What is precision steel tube?
Precision steel tube is a high-precision steel pipe material processed by
cold drawing or cold rolling. Due to the high dimensional accuracy of precision steel tubes, the smoothness of the inner and outer surfaces of the steel pipes, there is no oxide film on the inner and outer surfaces of the steel pipes after heat treatment, there are no cracks in the expansion and flattening of steel pipes, and no deformation in cold bending. They can withstand high pressure and can be used for various complex deformations and mechanical processes. Deep processing is mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless tubes or welded pipes.
Features of precision steel tubes:
1. Smaller outer diameter.
2. High precision and can be used for small batch production.
3. The cold-drawn finished product has high precision and good surface quality.
4. The cross-sectional area of the steel pipe is more complex.
5. The performance of steel pipe is superior and the metal is denser.

Differences between Precision Steel Tube and Seamless Steel Tube:
1. Different name coverage
Precision steel tubes can be divided into
welded steel tubes and
seamless steel tubes according to different forming methods. Precision steel tubes are steel pipes that are defined only by their own tolerance size, smoothness, roughness and other technical requirements coefficients.
2. Different molding methods
Precision steel tube: Generally formed by cold drawing or cold rolling, the processing technology can often control high precision and high finish.
Seamless steel tube: Generally refers to the steel pipe formed by hot rolling and perforation of round steel. If the tolerance, smoothness, roughness and other requirements are not specified, it is often defaulted to general hot-rolled or cold-drawn seamless steel pipe.
3. Different accuracy and surface quality
The main characteristics of precision steel tubes are high precision, good smoothness and excellent surface quality. Precision steel tubes can be seamless steel pipes, but seamless steel pipes are not necessarily precision steel tubes. This mainly depends on the dimensional accuracy, surface roughness, smoothness, etc. of the steel pipe.
Ordinary seamless steel tubes often refer to hot-rolled or cold-drawn seamless steel tubes with no special surface requirements. The surface of steel pipes is often dark brown, accompanied by oxide scale or floating rust.
4. Different application scopes
Precision steel tube: It can often be directly used in mechanical parts, automobile and motorcycle parts, precision instruments, aviation, aerospace and other fields with high precision requirements.
Ordinary seamless steel tubes: often used as raw materials in the field of machining and as fluid pipes, gas pipes, etc. in chemical industry, electric power and other fields.
5. Steel pipe diameter sizes cover different ranges
Seamless steel tubes: Large, medium and small diameters are often the main ones, and large and medium diameters are more in stock.
Precision steel tubes: mostly medium and small diameters, among which small diameter precision steel pipes are more in stock.
6. Steel pipe customization requirements are different
Seamless steel tube: The tolerance requirements of seamless steel tubes only need to meet the national standard. The minimum order quantity for hot rolling is often higher. The general minimum order quantity ranges from dozens of tons to hundreds of tons according to different calibers.
Precision steel tube: Precision steel tube has higher tolerance requirements and generally needs to be customized according to the customer's tolerance range requirements. The minimum order quantity is flexible, ranging from a few tons to dozens of tons depending on the processing accuracy and caliber size.
Conclusion:
To sum up, there are differences between precision steel tubes and seamless steel tubes in terms of name coverage, forming methods, accuracy and surface quality, application scope, caliber size coverage, customization requirements, etc. Understanding these differences is important for proper selection and use of steel pipe.
