Advantages of hot rolled seamless tube

Hot-rolled seamless steel tubes are divided into general steel tubes, low- and medium-pressure boiler steel tubes, high-pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological steel tubes, and other steel tubes. Advantages of hot-rolled seamless steel tube: It can destroy the cast structure of steel ingot, refine the grain of steel, and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic; to a certain extent, the bubbles, cracks and looseness formed during casting can also be welded under high temperature and pressure.
