Knowledge of galvanized steel pipe

Galvanized steel pipes are divided into hot-dip galvanized steel pipes, cold-galvanized steel pipes, and galvanized strip steel pipes, commonly known as white steel pipes. A protective layer is formed on the outer surface of the galvanized steel pipe, and a zinc alloy layer is formed under the protective layer. The zinc alloy layer can prevent iron from being oxidized at high temperatures and prevent rust from corroding steel. Therefore, galvanizing has become an important method to prevent steel oxidation and rust corrosion under the protective layer, and it is also a commonly used anti-corrosion method for steel. Galvanized steel pipes are used in a wide range of applications, such as mining equipment, construction industry, automobile industry and shipbuilding industry. The galvanized layer of galvanized steel pipes mainly uses zinc-based compounds for chemical galvanizing in my country, so that a stable zinc film is formed on the surface of the steel parts to achieve anti-corrosion effects.

For many industries, galvanized steel is one of the very important raw materials, it is one of the important materials in coal mining, transportation vehicles, petrochemical, infrastructure and other industries. The surface of galvanized steel pipe is specially treated, which can effectively improve the corrosion resistance and service life of steel parts, so it has high market value and broad application prospects.

The galvanized spiral steel pipe made of spiral pipe is called galvanized spiral steel pipe. The common steel pipe dimension is 219-3820mm. The seamless steel pipe that has been galvanized is called galvanized seamless steel pipe, and the model size is 10-1020mm. The galvanized welded steel pipe made of welded steel pipe is called galvanized welded steel pipe, and the model size is 21-1220mm. There are also steel pipes formed by mechanical processing of galvanized strips called galvanized strip steel pipes. Due to the high cost of galvanized seamless steel pipes, the price is higher than that of galvanized welded pipes. Pay attention to identification when purchasing.
