Q195 Q235 Q235B API 5L PSL1 X70M ERW Galvanized Steel Pipe

Galvanized steel pipes are covered by a layer of zinc, which are mostly used in structural applications and be available in various sizes and shapes based on the customers' requirements. The hot-dip galvanized steel pipe is formed with high quality welded tube and advanced galvanization technology and equipment, both inside and outside surface are smooth, without black spot or bleb. It features high corrosion resistance and is widely used as wire tubing under the poor condition.

Product Description

Hot-dip galvanizing is the reaction of the molten metal with the iron matrix to produce an alloy layer, so that both the substrate and the coating are combined. The hot-dip galvanizing pipe is made by pickling the steel pipe to remove the iron oxide on the surface of the steel pipe. After pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank , And then into the hot dip bath.

Hot-dip galvanized steel pipe is a steel pipe matrix and molten bath complex physical and chemical reactions, the formation of corrosion-resistant structure of the zinc-iron alloy layer. Alloy layer and pure zinc layer, steel pipe body integration, so hot-dip galvanized steel pipe with uniform coating, strong adhesion, long life and other advantages

ERW pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes. Our product finds its usage for Agricultural purposes, Drinking Water for housings, in collieries for extraction of Water, Thermal Powers, Transports, Hand pumps for deep boring wells, as a strong protection for cables by Telecom Department, Structural Purposes etc. While manufacturing ERW steel pipes, only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance
