51 Steel pipe network provides: What is the use of hot-rolled seamless steel pipe? Tube blanks are directly used in steel ingots. When the continuous casting technology is not mature, all are used. That is to say, steel ingots are rolled into billets on a blooming mill. Then, the steel bar is called a round billet. When the continuous casting technology matures, the continuous casting billet is directly used as a billet. The continuous casting method used in continuous casting blanks is divided into horizontal continuous casting blanks and curved continuous casting blanks. As for the hollow billet, it is not currently used in industrial production.
The billet forming methods used for hot rolled seamless steel tubes can be classified into steel ingots, rolling billets, coupling blanks, billets and casting hollow billets. According to whether the tube blank is to be perforated, it can be divided into a solid blank and a hollow blank. According to the use of steel pipes can be divided into: low and medium pressure boiler tube blanks, high pressure boiler tube blanks, high pressure chemical fertilizer equipment tube blanks, structural tube blanks, conveying fluid tube blanks, petrochemical tubes Tube blanks, tube supports for hydraulic support brackets, tube blanks for gas cylinders, tube blanks for line tubes, and tube blanks for oil drilling.
Nano is an innovative technology that can deposit very fine and thin metal films on products. Applied to stainless steel sinks, this technology ensures the durability and longevity of the product's color and helps maintain its beauty. Nano-coating makes the sink antibacterial, waterproof and oil resistant.
