Developed based upon normal fuel injection tube, and increase the surface and mechanical condition to fit the common rail tube requirements. We have passed the test in WFIERI, German Felss Burger, USUI and other company and institute.
Delivery condition: Straight tubes before autofrettage or tube lines
Adopted oil to draw the tube which makes the surface smooth and inner surface can reach Q degree with granule weight below 1.5mg, size depth below 0.05mm.
Before autofrettage, the working pressure can above 800 bars. After autofrettage, working pressure can between 1800 to2000 bars, and burst pressure 9000bars to 10000 bars.
