The seamless stainless steel pipes used in the GDI and CNG fuel systems have high strength, high pressure resistance, and flexibility, and are important standards for ensuring the normal operation of the vehicle without leakage. Common brands commonly used in CNG fuel systems are Hoke, SSP, Parker, Swagelok, etc. The normal operating pressure of CNG fuel system is divided into 3000PSI (200bar) and 3600PSI (250bar). The high pressure seamless stainless steel pipeline is manufactured and designed with a burst pressure four times that of 3600PSI (250bar) at 70 degrees Fahrenheit to ensure the safe transportation of CNG fuel. . The material of seamless stainless steel pipe for fuel system is ASTM 316/316L, which has excellent corrosion resistance. KC-SCT can also provide other stainless steel pipes, such as duplex steel to ensure stronger corrosion resistance. The high-pressure stainless steel tubes are bright annealed, and the inner surface is smooth, clean, and free of impurities, ensuring the purity of the delivered fuel and increasing the service life of the engine. Pressure check: Before the CNG high-pressure stainless steel pipe is shipped, each pipe is tested for hydrostatic pressure 4000PSI (280bar).
