Generally greater than the hot-rolled seamless pipe diameter 32mm, wall thickness 2.5-75mm, rolled seamless steel pipe outside diameter to 6mm wall thickness can be 0.25mm, outer diameter thin-walled tube to 5mm wall thickness less than 0.25mm , cold than hot-rolled dimensional accuracy. Diameter more than 57mm in the pipeline project, often used in hot-rolled tube, diameter less than 57mm when used cold drawn (rolled) pipe.

General seamless steel pipe to ensure the strength and flattening test. Hot-rolled steel, hot-rolled state or heat treatment delivery; cold rolling to heat treatment delivery. Hot, as the name implies, the rolling temperature deformation resistance of the small and large deformation. Steel plate rolling, for example, general billet thickness of about 230mm, rough rolling and finish rolling, the final thickness of 1 ~ 20mm. At the same time, due to the steel plate width to thickness ratio is small, the dimensional accuracy requirements are relatively low, not prone to the flatness problem, mainly to control the crown. Requirements for the organization, usually by controlled rolling and cooling to achieve, that is, finishing the rolling temperature, finish rolling temperature and coiling temperature to control the microstructure and mechanical properties of the strip.
