Any given CNG device uses various connectors, one-way valves, isolation valves, and other fluid system components to help reliably deliver gas from the storage tank to the engine. Similarly, the filling station uses the same type of components to connect a larger storage device to the filling machine, where the end-user can fill the vehicle with air.

All these components must be able to deal with various practical challenges. These challenges include:

Higher pressure. The compression and storage pressure of CNG can exceed 4000 psi, so it is vital that all components can withstand high pressure without any leakage risks. Safety is of the utmost importance here-CNG leaks can be dangerous. In particular, the filling station must be completely trouble-free, because the end-user is filling the vehicle every day. High-quality components are required.

Thermodynamic challenges. In operation, the application of compressed natural gas also faces certain thermodynamic challenges. When delivered to the engine, CNG changes from a high-pressure storage state to a low-pressure storage state, and the gas temperature drops significantly. All components of the system must be able to withstand these temperature changes. Low-quality materials may expand and contract due to temperature fluctuations, which may cause leakage or other failures.

Chemical compatibility. The elastomer component in the CNG system plays an important role in reliable operation, and chemical compatibility must be considered when selecting materials.

Continue to vibrate. The joints and connections in CNG applications must be able to reliably withstand the repetitive and sustained vibrations associated with a moving vehicle. For these reasons, it is important to find a joint with excellent vibration resistance.

Driving corrosion. Although CNG itself generally does not cause metal corrosion problems, the system components on the vehicle usually have to deal with possible environmental factors.

To meet each of these operational challenges, we need high-quality components made with the correct alloy formulation to provide reliable performance, corrosion resistance, and sealing.
