HDG Galvanized Steel Pipe For Sale

Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.

The dense zinc-iron alloy layer of the hot-dip galvanized steel pipe is integrated with the pure zinc layer and the steel tube base, which has strong corrosion resistance.

As long as the forming angle is changed, hot dip galvanized steel tubes of various calibres can be produced from strip steel of the same width.

Continuous bending and forming, the fixed length of the spiral tube is not limited, and the length can be customized.

The spiral welds are evenly distributed on the circumference of the spiral pipe, so the spiral pipe has high dimensional accuracy and strong strength.

It is suitable for the production of small batches and multiple varieties of spiral tubes. The welding seam of hot dip galvanized pipe is longer than the welding seam of the straight seam pipe of the same specification. With the same wall thickness, the hot dip galvanized pipe bears the greatest pressure. There is the A795 pipe, DN15-200 pipe, EN39 pipe, A500 steel pipe, etc. in this category.

HDG steel pipe, which is also called Hot Dip Galvanized Pipe or Galvanised Metal Pipe. Tianchuang is one of the most famous hot-dip galvanized pipe manufacturers in China. If you want to know the hot-dip galvanized steel pipe price, please contact us as soon as possible!

3. Application of Hot Dip Galvanized Steel Pipe

Like erw steel pipes, 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.


4.Advantages of Hot Dip Galvanized Steel Tube

Hot-dip galvanizing (HDG) is the reaction of 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 galvanizing 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.


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 steel 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.


Hot-dip galvanized pipe manufacturers always provide good quality galvanized steel pipe for sale according to customers' needs, and Tianchuang can be the best of them. Contact us to know the hot-dip galvanized pipe specification and get the price for galvanized steel pipe.


FAQ of Hot Dip Galvanized Pipe

Is hot-dipped galvanized the same as galvanized?

Hot dipped galvanizing is a type of galvanizing. The major difference between galvanized and hot dipped galvanized strands at the characteristics of the material. Galvanized materials have a smooth and sharp finishing while hot sip galvanized structure is designed with a feature of rough finishing. In addition, the process of galvanizing covers the form achievement of a layer of zinc to prevent the metal from corrosion. Whereas hot dip galvanization is the formation of a pure zinc layer on the surface of the metal by surface preparation, galvanizing and inspection.


How long of hot galvanized steel pipe lifetime?

Hot dip galvanized steel pipes have a long lifetime. But under uncertain circumstances, the lifetime of hot dip galvanized steel pipes varies from one to another based on their applications or uses. In general, 13 years in the heavy industrial district, 50 years for the ocean environment, 104 years in suburbs, 30 years in the city are possible. As a matter of fact, hot dip galvanized steel pipes play an important role in anti- rusty.  Hot dip galvanized steel tube process especially suitable for kinds of strong-acid, alkali fog and other strong corrosive conditions. These types of fasteners are used widely outside of steel tower contribution.
