    Galvanized Square Steel Pipe For Steel Structure

    Galvanized square pipe is rolled by galvanized steel strip after technological treatment. Generally, galvanized steel strip is unpacked, leveled, curled and welded to form a round tube, which is then rolled into a square tube and then cut to the required length.

  • Cold Drawn Steel Pipe For Ecuador

    Cold Drawn Steel Pipe For Ecuador

    Cold drawn steel pipe is a kind of steel pipe, that is, it is classified according to different production processes, which is different from hot rolled (expanded) pipe. In the process of expanding the diameter of a wool pipe blank or a raw material pipe, a plurality of cold drawing processes are carried out. Accuracy and surface quality are obviously superior to those of hot-rolled steel pipe, but due to technological constraints, its diameter and length are limited to some extent.

  • Hot Rolled Seamless Steel Pipe

    Hot Rolled Seamless Steel Pipe

    Hot rolled seamless steel pipe: hot rolling is relative to cold rolling, which is carried out below recrystallization temperature, while hot rolling is carried out above recrystallization temperature.

    Q345B ERW Round Steel Pipe For Ecuador

    ERW Pipe stands for Electric Resistance Welded Pipe, featuring cost efficiency and a closer tolerance of wall thickness when compared with seamless steel pipe. It is widely used in fencing, scaffolding, engineering, etc. To ensure high precisions and quality of ERW Pipe, our SMC uses of high qualified materials, and have rigid quality control.

  • BS 1387 Hot Dipped Galvanized Steel Round Pipe

    BS 1387 Hot Dipped Galvanized Steel Round Pipe

    Hot dip galvanized round pipe is to make molten metal react with iron matrix to produce alloy layer, so as to combine the matrix and coating. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove iron oxide on the surface of the steel pipe, after pickling, the steel pipe is cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot-dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions take place between the substrate of hot-dip galvanized steel pipe and molten plating solution, forming a corrosion-resistant zinc-iron alloy layer with compact structure. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, it has strong corrosion resistance

  • SSAW Spiral Welded x42 Steel Pipe

    SSAW Spiral Welded x42 Steel Pipe

    Spiral welded pipe is made by rolling the steel strip of low carbon structural steel or low alloy structural steel into a pipe blank according to a certain helix angle (called forming angle), and then welding the pipe joints. It can produce large diameter steel pipes from narrow steel strips.
