Steel pipe knowledge

Spiral welded pipe is a welded steel pipe produced by a continuous spiral forming process. It has the characteristics of light weight, high strength, corrosion resistance and long service life.

Spiral steel pipe, as an important building material, is widely used in construction, chemical, petroleum, natural gas and other industries.

There are two types of galvanized steel pipe: hot-dip galvanized pipes and cold-dip galvanized pipes. Relatively speaking, hot-dip galvanized pipe are less prone to rust than cold-dip galvanized pipe.

There are various methods to improve the surface quality of seamless steel pipe, and appropriate measures should be selected according to the situation to enhance the surface quality of seamless pipe.

GI galvanized pipe is widely used in many fields such as construction, water conservancy, electricity, and transportation due to its excellent corrosion resistance and long service life.

Structural pipes and fluid pipes are two major types of steel pipe applications. In practical project applications, we need to know the differences between them, can they be universal?

In various industries, the demand for sturdy and versatile structural components is critical. One such component that has gained widespread usage is the 2 x 5 rectangular tube.

For steel pipe buyers, galvanized square steel pipe is one of the common pipes.

EN10219 and EN10210 certifications are two important certification standards for European steel pipe products, which ensure that the products produced have advantages in multiple aspects.

The utility model relates to the field of metal material processing technology, and further relates to a square rectangular steel pipe formed by corner thickening and cold hot composite forming.

To prevent decarburization of rectangular tube products, the most effective measure currently adopted is to add alloy elements. Generally, adding Sb and Sn to suppress quenching decarburization.
