Auyan Gas Cylinder

  Application of NGV/CNG Application of NGV/CNG   1. Automotive natural gas can replace all liquid fuels in all applications and more, while the opposite is not possible. 2. Regarding land transport, there are cars, vans, scooters, motorcycles, tricycles, and all types of buses and trucks that use this fuel. 3. In addition, cranes, agricultural machinery, snowcats, airplanes, light aircraft, motorboats, ferries, and trains have been successfully propelled by NGV/CNG. AUYAN is one of the leaders in the Chinese new energy industry. The main products are industrial welded insulated cylinders,  hydrogen cylinders , vehicles, intelligent  LNG cylinders , storage tanks, LNG supplying systems, filling stations, and  gas stations . 

  Gas cylinder production process 1. Blanking of the inner and outer cylinders - rolling of the inner and outer cylinders - longitudinal seam welding of the inner and outer cylinders - flaw detection of the longitudinal seams of the inner cylinder. 2. Welding of inner tank head group - pair of inner tank head group - inner tank circumferential seam welding - inner tank circumferential seam flaw detection - inner tank pressure test - inner tank helium leak detection - inner tank flame baking and wiping - inner tank winding. 3. Outer head polishing—outer head assembly welding—outer cylinder flame baking and wiping—inner and outer gallbladder winding—bottle outer circumferential seam welding—bottle body interlayer leak detection—vacuum pumping equipment—bottle body polishing—valve group welding— Liquid nitrogen cold test - static evaporation rate.

  Characteristics of LNG vehicle-mounted gas cylinders gas cylinder 1. Economic advantages   The temperature of LNG is about -162 °C, the pressure is about 0.1 MPa, the density is about 423 kg/m3, and the volume after gasification is about 600-624 times that of the liquid volume. 2.5 times. The onboard gas cylinders of large LNG trucks can travel continuously for 1 000-1 300 km with one refill, which is very suitable for long-distance transportation. The 410L vehicle-mounted gas cylinder can travel 400-500 km continuously in urban areas with one refill, and about 700 km with one refill on expressways. It can be seen that compared with the existing CNG and LPG vehicles, LNG vehicles have greatly improved the driving mileage of vehicles. 2. Security   The ignition point of LNG is 650°C, and the explosion limit is 5% to 15%. After gasification, the density is small, and a slight leakage will immediately volatilize and diffuse; while the ignition point of LPG is 466°C, and th...
