Description:Precision steel pipe appearance color and gloss
Precision steel pipes are usually silver-white or metallic, which is because they are mainly composed of iron, carbon and other elements, and are processed by specific production processes.
The surface of high-quality precision steel pipe should have a metallic luster, showing a uniform and bright appearance.
2. Surface quality
Finish: The inner and outer surfaces of precision steel pipes should have a high finish, without obvious defects such as oxide film, rust, inclusions.
Precision: The dimensional accuracy of precision steel pipe is high, and the dimensional parameters such as inner and outer diameter and wall thickness meet the design requirements, and have good dimensional stability.
Surface scars: high-quality precision steel pipe surface should have no scars, scratches, pitting and other defects. These defects may be caused by improper production processes, poor raw material quality or damage during transportation.
3. Shape and structure
Straightness: The straightness of precision steel pipe is good, without obvious bending or deformation.
Section shape: The section shape of precision steel pipe is usually round, and the inner and outer walls are smooth and uniform. Some special purpose precision steel pipes may have sections of other shapes, such as squares, rectangles, etc.
No cracks: there should be no cracks, inclusions and other defects on the surface and inside of the precision steel pipe to ensure that it has sufficient strength and toughness during use.
4. Identification and packaging
Identification: The precision steel pipe is usually marked with the manufacturer, specifications, models, production date and other identification information, so that users can identify and trace.
Packaging: High-quality precision steel pipes are properly packaged before leaving the factory to prevent damage during transportation and storage. Packaging materials should have certain protective properties, such as moisture, rust and so on.
In summary, the appearance of precision steel pipe has the characteristics of silver or metal color, metal luster, high finish, high precision, no scratches and so on. These characteristics make precision steel pipes have a wide range of application prospects in the manufacturing industry, especially in areas requiring high precision, high strength and corrosion resistance.
parameters
The inner diameter and wall thickness of the precision steel pipe are its basic dimension indicators. The inner diameter indicates the diameter inside the steel pipe, while the wall thickness indicates the thickness of the steel pipe wall. Common precision steel pipe diameter ranges from a few millimeters to tens of millimeters, the wall thickness range is also different, depending on the specifications and uses of the steel pipe. For example, the nominal inner diameter of some precision steel pipes is 1080mm, and the wall thickness range is 0.38mm.
Ii. Tolerance
Tolerance is an important index of the dimensional accuracy of precision steel pipe, which reflects the deviation between the actual size and the theoretical size of the steel pipe. The tolerances of precision steel pipes include dimensional tolerances and shape tolerances.
Dimensional tolerance: refers to the difference between the actual size and the theoretical size of the inner and outer diameter of the steel pipe. For ordinary precision steel pipes, the outer diameter tolerance is usually ±0.05mm. However, in the case of higher accuracy, such as aerospace, medical equipment and other fields, the outer diameter tolerance can reach ±0.025mm or even smaller. The outer diameter tolerance of special precision and special precision steel pipes can be controlled within ±0.01mm or even ±0.005mm. The control of the inner diameter tolerance is equally important, which affects the flow efficiency and stability of the fluid inside the steel pipe, and in general, the inner diameter tolerance will be controlled within a similar range to the outer diameter tolerance.
Shape tolerance: refers to the deviation between the shape of the inner and outer surfaces of the steel pipe (such as roundness, straightness, etc.) and the ideal shape. For high-quality seamless precision pipes, the roundness tolerance is usually small to ensure the stability and reliability of the steel pipe in the process of rotation, connection, etc. Straightness tolerance reflects the deviation between the actual shape of the inner and outer surfaces of the steel pipe and the ideal straight line, and this tolerance is also crucial for the stability and reliability of the steel pipe in the length direction.
