Compression-ignition Engine High Pressure Fuel Pipe Series

Synopsis of Process Routing

Using German standard high-quality steel as raw materials, ST35, ST3.7.4, ST52.4, fine drawing, no oxidation and bright heat treatment (NBK state), and non-destructive testing.

Main Application

Automotive. The working technical indexes of the high pressure tubing series for compression ignition engine produced by the company can fully meet the standards of the international brand steel pipe, and can completely replace the imported tubing products, which can greatly save and reduce the cost for the majority of users.
Main Features
High precision
Good roughness on
the surface and high
cleanness of inside wall
No oxidization on the
outer and inner walls after
heat treatment
Outer diameter, inner hole dimension tolerance ±0.05mm, advanced inner cavity surface quality Q grade. The normal working pressure is 2000kg, and the test pressure is 6000kg undeformed. The cold bending of a rod with the same diameter as its outer diameter is 180 °, and its surface is smooth and crack-free.
The steel tube is able to withstand high pressure. No deformation after cold bending, no crack after flaring and flattening. The complicated geometrical forming and machining can be realized.
Color of tube:
Light gray belt white
