Galvanized pipe refers to a product that forms a uniform and dense zinc layer on the surface of the steel pipe after galvanizing, thereby improving the corrosion resistance of the steel pipe.

Galvanized pipe refers to a product that forms a uniform and dense zinc layer on the surface of the steel pipe after galvanizing, thereby improving the corrosion resistance of the steel pipe. The galvanizing treatment is mainly achieved through hot-dip galvanizing or pre-galvanizing processes, so that the pipe can effectively resist the erosion of the atmosphere, water vapor and other corrosive media in various environments, thereby extending the service life.

 

 

Main production process:

 

Hot-dip galvanizing

 

After pretreatment such as cleaning, pickling and passivation, the steel pipe is directly immersed in a molten zinc bath to cause a metallurgical reaction between the zinc and the steel substrate to form a thick and firmly attached zinc layer.

 

The hot-dip galvanizing process is suitable for occasions requiring high corrosion resistance, and the product surface often has a unique zinc pattern.

 

Pre-galvanizing

 

The pre-galvanizing process is generally a continuous galvanizing process during the production of steel coils, and then processed into pipes.

 

The galvanized pipe produced by this process has a thinner coating and a smoother appearance, which is suitable for fields with certain requirements on appearance and cost.

Main uses

 

Galvanized pipes have a wide range of application scenarios due to their corrosion resistance, high strength, and easy processing:

 

Construction field: used in building exterior walls, roofs, rainwater drainage pipes and other occasions to ensure that the pipes are weather-resistant for a long time and not easy to rust.

 

Water supply and drainage system: In municipal engineering, industrial pipe networks and household water supply systems, galvanized pipes can effectively prevent water pollution and extend service life.

 

HVAC: In air conditioning and heating systems, galvanized pipes not only ensure heat transfer effects, but also avoid leakage problems caused by corrosion.

 

Power and communications: In the fields of cable protection and communication line laying, galvanized pipes are used as protective casings to prevent metal corrosion and external interference.
