CNG Cylinder

The Cylinder is used to store compressed natural gas (CNG) at a working pressure of 200-250 bar. It is fitted with a shut-off valve in case of gas leakage. The cylinders have a valve and Pressure Relieve Device (PRD) that must be installed very tightly. For this purpose, the cylinder is placed on a specially prepared bracket-clamp that will secure the tank to prevent it from turning, when the valve is being tightened during installation . Before installing the valve in the cylinder thread, 30 rounds of Teflon tape (or any gas sealing tape) must be applied for better sealing. The valve must be tightened with no greater force than 25 kgm. The cylinder should be placed in the same direction as the car axle

The Manual Safety Valve must be easily accessible, so that it can be closed without problems in case of a leak. On the same side on which the cylinder valve is placed, one hole has to be made in the lower part of the trunk, to place the ventilation nozzles. This hole will allow ventilation of any gas leakage from the cylinder valves. To achieve this, before connecting the high-pressure piping to the valve, a ventilation bag must be placed on it and on the ventilation tube on the high-pressure piping.
