Seamless pipes are made of steel ingots or solid pipe blanks through perforation into capillary pipes, which are then hot-rolled, cold-rolled or cold-drawn. It occupies an important position in my country's steel pipe industry. So what should be paid attention to when producing seamless pipes?

Nowadays, the surface of the welded tubes we use are required to be coated for corrosion protection. So do you know how the welded tube is anti-corrosion?

Seamless pipe refers to a steel ingot or solid pipe blank that is perforated into a capillary pipe, and then hot-rolled, cold-rolled or cold-drawn. As a kind of economic section steel, what are the characteristics of seamless pipe in its production process?

Cold drawn seamless pipes refer to steel pipes with high dimensional accuracy and good surface finish used in mechanical structures and hydraulic equipment. Heat treatment is an essential process in its production process, this is why?

According to the production process, U-shaped steel sheet piles are divided into two types: cold-formed steel sheet piles and hot-rolled steel sheet piles. In engineering construction, cold-formed steel sheet piles are relatively cost-effective, and in engineering applications, the two types can be substituted for each other. So how are U-shaped steel sheet piles generally constructed?

Cold drawn seamless pipe has the advantages of no oxide layer on the inner and outer walls, no leakage under high pressure, high precision, high finish, no deformation after cold bending, no cracks in flaring and flattening, and anti-rust treatment on the surface.
