ISO 8535-1 Fuel Injection Pipes E235, E335, E215
Seamless cold-drawn single-wall tubes for high pressure fuel injection.
ISO 8535-1 Specifies dimensions and requirements for seamless cold drawn single-wall steel tubes for high-pressure fuel injection pipes used on diesel engines and for fuel injection pump testing.
Automotive tubes with standard ISO8535-1, material E235, E255, E355 etc. delivery condition NBK.
1.Precision steel seamless tubes for automotive industry are made using the cold drawing process.
- 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.
- No deformation after cold bending, no crack after flaring and flattening.
