HDG Pipe

HDG pipe, which is also called Hot Dip Galvanized Pipe or Galvanised Metal Pipe.

 

Hot-dip galvanizing (HDG) is the reaction of a molten metal with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating. 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 washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot dip galvanized steel pipe has the advantages of uniform plating, strong adhesion and long service life.

 

Galvanizing is a technology of rust protection. The steel and zinc are will interact and become Zn-Fe alloy on the pipe surface. The layer of alloy can provide protection from outside oxidation and extend the pipe use life. The service life of a galvanized steel pipe can be 20-30 years in the outdoor environment.

Industrial hot-dip galvanized steel pipes are widely used in construction, machinery, coal, chemical, electric power, railway vehicles, automotive industry, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery manufacturing industry.

 

Welded galvanized steel pipe with hot-dip or electric galvanized layer on the surface. Galvanized steel can increase the corrosion resistance of the steel pipes and prolong the service life. Galvanized pipe USES is very wide, in addition to a generally low-pressure fluid such as water, gas, oil line pipe, also used as the oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for the tube, and trestle pile, mining tunnel supporting frame tube, etc.
