Hot Dipped Galvanized / Pre Galvanized Square And Rectangular Hollow Section Steel Pipe And Tube 2191634116

Product Description

Hot dip galvanized Steel Pipe is to make molten metal and iron matrix reaction and produce alloy layer, so that the matrix and the coating of the combination of the two. Hot dip galvanized steel pipe is first pickling steel pipe, 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. Connection mode: threaded, welded.

Hot dip galvanized steel pipe has the advantages of strong corrosion resistance, not easy to rust, long life, relatively cheap price, etc..Hot dip galvanized steel pipe is more widely used in greenhouse.

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.
