279mm CNG Cylinder

279mm CNG Cylinder

This page shows you our different models of CNG cylinder with the same outer diameter of 279mm. Our 279mm CNG cylinder is designed with 6.4mm wall thickness and is made of 34CrMo4 to ensure high strength and durability. It is able to work under maximum pressure of 20MPa. In order to suit customers' varied demands, we design our 279mm CNG cylinders with varied capacity, length and weight, etc. To illustrate, the capacity of our CNG steel cylinder ranges from 30L to 100L, and length ranges from 680mm to 1945mm, and the weight of our 279mm CNG cylinder is between 34kg and 92kg. For more detailed information, please refer to the specification chart for our 279mm CNG cylinder.

Quality of the 279mm 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 279mm CNG Cylinder
Although slightly saucer-shaped, our CNG cylinder has a smooth arc shape for its cylinder bottom and neck sections. The arc is almost the same for the cylinder bottom and the cylinder neck. The design not only allows the cylinder bottom and neck to bear higher pressure during operation, but also offers aesthetic appearance.

Usage Instruction on the 279mm CNG Cylinder
The CNG cylinder should be checked and tested thoroughly every three years, or given periodic checks and tests according to local regulation and rules. The checking and testing of gas cylinders should be conducted by qualified companies in the industry. It is forbidden to continue to use the CNG cylinders which have been seriously corroded, burned, impacted, or damaged by other reasons, so as to avoid potential dangers.
