• Galvanized Coated Steel Tubing

    Galvanized Coated Steel Tubing

    Galvanized steel pipe is usually 6 meters in length, and the allowable weight per batch is no more than 5% of the total weight,Short length steel tube not less than 2 m。

  • Hot Dipped Galvanized Steel Pipe

    Hot Dipped Galvanized Steel Pipe

    Hot-dip Galvanized steel pipe is widely used in construction, automobile induatry, highway, brige, agricultureal machinery, and other manufacturing. Galvanized steel pipe with hot dip galvanized layer of welded steel pipe surface can increase the corrosion resistance of steel pipe and prolong its service life. Hot dip galvanized (galvanizing) is an effective way of metal corrosion is after rust removal of steel into the liquid zinc melting around 500 ℃, the zinc layer adhered on the surface of the steel members, which have the purpose of corrosion protection。

  • Galvanized BS1139 Pipes For Scaffolding

    Galvanized BS1139 Pipes For Scaffolding

    BS1139 galvanzied scaffolding steep is It is the longest and most widely used standard in the world. S235G straight seam welded steel tube with outer diameter of 48.3mm and wall thickness of 4.0mm shall be used for internal and external hot dip galvanization. According BS EN ISO the content of element carbon, SI, P, S, N was analyzed. The testing indexes of physical and mechanical properties of steel tubes are: tensile strength, yield and elongation. Colleague, BS1139 has clear requirements on product identification and packaging logistics. The use of scaffold steel tubes of BS1139 standard is an option that can effectively reduce the probability of scaffold accidents caused by material quality problems

  • BS1387 Water Pipes For Liquid

    BS1387 Water Pipes For Liquid

    BS1387 Galvanized steel pipes: 1. light weight, high strength, non-combustible, anti-aging, anti-corrosion, small resistance, good sealing performance, beautiful appearance, simple installation, long service life; 2 acid, alkali, salt and other corrosion resistance, can adapt to different regional climatic conditions, especially in coastal areas with high salt content in the air chemical fiber and other industries with or with volatile media, can reflect the advantages of its corrosion resistance.

  • Galvanized Steel Tube Manufacturers

    Galvanized Steel Tube Manufacturers

    Hot dip galvanizing (steel pipe) production process: Loading pickling, washing solvent drying hot galvanizing inner and outer blowing rolling mark, marking passivation inspection packaging. The feeder shall check the status of raw materials: 1. The external surface of the steel tube shall not be greasy, otherwise a large number of unqualified products will be produced. 2, the steel pipe must be straightened after production. 3, steel pipe surface uneven corrosion can not be galvanized, otherwise it will waste a lot of hydrochloric acid. 4, For hot-dip galvanized steel pipe, it is not allowed to stick the mark on the inner and outer wall of the steel pipe to avoid causing leakage plating.

  • Galvanized Carbon Steel Pipe Manufacturers

    Galvanized Carbon Steel Pipe Manufacturers

    The welded method of galvanized carbon steel pipes: ERW The process of using electric current to pass through the contact surface of the welded joint and the resistance thermal energy generated in the adjacent area to heat the welded metal to local melting or to reach the high temperature plastic state and form a solid welded joint under the action of external force is called ERW. The form of welding joints for resistance welding is limited to a certain extent, but the components suitable for resistance welding are still very extensive, for example, aircraft fuselage, car body and etc.

  • Galvanized Steel Pipes 48.3mm Dia

    Galvanized Steel Pipes 48.3mm Dia

    Galvanized steel pipes have nice performance in anti-corrosion. Gi pipe can be divided into hot galvanized and pre galvanized mainly. Hot galvanized pipe is thick in galvanization layer, so it behaves much well in corrosion resistant. While pre galvanized pipe is much economical. Surface quality 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.
