CNG Cylinders Are Safe To Use Common Sense
Jun 05, 2017

Automotive compressed natural gas (CNG) is a high pressure, flammable, explosive gas. CNG car cylinders are used to store compressed natural gas high-pressure containers, with an explosion hazard. CNG cylinder users should understand the following safe use of common sense:

First, CNG vehicles put into use, the storage of CNG cylinders must be in the test cycle. CNG cylinders are tested every two years; the second inspection of CNG cylinders for operated taxis is valid for one year; CNG cylinders and accessories damaged in traffic accidents are required to be re-used to test cylinders; When the cylinder is found to have serious corrosion, damage and other defects that may affect the safe use, CNG Steel Cylinders the cylinder owners shall promptly send the cylinders to the statutory inspection unit for inspection.

Second, the car scrapped, the car at the same time scrapped gas cylinders. The scrapped cylinders and unqualified cylinders should be disruptive by the cylinder inspection unit.

Third, the competent departments should strengthen the management of gas cylinders technical records and cylinder users of the safety education and training.

Fourth, CNG cars should be taken to manage electronic tags.

5, CNG car drivers in each time before the car, the cylinder and its fasteners, CNG Steel Cylinders safety accessories, piping and connection parts for routine inspection.

6, CNG cylinders in the course of the use of safety accessories such as found, bottle valve, fusible alloy plug failure and other failures, the car should be moved to a safe place, timely notification or sent to the cylinder inspection unit or CNG car repair shop.

Seven, strictly prohibit the unauthorized installation of CNG cylinders, cylinder installation must be qualified by the cylinder to complete the enterprise. CNG filling station on the illegal installation of the gas cylinders shall not be inflated.

CNG cylinders in the use of the process, found that the amount of gas and the usual exercise mileage does not match, or exercise for some time, CNG cylinder pressure dropped significantly, to be vigilant, CNG Steel Cylinders timely check whether the leak. If there is serious corrosion, damage or safety of its suspicion, should be promptly tested;

CNG cylinder composite material layer is strictly prohibited scratches, bumps and acid corrosion, CNG cylinder and fastening belt and mounting bracket should be used between the isolation rubber pad and should be fastened, the wear and deformation of the rubber pad should be replaced. Cylindrical CNG cylinders pay attention to protect the wound layer intact, keep the surface clean, to prevent corrosion of chemicals; CNG Steel Cylinders do not put hard objects in the trunk, so as not to bumps, knock injury CNG cylinder appearance. Do not press heavy objects on the gas system piping;

Non-glare, corrosion and extrusion, CNG cylinders shall not be close to the heat source, shall not be exposed to sunlight, and open fire distance should generally not less than 10 meters, CNG cylinders shall not impact;

CNG cylinders should be used in the back box as little or no electrical components, if necessary, it should also have explosion-proof performance, and as far as possible installed in the far away from the CNG cylinder parts.

CNG cylinder and inflatable valve, CNG Steel Cylinders pressure reducer easy to leak the interface should always check;

CNG cylinder valve is frozen, it is strictly prohibited to use fire baking. It is strictly prohibited to use more than 40 ℃ heat source on the CNG cylinder heating; is strictly prohibited in the CNG cylinder welding arc;

CNG cylinder and fastening tape and mounting bracket should be used between the isolation rubber pad and should be fastened, the wear and deformation of the rubber pad should be replaced;

The following accident should be tested at any time:

(1) Accidents and CNG cylinders or vehicles are exposed to shock, overheating or confirmation by other means of damage;

(2) damage to the chemical;

(3) CNG cylinders are overpressured or damaged by cargo or vehicles;

(4) other abnormal circumstances, a natural smell (identified as non-pipeline leakage), unexplained gas pressure drop, abnormal sound, the installation of loose signs;

(5) CNG cylinders with stock or deactivation time exceeding one inspection cycle shall be inspected prior to commencement;

(6) other non-normal circumstances.

11, CNG cylinders in the use of the process found that the safety of accessories failure, failure: bottle valve, fusible alloy plug, leakage CNG cylinder valve switch failure, CNG Steel Cylinders the first car should be moved to a safe place, set the cordon, to be compressed natural gas release After the end, sent to CNG cylinder inspection unit or natural gas vehicle repair shop. Do not repair and replace attachments yourself.
