ASTM Galvanized steel pipe

ASTM 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.

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.

Application:

It is a long piece of steel with a hollow cross-section and no seams around it. Steel pipe has a hollow cross-section and is used in large quantities as a pipeline for the transportation of fluids such as oil, natural gas, coal gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight when the bending and torsion strength is the same, and it is a kind of economic cross-section steel, which is widely used in the manufacture of structural and mechanical parts, such as oil drilling rods, automobile driveshafts, bicycle frames, and steel scaffolding used in building construction. Steel pipe manufacturing ring-shaped parts, can improve material utilization, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc., is widely used in steel pipe to manufacture. Steel pipe or a variety of conventional weapons indispensable materials, gun barrels, gun barrels, etc. to steel pipe to manufacture. Steel pipe according to the shape of the cross-sectional area of different can be divided into round pipe and shaped pipe. Since the circular area is the largest under the condition of equal perimeter, more fluid can be transported with circular pipe. In addition, the circular cross-section is more uniformly stressed when subjected to internal or external radial pressure, therefore, the vast majority of steel pipes are round pipes. However, the round tube also has certain limitations, such as under the conditions of plane bending, round tube is not as strong as the square, rectangular tube bending strength, some agricultural equipment skeleton, steel and wood furniture, etc. are commonly used square, rectangular tube. According to different uses also need to have other cross-sectional shape of the shaped steel pipe.
