Because it is hot rolled, so cost is lowest, but it is suit for large quantity, for small quantity, have to make cold drawn or round bar piercing. size:outer diameter 32mm- 499mm , wall thickness 4mm- 80mm

Cold Rolled Seamless Steel Tube

Cold rolled seamless steel tubes are cold-drawn or cold-rolled precision seamless steel tubes used for mechanical structures and hydraulic equipment with high dimensional accuracy and good surface finish. Cold rolled seamless steel tubes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes Differences between Hot Rolled and Cold Rolled Seamless Aug 19, 2020 · Cold-rolled seamless tubes are rolled below the recrystallization temperature, while hot-rolled seamless tubes are rolled above the recrystallization temperature. Advantages:It can destroy the casting structure of the steel ingot, refine the grain of the steel, and eliminate the defects of the microstructure, so that the steel structure is dense and the mechanical properties are improved. How to choose boiler tubes - China Pipe Fittings, Steel Nov 14, 2018 · The general boiler tube use temperature is below 350 °C, and the domestic tube is mainly made of 10 or 20 carbon steel hot rolled tube or cold drawn tube. High pressure boiler tubes are often used in high temperature and high pressure conditions, and the tubes are used in high temperature flue gas and water vapor.

How to distinguish hot rolling and cold rolling seamless tube?

Cold rolled seamless pipe in addition to include the general steel, low and medium pressure boiler tube, high-pressure boiler tubes, alloy steel pipe, stainless steel pipe and oil cracking tube, also includes carbon thin wall steel pipe, alloy thin wall steel tube, thin-walled stainless steel pipe and special-shaped steel tube. The diameter of cold rolled seamless steel pipe is 6mm, wall thickness is 0.25mm, while the diameter of thin-walled tube Rapid SteelHot & Cold Rolled Steel.
