What type of pipe fittings must be used in high-pressure CNG applications?

In high-pressure CNG applications, the use of forged steel stamped fittings is essential due to their strength and durability. Forged steel fittings are made through a process that involves shaping steel under high pressure, resulting in fittings that can withstand the high pressures associated with compressed natural gas systems.

These fittings exhibit excellent structural integrity and resistance to failure under stress, making them suitable for demanding environments where safety is a top priority. The ability to handle high-pressure scenarios without risk of leaks or ruptures is critical in CNG applications, as even minor leaks can lead to hazardous situations.

Other materials like plastic, copper, and aluminum do not possess the required properties for high-pressure applications. Plastic fittings can be insufficiently durable and prone to failure under high stress, while copper and aluminum do not provide the requisite strength or pressure rating needed for CNG systems. This focus on maintaining safety and integrity is why forged steel stamped fittings are the preferred choice for high-pressure applications in the context of CNG.
