Hot Rolled Seamless Steel Pipes

Hot Rolled Seamless Steel PipeMainly made of steel ingot,Website:http://www.alllandsteelpipes.com, the hot rolled seamless steel pipe is manufactured by treating the raw material with such processes as piercing, hot rolling, and size reduction. Different from cold rolling which is performed below the recrystallization temperature, hot rolling is conducted above the temperature. Hot rolled pipes offer higher torsional rigidity than cold rolled ones, thus they offer better torsional resistance than cold rolled tubes. By means of advanced technology, we produce 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, 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. The hot rolled seamless steel pipe is regularly used to construct the piping system for low, medium and high pressure boilers. Production ProcessRound tube blank → heating → piercing → three roller skew rolling, continuous rolling, or extruding → semi-finished tube → sizing or size reduction → cooling → straightening → water pressure test or flaw detection → marking → warehousing Technical Specifications Size Range: 4 inch~24 inch (114.3~609.6mm)Wall Thickness: 4.0~30.96mmStandard: API5L, ASTM A106Steel Grade: GR.A, GR.B, X42, X46, X52End Finish: Plain end, bevel end, thread, coupling, plastic capPipe Coating: Black vanish, bare, clear oil
