Differences between Hot Rolled and Cold Rolled Seamless

Aug 20, 2020 · Aug 20, 2020 · Cold drawn (rolled) tubes are divided into round tubes and special-shaped tubes. 1) Different uses Hot-rolled seamless pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other How to distinguish hot rolling and cold rolling seamless tube?Hot rolled seamless steel pipe is generally divided into low, medium, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, geological steel pipe and other steel pipe. The outside diameter of hot rolled seamless tube is generally greater than 32mm and the wall thickness of that is 2.5-75mm. Difference High-resistant tubes, boiler tubes, duplex tubes15CDV6 / 1.7734. 20MnV6 / 1.5217 / E470. Seamless alloy tubes for thermal improvement. Boiler tubes for high temperature operation. Tubes on furnace muffles and thermocouples guards. Steam pipes and superheater tubes. Stainless steel pipes, chromium-nickel corrosion-resistant.
