  • Hot Dipped Galvanized Pipe In China

    Hot Dipped Galvanized Pipe In China

    Hot-dipped galvanized: In order to improve the corrosion resistance of steel pipe, the general steel pipe was galvanized. Galvanized steel pipe is divided into hot galvanized and electric galvanized two, hot galvanized galvanized layer thick, So it's very corrosion resistant. Surface quality: the surface of galvanized steel pipe should have a complete galvanized layer, there should be no unplated black spot, there is not much rough surface and the existence.

    Galvanized Pipe Factory In China

    Hot-Dipped Galvanized Surface Treatment: Galvanized steel pipe is the reprocessing of welded steel pipe, the welded steel pipe through hot plating process hot plating zinc to produce galvanized steel pipe. In order to improve the corrosion resistance of steel pipe, the general steel pipe was galvanized. It also has a wide range of USES, such as industrial process pipes,Small metal structure, electrical protection tube and other low-pressure fluid, and as a construction materials of building.

  • Galvanized Steel Tubing And Piping

    Galvanized Steel Tubing And Piping

    Basic principle of hot galvanizing process: Hot dip galvanized pipe is made of molten metal and iron matrix reaction and produce alloy layer, so that the matrix and coating of both. The alloy layer is integrated with the pure zinc layer and the steel tube matrix.Therefore, its corrosion resistance is strong.Galvanized steel pipe is divided into hot galvanized steel and electric steel zinc,Thick hot dip galvanized coating, Low cost of galvanizing.

  • China Galvanized Steel Water Pipes

    China Galvanized Steel Water Pipes

    The process of Hot-dipped Galvanized : Hot dip galvanized pipe is made of molten metal and iron matrix reaction and produce alloy layer, so that the matrix and coating of both.Hot dip galvanizing is to pickling the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, and then into the hot dip plating bath.Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

  • Threaded Galvanized Tubes With Couplers

    Threaded Galvanized Tubes With Couplers

    Galvanized pipe with thread at both ends is a kind of pipe fitting widely used at present, which has many processing methods. 1) Forging and pressing method: the end or part of the pipe shall be punched and stretched with the die forging machine, so that the outer diameter of galvanized pipe at both ends can be reduced. 2) Stamping method: the tube end is expanded to the required size and shape on a punch with a tapered core. 3) Rolling method: generally do not use mandrel, both ends of the wire galvanized pipe suitable for thick wall tube inside the round edge.

  • Schedule 40 Galvanized Steel Pipes

    Schedule 40 Galvanized Steel Pipes

    Schedule 40 Mean : There are three methods to express the wall thickness of steel tube: pipe number, pipe wall thickness and pipe weight, Inch wall thickness series Sch40 full name: Schedule 40. Hot-dipped Galvanized Treatment technological process: Workpiece degreasing washing pickling washing immersion plating solvent drying preheating hot galvanizing finishing cooling passivation rinsing drying inspection

  • Welding Hot Dipped Galvanized Pipes

    Welding Hot Dipped Galvanized Pipes

    Pre-Galvanized steel: Weight: 6 meters long with 5.5 kg (corrosion resistance is slightly poor, service life is shorter than that of hot-dip galvanized steel pipe, the price is low economy).Zinc-coated tube is shiny white and reflective, rarely snowflake shape. Hot-dipped galvanized steel pipe: Weight: 6 meters long with 6.5 kilograms (strong corrosion resistance, long service life, slightly higher price); Complex physical and chemical reactions take place between hot galvanized steel tube substrate 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 tube matrix.Therefore, its corrosion resistance is strong.
