High Pressure Oil Tubes for Diesel Engine Galvanized Precision Tube , NBK Precision Steel Tube , Passivated Steel Tubes


High Pressure Oil Tubes for Diesel Engine

Production process:
Cold drawing bright heat treatment without oxidization 100%nondestructive testing inside flushing under the high pressure antirust oiling outer and inner surface.


Main Features:
high accuracy, excellent brightness, no oxidization on the outer and inner walls after heat treatment, high cleanness inside wall. The steel tube is able to stand high pressure. No deformation after cold bending, no crack after flaring and flattening . The complicated geometrical forming and machining can be realized.


Main Application:
to be used in hydraulic system, automobile parts and in the occasion where the high precision, brightness, cleanness and mechanical properties of the tube are required.
Standards: DIN2391, EN10305-1, EN10305-4 etc.
Steel Grade: St37.4, St35(E235), St45(E255), St52(E355),etc.
Outer Diameter: 4-60 mm
Wall Thickness: 0.5-8mm
