High Pressure Fuel Pipe Series

Compression Ignition Common Rail High Pressure Tubing
Our company implement Iso-8535 Standard to produce compression-ignition
common-rail high pressure fuel tube. The raw material SDY1800 is almost the
same as German grade DSG 1800, it is jointly developed by us and Baosteel. The
normal working pressure can be over 1600KG, 1800KG, the tolerance for OD
and iD can be + 0. 05MM, core quality can reach grade Q. Now we are the best
manufacturer in China.

Cold Drawn Seamless Steel Tube (polished)

Selection Standard: DIN2391( Germany Standard)or EN10305-1/4( Europe Standard)
Synopsis of 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.
Main Features: high precision, excellent brightness, no oxidization on the outer and inner walls after heat treatment, high cleanness of inside wall. 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: gray with white.
Main Application: to be used in hydraulic system automobile and in the occasion where the high precision, brightness, cleanness and mechanical properties of the tube are required.

DIN Black Phosphated Hydraulic Tube In High Precision

Synopsis of Process Routing: Cold drawn and bright NBK seamlee steel tube is used as the tube to be phosphated.
The phosphated is realized with the imported chemical fluid to form a black film. 
The antirust oil is absorbed by means of the micro pore on the film to prevent from the rust. The caps are covered at two ends of tube to prevent from the dust.

Main Features: color of steel tube: bright black Color is homogeneously distributed on the tube surface. The tube has good property of antirust.

Main Application: used in hydraulic system, shipment industry, nested card connector (pipe joints) with matching.

Main Material Mechanical Property:
The steel grades of raw material used in our company arc mainly ST35, ST37. 4(10#). ST45(20#), ST55(35#),CK45(45#) ST52.4(16Mn)etc. produced by Shanghai Baosteel Group.

The steel tube produced by our company has excellent mechanical property and performance in process. The steel tube is able to withstand the high pressure, impact and particularly suitable for application of hydraulic machinery and automotive fabrication. The tube can be cold bent at any angle. No crack will occur after flaring and flattening for the industry, which the bending and forming is required in process.

Percision Galvanized Steel Tube

Synopsis of Process Routing: DIN high precision cold drawn bright seamless
steel tube is used as the tube to be galvanized on the outer surface, caps are
covered at two ends of tube to prevent from the dust.
Main Features: Different color of Zinc such as white, yellow, army-green, black
on the outer surface, good roughness, antirust and antisepsis could improve
after Zinc coated.
Main Application: Automotive, military, rail way industry and other fields with high requirement of the tube’s brightness, cleanness, antirust and antisepsis.
