What is hot rolled seamless steel pipe?
Hot-rolled seamless steel tube, in fact, is relative to cold-rolled seamless steel tube, mainly refers to seamless steel tube rolled above recrystallization temperature. Hot rolled seamless steel tubes are mainly divided into ordinary seamless steel tubes, high, medium and low pressure boiler steel tubes, alloy steel tubes and stainless steel tubes.
What are the advantages of hot rolled seamless steel pipe?
The biggest advantage of hot-rolled seamless steel tube is that it destroys the casting structure of ingot as raw material, thus refining the internal grains of steel, eliminating the defects of steel microstructure, making the internal structure of steel more dense, and finally improving the internal mechanical properties of steel.
What are the disadvantages of hot rolled seamless steel pipes?
First of all, if there are nonmetallic impurities in the hot-rolled seamless steel tube, the hot-rolled seamless steel tube is prone to peeling and delamination, which will tear the weld of the seamless steel tube. Secondly, if the hot-rolled seamless steel tube is cooled unevenly during the cooling process, it is easy to produce residual stress in the seamless steel tube, which will adversely affect its deformation performance, stability performance and fatigue resistance during use. Finally, it is not easy to control the thickness, sideline and angle of hot rolled seamless steel pipe products.
