Seamless steel pipe specifications usually outside diameter * thickness (unit: mm), said. Seamless steel pipe production methods can be divided into hot-rolled seamless steel tubes and cold-rolled (allocated) seamless steel pipe two categories. Hot-rolled seamless steel pipe is divided into general steel pipes, low and medium pressure boiler pipe, high-pressure boiler steel pipes, alloy steel pipe, stainless steel, petroleum cracking tubes, geological steel pipe and other pipe and so on. Rolled (allocated) seamless steel Subject to sub-general steel pipe, low and medium pressure boiler pipe, high-pressure boiler steel pipe, steel pipe, stainless steel pipe, petroleum cracking tubes, other steel pipes, including precision steel tubes, carbon steel tubes, alloy thin wall steel pipe, stainless steel tubes and shaped steel tubes.

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.
