How To Distinguish Precision Tube & Deep Hole Tube

Precision tube and deep hole tube are two different types of tubes. Although both have high precision and surface quality, they also have some differences in use, manufacturing process and application field.

Different materials

Precision tube and deep hole tube are different in material. Precision tube generally adopts high-precision cold-drawn steel tube, seamless steel pipe, welded steel pipe, and metal materials such as copper and aluminum. Deep hole tube often uses stainless steel and carbon steel materials, as well as steel with very high strength and hardness. Therefore, the difference in material also determines the difference in their production process.

Different precision requirements

In terms of precision, deep hole steel tube and precision tube each have their own advantages. Since precision tube is usually used to manufacture high-precision equipment or experimental equipment, its precision requirements are higher, especially the control precision requirements of diameter and wall thickness are higher. Precision tube ensures that the outer diameter and wall thickness of the pipe reach a high level of precision by accurately controlling the forming process of the tube blank. This enables precision tube to ensure the assembly accuracy and performance of components in the application of structural parts and connectors.

The precision requirements for deep hole pipes are relatively low, mainly considering the needs of their use scenarios, such as the exhaust pipes of motors. Through drilling, reaming and other processes, deep hole steel pipes can achieve a higher inner wall smoothness while ensuring the depth of the pipe. This makes the fluid less resistant during transportation, which is conducive to improving transportation efficiency.

Different manufacturing processes

The manufacturing processes of precision pipes and deep hole pipes are also different. In the production process of precision pipes, multiple processes such as precision cold drawing and precision annealing are required to ensure the high precision and high finish of the pipes. The production of deep hole pipes requires a variety of processing, including deep hole drilling, bending, polishing and other technologies to ensure its accuracy and stability.

Different functions

The functions of precision pipes and deep hole pipes are also different. Precision pipes are mainly used in precision machinery, automobile manufacturing, aviation manufacturing and other fields, such as sensors, instruments and equipment, pressure gauges, etc. Deep hole pipes are often used in high-precision fields such as oil extraction and aerospace, such as hydraulic systems, oil detection equipment, etc. It can be seen that the application fields of the two are not the same.

Summary

To sum up, although precision tubes and deep hole tubes are both metal tubes, their application fields and functions are different due to differences in production, manufacturing and use. Both deep hole steel tubes and precision tubes perform well in terms of precision, but each has its own advantages and disadvantages. Deep hole steel tubes are suitable for scenarios with high requirements for pipe depth and inner wall smoothness, while precision tubes are more suitable for applications with high requirements for pipe outer diameter and wall thickness accuracy. When choosing pipes, you should choose the appropriate material according to specific needs.
