Automotive CNG Cylinder

  • 325mm Automotive CNG Cylinder The 325mm automotive CNG cylinder is available in variety of types classified according to the cylinder capacity. To illustrate, we can offer 40L automotive CNG cylinder, 45L CNG cylinder, 50L cylinder, and compressed natural gas cylinders with capacity of 55L, 60L, 65L, 70L, 80L, 90L, 100L, and 120L. Each of them comes with different cylinder length and weight, but the same wall thickness. The wall thickness is uniform in 4.9mm, which can perfectly avoid gas leakage and ensure safety..
  • 356mm Automotive CNG Cylinder The automotive CNG cylinder has an outer diameter of 356mm and wall thickness of 5.4mm. Made using 30CrMo, the 356mm CNG cylinder is durable and safe to use. According to the cylinder capacity, our 356mm automotive CNG cylinders are classified into a wide variety of types which all comes with varied length and weight. To illustrate, we can offer gas cylinders with capacity from 60L to 150L. Our 60L automotive CNG cylinder has a length of 800mm and weight of 54kg, our 70L CNG cylinder ...
  • 406mm Automotive CNG Cylinder We can offer 406mm automotive CNG cylinders with minimum capacity of 82L and maximum capacity of 200L. Each type of cylinder offers different length and weight. For instance, our 90L automotive CNG cylinder has a length of 910mm and weight of 76kg, our 110L CNG cylinder has 1075mm length and weighs 89kg, and our 145L compressed natural gas cylinder has a length of 1365mm and weighs 111kg...

The automotive CNG cylinder is manufactured under GB24160-2009 and ISO11439 standards. Made using superior quality seamless steel pipe and newly developed glass fiber, our automotive CNG cylinder has advantages like light weight, high bursting pressure, high usage safety standard, and long service life. Automotive CNG cylinders are ideal for compressed natural gas storage and for use in various CNG powered cars, coaches and multipurpose vehicles.

Due to our adoption of special cylinder forming technique, our automotive CNG cylinder is slightly saucer-shaped. This allows the cylinder to have larger capacity as compared with a traditional standard cylinder. That is, compared with a traditional gas cylinder with same capacity, our CNG cylinder offers shorter length.

The fine quality glass fiber material and scientific glue preparation provide our automotive CNG cylinder with improved aging resistance and surface smoothness. Meanwhile, we have made substantial investments in acquiring new type curing equipment to offer improved curing method. This curing method can effectively avoid resin loss during curing process and ensure the safe use of our automotive CNG cylinders. It also assures surface smoothness of the external winding layer around the steel CNG cylinder and avoids workers' injuries caused by the fine fibers of the glass fiber material.

When exposed to direct sunlight, high temperature and acid pollutants, etc., the glass fiber and resin utilized in the automotive CNG cylinder production may have accelerated aging. This may reduce the service life of automotive CNG cylinders. Also, when the CNG cylinder is mounted in the car truck, the external winding layer may be damaged due to its collision between the goods in the trunk. In order to avoid aforementioned damages to the winding layer, we have tailor-made a protective layer for our automotive CNG cylinder' winding layer, so as to extend its service life and make our CNG cylinder durable.

According to Chinese national and international related standards, an automotive CNG cylinder requires ultrasonic flaw detection. In our production and testing process, we found that ultrasonic flaw detection for gas cylinders can detect and find out the flaws on cylinder body but cannot detect any flaw at both ends of a cylinder. Therefore, we use high precision magnetic particle inspection equipment to give another round of flaw detection to our automotive CNG cylinders, so as to avoid cylinders with flaws at both ends caused by improper heat treatment and inconsistency in raw material quality.

As a professional automotive CNG cylinder manufacturer in China, our company offers 325mm automotive CNG cylinder, 406mm automotive CNG cylinder, 279mm CNG cylinder, 356mm CNG cylinder, and more.
