Introduction of galvanized pipe of Shenzhen profile manufacturer

It is mainly used in curtain wall, construction, machinery manufacturing, shipbuilding, steel structure engineering, solar energy, electric bracket, steel structure engineering, electric power engineering, electric power, agriculture, chemical machinery, glass curtain wall, automobile chassis, airport and so on.
Introduction to galvanizing
Zinc plating has strong protection and strong corrosion resistance. The entire structure is formed by the crystallization of zinc, a quaternary crystal, which is an obstacle on the steel plate in the form of crystals, thus effectively preventing the penetration of corrosion factors. The zinc corrosion protection function from the barrier layer of the insurance is strong. When zinc is in the cutting edge, scratches and scratches are used as a sacrificial anode protective coating, the oxide layer forms insoluble zinc, and the black tube on the wall increases the weight coefficient mm mm mm ordinary steel thick steel 610.02 1.064 1.0598 13.5 2.75 1.056 1.04610 17 3.50 1.056 1.04615 21.3 3.15 1.047 1.03920 26.8 3.40 1.046 1.03925 33.5 4.25 1.039 1.03232 42.3 5.15 1.039 1.03240 48 4 1.036 1.03050 60 5 1.036 1.02865 75.5 5.25 1.034 1.02880 88.5 4.25 1.032 1.027100 114 7 1.032 1.026125 140 7.50 1.028 1.023150 165 7.50 1.028 1.023 Display W = C * [ 0.02466 × thick galvanized nominal diameter pipe (DS) × S ] Note W - galvanized steel pipe weight per meter: kg / m carbon pipe ratio - black pipe increases D weight system
(1) Galvanized pipe, the pure zinc layer is densely covered on the surface of the steel, which can avoid any corrosion solution contacting the steel substrate and protect the corrosion of the steel substrate. In the general atmosphere, a zinc layer is formed on the surface of a thin layer of dense zinc oxide layer, which is hardly soluble in water, so the protection of the steel matrix. If other components of zinc oxide and the atmosphere form insoluble zinc salts, then the anti-corrosion effect is more ideal.
(2) galvanized pipe, with iron-zinc alloy layer, dense, salt spray atmosphere at sea and industrial atmospheric corrosion resistance characteristics;
(3) Because the galvanized pipe is firmly bonded, the zinc-iron is miscible and wear resistant;
(4) Since the galvanized pipe has good ductility and firmly adheres to the alloy layer and the steel on the substrate, the hot plating can be cold-stamped, rolled, stretched, bent, and the like without damaging the coating;
(5) Galvanized pipe, hot-dip galvanizing, equivalent to annealing treatment, can effectively improve the mechanical properties of the steel matrix, eliminate the forming and welding stress of the steel, and is beneficial to the rotating behavior of the steel structure.
(6) The hot-dip galvanized surface is bright and beautiful in galvanized pipes.
(7) galvanized pipe, pure zinc layer is rich in plasticity of hot-dip galvanized galvanized layer, and pure zinc is basically close to nature's ductility, so it is flexible
