Round pipe is a steel with two ends open and hollow concentric circle section, and its length is larger than the surrounding steel. It can be used in pipeline, thermal equipment, machinery industry, petroleum geological drilling, container, chemical industry and special purposes.
Basic Information
Method of representation
Round tube specifications are expressed in terms of external dimensions (such as outer diameter or side length) and inner diameter and wall thickness. They range in size from very small capillaries to large round steel tubes with diameters of several meters.
Main Use
Round pipe can be used in pipeline, thermal equipment, machinery industry, petroleum geological drilling, container, chemical industry and special purposes.
Manufacturing process
classification
According to the production method can be divided into seamless round pipe and welded round pipe.
Seamless steel pipe manufacturing process
Tube billet heating - inspection - skin - - - perforation, pickling, grinding, dry lubrication, welding head, cold drawing, solid solution treatment, pickling, pickling passivation - inspection
Welding steel pipe manufacturing process
Strip steel -- Inspection -- Shear -- sizing -- Qualitative -- welding -- grinding (seamless)-- sizing -- inspection
