Galvanized steel pipe refers to a welded steel pipe with a hot dip plating or electric galvanized layer on the surface, which is a special treatment to enhance the corrosion resistance of the steel pipe. The galvanized layer can effectively increase the corrosion resistance of the steel pipe, thus extending the service life of the steel pipe. Galvanized steel pipe is widely used in construction, medical, aviation, machinery, shipbuilding, light industry, agriculture and other industries.
Galvanized steel pipe is divided into cold galvanized steel pipe and hot galvanized steel pipe two kinds. Cold galvanized steel pipes have been banned, and hot galvanized steel pipes are heated and molten zinc liquid covered on the surface of the steel pipe to form a coating, and then cooled and solidified. The galvanized steel pipe has the characteristics of thick galvanized layer, smooth surface, strong adhesion, good corrosion resistance and long service life.
The manufacturing process of galvanized steel pipe includes the following steps: First, the steel pipe is pickled to remove the oxide film on the surface; Then hot dip galvanizing or electrogalvanizing; Finally, it is cooled and solidified. After these steps, the galvanized steel pipe is manufactured.
Galvanized steel pipe has a wide range of applications. In the construction field, galvanized steel pipe can be used for building water supply, drainage, heating and other pipeline systems. In the medical field, galvanized steel pipes can be used for the production and processing of medical devices. In the field of aviation, galvanized steel pipes can be used in the manufacture of aircraft, rockets and other aircraft. In the field of mechanical manufacturing, galvanized steel pipes can be used for the manufacture and processing of mechanical parts. In the field of shipbuilding, galvanized steel pipes can be used for the construction and maintenance of ships. In the field of light industry, galvanized steel pipes can be used for the production and processing of light industrial products. In the agricultural sector, galvanized steel pipes can be used for the construction and maintenance of irrigation systems.
In short, galvanized steel pipe is a steel pipe that has been specially treated to enhance its corrosion resistance and is widely used in various fields.
