Characteristics and advantages of round tubes

Round tuberefers to Steel with open ends and hollow concentric cross-section, and its length is relatively large compared to the perimeter.

It can be used for pipelines, thermal equipment, mechanical industry, petroleum geological drilling, containers, chemical industry and special purposes.
Representation method
The specifications of round tubes are expressed by external dimensions (such as outer diameter or side length) and inner diameter and wall thickness. Its size range is very wide, from capillaries with very small diameters to large round Steel Pipes with diameters of several meters.
Main uses
Round tubes can be used for pipelines, thermal equipment, mechanical industry, petroleum geological drilling, containers, chemical industry and special purposes.
Manufacturing process
According to the production method, it can be divided into seamless round tubes and welded round tubes.
Seamless steel pipe manufacturing process
Pipe blank - inspection - peeling - inspection - heating - perforation - pickling - grinding - lubrication and air drying - welding head - cold drawing - solution treatment - pickling - pickling passivation - inspection
Welded steel pipe manufacturing process
Strip steel - inspection - shearing - length - qualitative - welding - grinding (seamless) - length - inspection
Seamless steel pipe material ：10#, 20#, 35#, 45#, 16Mn, 27simn, 20G, 40Cr, etc.
Welded steel pipe material ：Q195A, Q215A, Q235A, Q345A, etc.

Common uses of Round Pipes include:
Pipeline: used to transport water, oil, gas and other media.
Thermal equipment: used for boilers, heat exchangers and other equipment.
Mechanical industry: used for shafts, gears and other parts.
Petroleum geological drilling: used in the drilling process.
Container: used to manufacture various containers.
Chemical industry: used to produce chemical products.
Special uses: such as gun barrels and shells in the military industry.
Advantages of round tubes:
High strength: round tubes have high strength and can withstand greater pressure and stress.
Light weight: the density of round tubes is relatively low, which can reduce the weight of the structure.
Corrosion resistance: round tubes made of certain materials (such as stainless steel) have good corrosion resistance.
Easy to process: round tubes can be welded, bent, cut, etc.
Classification of round tubes:
Material: steel tubes, stainless steel tubes, aluminum tubes, etc.
Connection method: threaded connection, welding connection, etc.
Galvanized treatment: galvanized round tubes are used for fire protection engineering, steel structures, etc.
