You know seamless is raw material for many fields. Our precision seamless tube is used for gas spring products, auto and motorcycle such as bushing and shock absorber, and hydraulic oil. So we also need know the factor for how to impact the precision of seamless steel tube.

The cross section of the seamless steel pipe has a plurality of indexes, namely: outer diameter, wall thickness, inner diameter, wall thickness difference, concentricity, and the like. 

Commonly used is generally speaking about the outer diameter and wall thickness, but for the mechanical, automotive and other industries, most of the requirements of the inner, outer diameter and concentri city, then the wall thickness is not required, this pipe is only cold drawn or cold rolled For the production of steel pipes, the deviation of the inner diameter is usually +-0.1mm, and the higher is +-0.05 or even +-0.02mm. 

Seamless steel tubes have hollow sections and are used in large quantities as pipes for transporting fluids, such as pipes for transporting petroleum, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe is lighter in weight when it has the same bending and torsional strength. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycles. Steel frames and other steel scaffolding used in construction are used to manufacture ring-shaped parts, which can improve the material utilization rate, simplify the manufacturing process, save materials and processing man-hours, and have been widely used in steel pipes.
