You are currently：home > products > hot rolled steel pipe hot rolled steel pipe we produce technology advanced hot rolled seamless steel pipes using continuous tube rolling mills. Our products offer various outstanding features and comparative advantages, manifested by the way we manufacture the hot rolled steel pipe. During the manufacturing process, the raw material's cast structure is destroyed, and the steel material's crystalline grain is refined, and the microscopic structure's defects are eliminated. This contributes to densified steel product microstructure, and improved mechanical property. Therefore, hot rolled seamless tubes are not an isotropic body anymore, and the air bubble, cracks, and porosity can be completely eliminated at the high temperature and pressure processing condition.
