CNG Composite Cylinders
CNG-2 cylinders, also known as Type 2 CNG composite cylinders, are a type of compressed natural gas (CNG) storage solution used in vehicles. These cylinders are designed with a steel or aluminum liner and are reinforced with fibers through a process called "hoop winding." This construction offers a balance between weight, cost, and performance. Key Features and Specifications Materials and Construction Liner Material : Typically made of steel (30CrMo or similar) or aluminum. Reinforcement : The cylinder's barrel is reinforced with long fibers (fiberglass or carbon fibers) impregnated with resin using a hoop winding technique. This reinforcement provides additional strength and reduces overall weight compared to all-steel cylinders. Manufacturing Standards : CNG-2 cylinders conform to standards such as ISO 11439:2013, GB/T 24160, and ECE R110, ensuring high safety and performance. Technical Specifications Internal and External Diameters : Examples include an internal diam...
