Product Description

 

 Product Description

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, petroleum cracking pipes, and other steel pipes, as well as carbon thin-wall steel pipes, alloy thin-wall steel pipes, Stainless thin-walled steel pipes, special-shaped steel pipes. The outer diameter of hot rolled seamless steel tube is generally greater than 32mm and the wall thickness is 2.5-75mm. The diameter of cold rolled seamless pipe can be up to 6mm and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipe can be up to 5mm and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.
