The CNG cylinder comes with an outer diameter of 267mm, and it is classified into two models with different capacity, length and weight, etc. The 267mm CNG cylinder is made of 34CrMo4 material and works under maximum pressure of 20MPa. The 40L CNG cylinder is designed with a length of 930mm, and the 60L steel cylinder has a length of 1320mm. Both types of 267mm CNG cylinders are characterized by light weight. 40L cylinder weighs 41kg, and 60L gas cylinder weighs 58kg.

Quality of the 267mm CNG Cylinder
In our CNG cylinder production process, we have found that the cylinder wall thickness will typically decrease by 0.3mm after heat treatment, internal polishing and external polishing. If the initial steel tube thickness is equal to that of desired cylinder wall thickness, the final cylinders will not have the necessary thickness after processing, which may result in hazards and dangers after long term use.
To avoid potential dangers, we begin with steel tubes with thickness 0.3mm thicker than the desired cylinder wall thickness for cylinder production. This helps guarantee our CNG cylinder quality.

Appearance Advantage of the 267mm 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 267mm CNG Cylinder
Filling of the CNG cylinder should conform to related local regulations and rules. It is forbidden to use our gas cylinder for holding mixed gas, other type of gaseous material and CNG not conforming to the requirement listed above. Prior to CNG filling, there should be an overall check of the gas cylinder performed by a qualified professional in gas filling.
