Q345 Galvanized steel pipe
Products
Galvanized steel pipe is a kind of steel pipe with galvanized surface, which has good corrosion resistance and long service life. The galvanized layer can effectively protect the steel pipe from the corrosion of environmental factors such as atmosphere, water and soil, and reduce the rust and corrosion problems of the steel pipe, so as to extend its service life.
The manufacturing process of galvanized steel pipe mainly includes hot-dip galvanizing and electro-galvanizing in two ways. Hot-dip galvanizing is to immerse the steel pipe in molten zinc solution to form a dense zinc layer on the surface of the steel pipe, while electro-galvanizing is to deposit a layer of zinc on the surface of the steel pipe by electrolysis.
The characteristics of galvanized steel pipe are as follows:
Strong corrosion resistance: due to the galvanized surface, it can effectively prevent rust and corrosion of steel pipe and improve service life.
Convenient connection: it can be connected by welding, threaded connection and other ways, which is convenient for construction.
Wide range of application: It is widely used in construction, transportation, chemical industry and other fields, for example, it can be used to manufacture brackets, shells, pipelines and so on.
Relatively low price: compared with other materials of pipelines, the price of galvanized steel pipe is relatively low, which is suitable for mass production and application.
It should be noted that when using galvanized steel pipe, contact with acid, alkali and other chemicals should be avoided to avoid damage to the zinc layer. Meanwhile, excessive bending and twisting of the pipe should be avoided during installation and use to avoid damage to the pipe or affecting its service life.
