China Wholesale Galvanized Square Steel Pipe Suppliers - High Quality Galvanized Steel Pipe – Xinsuju
Product Details Hot dip galvanized steel pipe is to make molten metal react with iron matrix to produce alloy layer, so as to combine the matrix and coating. Hot dip galvanizing is to pickle the steel pipe first. In order to remove iron oxide on the surface of the steel pipe, after pickling, it is cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip galvanizing tank. Hot dip galvani... -

China Wholesale Steel I-Beam Sizes Suppliers - High Quality Galvanized Square Pipe – Xinsuju
Hot dip galvanized square pipe Hot dip galvanized square pipe: it is a square pipe welded after crimping and forming with steel plate or steel strip, and on the basis of this square pipe, the square pipe is placed in the hot-dip galvanized pool and formed after a series of chemical reactions. Galvanized square pipe is divided into hot-dip galvanized square pipe and cold galvanized square pipe from the production process. It is precisely because of the different processing of the two galv... -
China Wholesale Seamless Steel Pipe Factories - High Quality Seamless Steel Pipe – Xinsuju
Production Process The general production process of seamless steel pipe can be divided into cold drawing and hot rolling. The production process of cold-rolled seamless steel pipe is generally more complex than hot rolling. The pipe blank must first be subject to three roll continuous rolling, and the sizing test shall be carried out after extrusion. If the surface does not respond to the crack, the round pipe must be cut by a cutter to cut the blank with a growth of about one meter. Th... -
