The outer shell is the protective layer of the inner tank, and a certain distance is maintained between the inner tank and the inner tank to form a thermal insulation space, which can withstand the gravity load of the inner tank and the medium and the vacuum negative pressure of the thermal insulation layer.

In order to meet the large demand for LNG vehicle gas cylinders in the market, Huaheng Company has designed a new automatic production line according to the production and manufacturing requirements of LNG vehicle gas cylinders: shearing plate→rolling automatic loading and unloading system→logistics system→head Grouping system → automatic welding system → winding and nesting system → automatic flow polishing system, which greatly improves the production efficiency.
