Galvanized Steel Pipes
Galvanized Seamless Steel PipeGalvanized seamless pipe is divided into cold-plated seamless pipe and hot dip seamless pipe.Cold-plated galvanized seamless pipeCold electro-galvanized pipes are resistant to corrosion,Website:, but the zinc thickness is only 10-50g/m2, far less than that of hot dip galvanized pipe. But the price of electro-galvanized (cold-plated) seamless steel pipes is cheap.Hot dip galvanized seamless pipeHot dip galvanizing is to make the molten zinc and iron substrate react physically so that the zinc coating adheres to the substrate permanently. Before being treated by hot zinc liquid, the pipes are treated by de-rusting. Hot dip galvanized coating is strong in adhesion and long in service life.
