Quick Detail:

1.High pressure fuel tubing are made using the cold drawing process. Precision tubes are made from carbon steel from quality Bao Steel,XingCheng Steel,and HuaiSteel.
2. The tubes are high precision in tolerance,excellent surface brightness,no oxidization on the outer and inner walls after heat treatment,high cleanness of inside wall.
3. No deformation after cold bending,no crack after flaring and flattening.
4.Higher and stable working pressure.

Description:

Synopsis of Process Flow: using high quality BaoSteel: ST35, ST37, ST37.4, ST52.4, cold drawn, none oxidization heat treatment(NBK), none destructive inspection.
Applicable Standard: ISO8535-1 (steel tubes for high pressure fuel pipe in compression ignition engine), ISO0404-1992(technical requirements for steel and steel product) ISO6892-1984 (tensile testing for metal )
 
Main Features: High precision,excellent brightness,no oxidization scale, high cleanness inner surface, flushing the inner diameter, antirust oil painted. total impurity<1.5mg/m, maximun granule 8 degree(≤0.2mm), withstand high pressure, no deformation after cold bending, the complicated geometrical forming and machining can be realized.
 
color of the tube: gray with white. the tolerance for OD and ID: ±0.05, quality inner surface: Grade Q,work pressure2000 kilos, max testing pressure: 6000 kilos without deformation, 180 bending degrees without cracks.

Applications:

For high pressure fuel pipe in compression ignition engine, all technical requirements call reach the level of top international brand, be able to replace the imported tubes and reduce the cost for our customers.
