Galvanized pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the 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 in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the in the hot dip bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Welded steel pipe, also known as welded pipe, is made of steel plate  or strip steel after crimping. The production process of welded steel pipe is simple, the production efficiency is higher, the cost is more lower, the product variety is getting richer, but the general strength is lower than seamless steel pipe.

Seamless steel pipe is a kind of long steel with hollow section and no seams around it. It is a kind of economic section steel,seamless steel pipe according to the different cross sectional area shape can be divided into round pipe and special-shaped pipe. Using seamless steel pipe to manufacture ring parts can improve the material utilization rate, simplify the manufacturing process, and save the material and processing time. Widely used in manufacturing structural parts and mechanical parts etc.
