What Is the Difference between Galvanized Steel Pipe And Galvanized Seamless Steel Pipe?

Oct. 31, 2019

Galvanized seamless pipes are generally hot dip galvanized and have a thick galvanized layer for greater corrosion resistance and longer service life. With the improvement of construction quality, the service life and strength requirements of the pipeline system are also increased. Galvanized seamless pipe is often used instead of galvanized steel pipe for fire fighting, air conditioning and other pipeline systems for circulating water and gas medium transmission with higher requirements.

Compared with galvanized seamless steel pipes, galvanized steel pipes are more simple.


Hot dip galvanization is the pickling of welded steel pipe first, in order to remove iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning,and then it is sent into the hot-dip galvanizing tank.

The hot-dip galvanized steel pipe matrix and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant and compact zinc-iron alloy layer, and the alloy layer is integrated with the pure zinc layer and the steel pipe matrix.Galvanized seamless steel pipe is more corrosion-resistant and expensive than galvanized steel pipe.
