Whether you need heavy-duty steel CNG cylinders for buses and trucks or lightweight composite CNG cylinders for passenger vehicles and advanced fuel systems, we provide engineered solutions built for durability, pressure resistance, and long service life.
What Are CNG Cylinders?
CNG cylinders are high-pressure vessels designed to safely store compressed natural gas. Natural gas is compressed to reduce its volume, making transportation and fuel use more efficient. Compared with gasoline and diesel, CNG offers lower emissions, lower operating expenses, and cleaner energy performance.
CNG tanks are widely used in NGV systems, refuelling stations, transportation trailers, and industrial gas storage projects worldwide.
Types of CNG Cylinders
| Type | Structure | Main Features | Typical Applications |
