Hot-rolled seamless steel pipe
Hot rolled seamless steel pipe, to be exact, is an important production process for seamless pipe. Its advantages can destroy the casting structure of steel ingot, refine the grain of steel, and eliminate the defects of microstructure, so as to make the steel structure compact and improve its mechanical properties. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent; Bubbles, cracks and porosity formed during pouring can also be welded under high temperature and pressure.
