ISO9001 Psl2 12m Galvanized Carbon Steel Pipe A106B

GB/T 3091 Welded Steel Pipe Anti Corrossion Galvanized Carbon Steel Pipe

Hot dip galvanized pipe is to make molten metal and iron matrix reaction to produce alloy layer, so that the substrate and coating are combined.Hot dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent into the hot dip plating tank.

Galvanized steel tubes are welded steel tubes with hot dip or electric galvanized coating on the surface.Galvanizing can increase the corrosion resistance of steel pipe and prolong its service life.Galvanized pipe USES is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube, etc.
