Fuel Injector Feed Pipe

The Fuel Injector Feed Pipe is a precision-engineered metal pipe used to precisely deliver ultra-high-pressure fuel, stored and stabilized in the common rail, to the injectors in each cylinder.

Product Advantages:
Cold Work Hardening and Heat Treatment: Multiple precision cold drawing processes enhance the pipe's grain density and strength. Subsequent heat treatment ensures uniform internal structure and eliminates stress.

Autoclaving Prestressing: Utilizing an industry-leading autoclaving process, water pressure far exceeding the operating pressure creates permanent residual compressive stress in the pipe's inner wall. This stress significantly resists tensile fatigue caused by high-pressure fuel, extending fatigue life several times.

Special Alloy Steel: We select alloy steel pipes with exceptionally high tensile strength and fatigue resistance, specifically tailored to the corrosive and pressure-pulsating characteristics of high-pressure fuel.

Strict Cleanliness Management: After all machining operations, our high-pressure pipes undergo multi-stage ultrasonic cleaning and high-pressure solvent flushing to thoroughly remove metal particles, oil, and impurities. All finished products undergo internal cleanliness testing (meeting stringent standards such as ISO 4406) using a professional particle counter before leaving the factory, and are capped and packaged in a dust-free environment.
