White galvanized steel tubes

When producing galvanized steel tubes, we utilize advanced technical processing and use a chemical liquid imported from Germany. Both the inner and outer surfaces of the high precision steel tubes can be galvanized, giving them a high homogeneity and an excellent rust resistant performance.
Zinc wall thickness 8-12um, and customized as per customer requirements. Salt spray test: common requirements- 80-120 hours, high requirements- 120-300 hours Cr+6 free, environmental type

Process Description

Using a high precision, fine drawn bright seamless steel tube as the steel pipe for galvanizing, the outer wall of the steel pipe is cold-galvanized, and both ends are covered for dust protection.

    EN10305-2 Welded & Redrawn Steel Tube

    • Precision in combination with a high quality surface finish are the features that characterise our fine tolerance steel tubing
    • ERW feedstock tubes are manufactured from specially prepared pickled, oiled and cold or hot rolled steel coil.
    • Resistance-pressure-welding Therefore, the weld is created from the base material without any filler material
    • The removal of the excess material, both internally and externally, is a key element in the manufacturing process and this is an in-house skill.
    • The cold drawing process occurs after annealing and raises the quality of the feedstock tube to vastly superior levels of tolerance, surface finish and final material mechanical properties.
    • In some instances the final finished product specification can be further fine tuned by further annealing. This is of particular interest in relation to products that are specifically manufactured to unique customer specifications.

    St 37.4 Black Phosphate Tube
    Synopsis of Process Routing: quality carbon steel → cold drawing → bright heat treatment without oxidization (NBK status) → nondestructive testing. In the wall honing and inside flushing under the high pressure→ plastic capping on both ends→Phosphating→Antirust oiling outside surface→Bundles

    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. bright black. Color is homogeneously distributed on the tube surface. The tube has good property of antirust


    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.

    A519 Seamless Mechanical Tube

    ASTM A519 specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties. The tubes shall be furnished in the following shapes: round, square, rectangular and special sections. Heat analysis shall be made to determine the percentages of the elements specified. If secondary melting processes are used, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. The tubing shall be coated with a film of oil before shaping to retard rust when specified

    Shock Absorber Steel Tube

    Shock absorber precision steel tubes are suspension components that are responsible for absorbing the impact of avehicle’s movements. Through the shocks, the vehicle’s bounce cycle is cut short. If the car encounters abump on the road, it will still bounce; however, the shocks will shorten its bounce so that the driver and passengers will hardly feel it.
