Carbon seamless steel tube is a unique long steel product. Seamless steel tubes have a hollow cross-section and are widely used as pipes for transporting fluids, such as pipes for transporting oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, the carbon steel pipe has the same flexural and torsional strength and is lighter in weight. Carbon seamless steel tube is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, Bicycle racks and steel scaffolding used in building construction, etc.
The use of carbon seamless steel tubes to manufacture ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sets, etc., which have been widely used in the manufacture of seamless steel tubes.
Carbon seamless steel tube is also an indispensable material for various conventional weapons. Gun barrels, barrels, etc. must be made of carbon steel pipes. Seamless steel tubes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area. Due to the condition that the circumference is equal, the area of the circle is the largest, and more fluid can be transported with a round tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform, so most carbon steel pipes are round pipes.
