China CNG Gas Cylinder manufacturer, CNG CYLINDER

DSW Industry supplies compressed natural gas (CNG) cylinder solutions for vehicle fuel systems and compatible high-pressure gas storage applications. Available cylinder designs include all-steel and composite constructions, with specifications selected according to the intended application, operating pressure, applicable standards, and installation requirements. We support OEMs, fleet operators, and industrial buyers in evaluating cylinder capacity, working pressure, dimensions, and applicable certification requirements.

CNG Cylinder Types

CNG cylinders are classified into four main types according to their construction:

Cylinder Type Construction Main Characteristics Typical Applications
Type 1
All-metal		 Seamless steel cylinder with no composite overwrap. Robust metal construction; generally heavier than composite designs. Commercial vehicles, buses, and compatible stationary storage systems.
Type 2
Hoop-wrapped composite		 Metal liner with composite reinforcement wrapped around the cylindrical section. Composite reinforcement reduces weight compared with an otherwise comparable all-metal design. Vehicle fuel systems and other approved high-pressure gas applications.
Type 3
Fully wrapped metal liner		 Metal liner, commonly aluminum, fully wrapped with composite reinforcement. Reduced weight through full composite reinforcement while retaining a metal liner. Weight-sensitive vehicle fuel storage and approved transport applications.
Type 4
Fully wrapped composite		 Non-metallic liner, typically polymer, fully wrapped with composite reinforcement. Lightweight construction and strong resistance to liner corrosion. Suitable vehicle fuel systems and other applications covered by the applicable approval.

The appropriate design depends on the required storage capacity, operating pressure, weight limits, installation space, and intended application. For vehicle fuel systems, ISO 11439 may be an applicable standard; confirm the required standard and approval for the selected model and destination market.

Applications

CNG cylinders are used in vehicle fuel systems and high-pressure gas storage applications, including:

  • Buses and public transport: Vehicle-mounted CNG fuel systems.
  • Heavy-duty trucks: Fuel storage for commercial transport vehicles.
  • Commercial vehicles: CNG systems for compatible vans and fleet vehicles.
  • CNG refueling stations: High-pressure cylinder banks and cascade storage systems.
  • OEM projects: Cylinder integration for vehicle manufacturers and system integrators.

For transport requirements involving larger compressed natural gas storage assemblies, refer to our industrial gas supply systems information to explore related gas storage and distribution requirements.

Selecting the Right CNG Cylinder

Before selecting a cylinder, confirm its rated working pressure, water capacity, dimensions, material, valve connection, installation requirements, and certification documentation. Vehicle applications also require compatibility with the vehicle design and its approved fuel system. Actual specifications and available configurations should be verified for each model.
