Product Description

This page shows different types of CNG cylinder with **6mm outer diameter and 7.5mm wall thickness. In order to suit vehicles' fuel capacity demands, the **6mm CNG cylinder is classified into different types according to its capacity. With same outer diameter and wall thickness, our CNG cylinders are designed with varied lengths to allow increasing of cylinder capacity. The cylinder weight also varies accordingly. For instance, our *5L compressed natural gas cylinder has a length of **5mm and a weight of *9kg, our *5L CNG cylinder has a **5mm length and *6kg weight. The maximum capacity of **6mm CNG cylinder is **0L. More detailed specifications are given in the following specification charts.

Quality of the **6mm CNG Cylinder
According to Chinese national and international related standards, a gas cylinder requires only ultrasonic testing. However, in our CNG cylinder production and testing process, we found that ultrasonic testing is able to detect and find out the flaws and defects of the cylinder body but cannot detect any flaws at both cylinder ends. Therefore, we use high precision magnetic particle inspection equipment to conduct another inspection of our CNG cylinders, so as to avoid gas cylinders with flaws at the ends which can be caused by improper heat treatment or inconsistence in raw material quality.
