What is Hot Dipped Galcanized Pipe


The hot dipped galvanized pipe is used to make the molten metal react with the iron matrix to produce the alloy layer, so that the matrix and the coating are combined. The hot dipped 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 or ammonium chloride and zinc chloride mixed aqueous solution tank cleaning, and then sent to the hot dip plating tank. Hot galvanizing has the advantages of uniform coating, strong adhesion and long service life.Complex physical and chemical reactions occur between the steel tube substrate and the molten bath, forming a tightly corrosion resistant zinc-ferroalloy layer.The alloy layer is integrated with pure zinc layer and steel tube substrate.Therefore, it has strong corrosion resistance.

Hot Dip Galvanized Pipe Process


Hot dip galvanized pipe has the following production steps:

Black piece of check - hanging - skim - rinse - acid - cleaning - dipping plating aid to hot air drying, hot dip galvanized to cooling, passivation and rinse to unloading, inspection, trimming and packaging warehousing and transportation.

Products Feature

Our Customers prefer our Hot dipped Galvanized Steel Pipe because of the following reasons:

  • Smooth surfaces: Our galvanized steel pipe distributor ensure that the finished products are produced through a process that continuously ensures for smooth-surface, uniform wall pipe for superior and easy coatability and flow characteristics thereby ensuring the fluids are well transported through the pipes.

  • Stronger, lighter walls: Galvanized Steel pipe higher strength, lighter gauge steel strip is fused by high frequency electric resistance welders into high tensile steel pipe that meets tolerances and strength  of a high quality carbon galvanized steel pipe specifications.

  • Weight of galvanized layer: according to requirements of the buyer, the weight of galvanized steel pipe can be measured as zinc layer, and its average value should not be less than 500g/ m2
