Custom high-pressure and low-pressure oil pipe production
Internal combustion engine fuel injection high-pressure oil pipes are designed according to strict boundary conditions. Our technical team optimizes specific parameters including pipe route, heading structure, pipe clamp fixed points, nut structures, and strengthening parameters.
We maintain a comprehensive incoming material inspection process. Our testing facility is equipped with spectrometers, tensile testing machines, endoscopes, hardness testers, roughness detectors, and metallographic analysis equipment to ensure 100% raw material qualification. Through advanced production lines and scientific process control, we deliver zero-defect products capable of withstanding harsh working conditions and high engine torque without fatigue cracking.
