SAE J529 engineering machinery high pressure fuel oil injector pipe
High Precision Seamless Steel Tube for Automotive Industry and Hydraulic Application

Priskribo:

Sinoptiko de Process Routing: Quality Carbon steel — Cold Drawn — Heat Treatment Without Oxidization (NBK Status) — Nondestructive Testing— Flushing The Internal Hole With Special Equipment Under The High Pressure —Dealing With Antirust Oil On Surface — Plastic Capping On Both Ends.

The raw material we choosing:high quality Bao Steel,XingCheng Steel and HuaiSteel.Physical and chemical inspection will be made to make sure each batch is in qualified range. After piecing,each piece of tube is checked to be in permitted size deviation,this can garantee higher thickness tolerance and concentricity.

Production process quality control: We use the domestic first-class drawing machine,the production process is controlled with high hardness alloy internal and external matrix,so the product dimensions tolerance and ovality are strictly controlled in high level.Through the first, middle and last process inspection to ensure product quality.

Inner and Outer Surface Cleaning: We adopt automatic inner surface cleaning machine, rotating brush cleaning and high pressure oil flushing to clean the inner and outer surface.The new steel tube production craftsmanship can effectively remove all particulate attached to the inner and outer surface of tubes and thus achieving the utmost surface cleaness and polishness.

Finished tube anti-rust oil plating: We adopt high pressure spray plating method, the antirust oil is plated by high pressure jet after ten passes of filtering and one pass of precipitation to safeguard the tubes’ outer and inner surface cleaness and polishness.
