Short Description:

Galvanized square pipe  is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, the latter is also advocated by the state can be used temporarily. In the 1960s and 1970s, the developed countries in the world began to develop new types of pipes and gradually banned galvanized pipes. China’s Ministry of Construction and other four ministries and commissions have also issued a document to prohibit galvanized pipes as water supply pipes from 2000, the cold water pipes in the new community have rarely used galvanized pipes, and the hot water pipes in some communities use galvanized pipes. Hot-dip galvanized steel pipe has a wide range of applications in fire, power and highway.

    Product Detail

    Galvanized square pipe is a kind of hollow square cross section steel pipe with square section shape and size made of hot rolled or cold rolled galvanized strip steel or galvanized coil as blank through cold bending processing and then through high frequency welding, or the cold formed hollow steel pipe made in advance and then through hot dip galvanized square pipe

    Main Application

    Features

    Hot dip galvanized pipe is the reaction of molten metal with iron matrix to produce alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the steel pipe, in order to remove the iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The matrix of hot dip galvanized steel pipe and the molten bath undergo complex physical and chemical reactions to form a tight zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix, so its corrosion resistance is strong.

    Application

    Application

    Hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highways, Bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
    Galvanized steel pipe is a welded steel pipe with a hot dip plating or electric galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and extend the service life. Galvanized pipe has a wide range of uses, in addition to the pipeline pipe for water, gas, oil and other general low pressure fluids, it is also used as the oil well pipe, oil pipeline, especially in the oil field of the petroleum industry, the oil heater, the condensing cooler of the chemical coking equipment, the tube for the coal distillation and washing oil exchanger, and the pipe for the trestle pipe pile and the support frame of the mine tunnel.
