325mm Automotive CNG Cylinder

325mm Automotive CNG Cylinder

The 325mm automotive CNG cylinder is available in variety of types classified according to the cylinder capacity. To illustrate, we can offer 40L automotive CNG cylinder, 45L CNG cylinder, 50L cylinder, and compressed natural gas cylinders with capacity of 55L, 60L, 65L, 70L, 80L, 90L, 100L, and 120L. Each of them comes with different cylinder length and weight, but the same wall thickness. The wall thickness is uniform in 4.9mm, which can perfectly avoid gas leakage and ensure safety. The length of our 120L automotive CNG cylinder is 1695mm and the weight is 87kg. The length of our 90L steel cylinder is 1315mm and the weight is 68kg. More detailed specifications are given in the following specification chart.

Quality of the 325mm Automotive CNG Cylinder
The steel tubes for making our CNG cylinder are acquired from Xingcheng Steel Corporation. We determine chemical composition of incoming raw steel materials for our steel tube production, so as to ensure that only materials with qualifying properties are accepted as raw materials. In addition, other materials for gas cylinder production including glass fiber, resin constituents, and quenching liquid are also acquired from trusted manufacturers.

Appearance Advantage of the 325mm Automotive CNG Cylinder
We have made substantial investments in acquiring steel tube materials with uniform thickness. Uniform cylinder wall thickness, coupled with our unique slightly saucer-shaped cylinder bottom and neck design, allows for effectively reduction in cylinder weight. So, while being used on vehicles, our CNG cylinder can assist in reducing energy consumption.

Usage Instruction on the 325mm Automotive CNG Cylinder
Our steel cylinder is designed for compressed natural gas storage. Each cubic meter of CNG, after dehydration, desulfuration, and other treatments, should contain no more than 8mg of water and no more than 20mg of hydrogen sulfide.
