Galvanized ERW steel pipe
Hot dip galvanized steel pipe
Hot dip galvanized pipe is made of metal and molten iron alloy body reaction layer, so that it can combine the coating and the matrix.Is hot dip galvanized steel pipes to pickling, in order to remove iron oxide on the surface of the steel tube after acid cleaning, by ammonium chloride or zinc chloride solution or ammonium chloride and zinc chloride aqueous solution tank, and then into the hot dip tank.Hot dip galvanizing has a advantage of uniform coating, adhesion strong, long life etc..
Hot Dipped Galvanized Steel Pipes
Plating steel substrate and melting of the physical, chemical reaction to form complex structure, corrosion resistance of zinc alloy layer closely.Pure zinc alloy layer and layer and steel substrate.So the corrosion resistant ability.

Galvanized Steel Pipe can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements.Hot Dip Galvanized Steel Pipe Trading,Zinc Galvanized Round Steel Pipe For Building Material has been used used for water-supply pipes or as a strong tubing for outdoor applications.
Galvanized Steel Pipe is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. Hot Dip Galvanized Steel Pipe Trading,Zinc Galvanized Round Steel Pipe For Building Material is also sometimes called galvanized iron pipe. Galvanized steel pipe has been coated with a layer of zinc. The zinc provides a barrier against corrosion so that the pipe may be exposed to the outdoor environmental elements.Galvanized Steel Pipe The protective barrier proves equally effective against damage from indoor humidity.Hot Dip Galvanized Steel Pipe Trading,Zinc Galvanized Round Steel Pipe For Building Material is covered with a zinc material to make the steel pipe more resistant to corrosion.
