Description
GB/T8163 seamless steel pipe for liquid service
GB/T8163 Seamless steel pipe for fluid service is a kind of steel pipe with hollow section and no weld overall. It is generally used for conveying water, oil, natural gas, gas and other fluids.It is mainly used for engineering and large equipment to transport fluid pipelines. Because of its manufacturing process is different, it is divided into hot rolled (extruded) seamless steel tube and cold drawn (rolled) seamless steel tube two kinds. Because in the condition of the same perimeter, the area of the circle is the largest, the circular steel tube can transport more fluid, in addition to the circular section under the internal or external radial pressure of the force is more uniform, so the vast majority of fluid transport seamless steel tube is round.

Application
General boiler pipe is mainly used to manufacture water wall pipe, boiling water pipe, superheated steam pipe, locomotive boiler superheated steam pipe, large, small smoke pipe and arch brick pipe.
High pressure boiler tube is mainly used to manufacture high pressure and ultra high pressure boiler superheater tube, reheater tube, pipe, main steam pipe and so on. However, round tube also has certain limitations, such as under the condition of plane bending, round tube is not as good as square tube, rectangular tube bending strength, some agricultural machinery skeleton, steel and wood furniture, etc., commonly used square tube.
