China Wholesale Sch40 Welded Round Steel Pipe Tubes 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 Erw Welded Steel Pipe Suppliers - 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... -
