Galvanized steel pipe refers to a steel pipe coated with a layer of zinc on the surface of ordinary steel pipes. Galvanizing is an electrochemical process that forms a protective layer of zinc on the surface of a metal, mainly to prevent corrosion of the metal and increase its durability.

Galvanized steel pipe surface layer above the added galvanized layer, in this case, the steel will not appear corrosion and rust, and its own use time will increase. In addition, the zinc layer can form a protective film on the surface of the steel pipe, effectively extending the service life of the steel pipe and improving the corrosion resistance of the steel pipe. The characteristics of galvanized steel pipe mainly include the following aspects:

Good corrosion resistance. The zinc layer on the surface of galvanized steel pipe can play a good role in corrosion resistance and effectively prevent the steel pipe from being corroded by oxidation.
Resistant to weathering. The surface hardness of galvanized steel pipe is high, it has strong weathering resistance and can adapt to different use environments.
Good fire resistance. Galvanized steel pipe is a non-combustible material, which can effectively prevent the occurrence of fire accidents and ensure the safety of use.
Beautiful in shape. The surface of galvanized steel pipe is smooth and smooth, the color is beautiful, and it has a strong decorative effect.
The quality is stable. The production process of galvanized steel pipe is mature, the production process standard is high, and the quality is stable.

Material introduction

Galvanizing is an electrochemical process that forms a protective layer of zinc on the surface of a metal, mainly to prevent corrosion of the metal and increase its durability. This treatment technology is widely used in various metal parts, especially steel products, to provide long-term protection. The following details the galvanizing process, characteristics, types and application fields.

Galvanizing process
The galvanizing process usually consists of the following steps:

Pretreatment: Before starting galvanizing, the metal surface needs to be cleaned and pretreated to remove oil, rust and other impurities. This can be done by chemical cleaning, mechanical cleaning or sandblasting.
Zinc plating: The pre-treated metal parts are immersed in molten zinc, or by electroplating, a layer of zinc is formed on the metal surface. Molten galvanizing involves immersing metal parts in a molten zinc bath and combining zinc with a metal substrate through thermal diffusion. Electrogalvanizing is a process by which a layer of zinc is deposited on the surface of the metal.
Post-treatment: After galvanizing, post-treatment steps such as cooling, passivation or coating may be required to further improve the corrosion resistance and appearance quality of the galvanizing layer.
Characteristics of galvanizing
Excellent corrosion resistance: zinc is a lively metal, easy to react with oxygen in the air to form a dense zinc oxide protective film, this protective film can effectively prevent further oxidation and corrosion of the metal substrate.
Good electrical and thermal conductivity: Galvanized layer has good electrical and thermal conductivity properties, which can play an advantage in some specific application scenarios.
Easy processing and forming: The galvanized layer has less plastic influence on the metal substrate, so the galvanized metal parts are still easy to further processing and forming.
Beautiful and generous: the galvanized layer has a silver-white appearance, giving people a neat and beautiful feeling.
Types of galvanizing
According to the galvanizing method and the structure of the zinc layer, galvanizing is mainly divided into the following categories:

Hot dip galvanizing: This is the most common method of galvanizing and is achieved by dipping metal parts into a molten zinc bath. The zinc layer formed by hot dip galvanizing is thicker and has strong corrosion resistance.
Electrogalvanizing: Depositing a thin layer of zinc on a metal surface through an electrolysis process. The electrogalvanizing layer is relatively thin, but the appearance is smooth and smooth, which is suitable for some occasions with high aesthetic requirements.
Mechanical galvanizing: This is a relatively new method of galvanizing, which combines zinc powder with metal substrate by mechanical force to form a thin zinc layer. The mechanical galvanizing process is simple and environmentally friendly, but the corrosion resistance may be slightly inferior to that of hot dip galvanizing and electric galvanizing.
