Materials & Construction
Each CNG composite cylinder features a seamless aluminium liner fully wrapped with high-strength fiberglass or carbon fiber reinforced with epoxy resin. This construction results in fiberglass CNG cylinders or carbon fiber CNG cylinders that offer superior mechanical strength, high-pressure resistance, and excellent corrosion protection.
The Type 2 CNG composite cylinder is designed to safely store natural gas at pressures of 20 MPa or 25 MPa. It is manufactured using a 4130X seamless steel tube and complies with international standards including ISO 9809-1, ISO 9809-3, EN, and DOT. These cylinders are classified as high-pressure vessels for flammable and explosive gases, with automotive applications typically requiring a storage pressure of 20 MPa.
Lightweight Carbon Composite CNG Cylinders
DSW’s carbon composite CNG cylinders are precision-engineered using advanced carbon fiber construction. Combining exceptional strength with a lightweight design, these cylinders deliver superior performance, reliability, and longevity. They are ideally suited for demanding industrial, medical, and mobile applications where safety, efficiency, and portability are critical.
Applications of CNG Fiber Cylinders
These CNG fiber cylinders and DSW CNG cylinders are ideal for natural gas vehicles (cars, buses, trucks), industrial gas storage, and mobile refueling systems. Their lightweight CNG cylinder design makes them particularly suitable for NGVs, where weight reduction is critical for efficiency and safety.
