Differences in performance between mechanical steel pipes and ordinary steel pipes

There are significant differences in performance between mechanical steel pipes and ordinary steel pipes, which are mainly reflected in the following aspects:

1. Processing accuracy and surface quality

Mechanical steel pipes: have extremely high processing accuracy, extremely high inner and outer diameter dimensional accuracy, and uniform wall thickness. Its surface smoothness and dimensional control are also more precise, which can meet the high requirements for precision manufacturing.

Ordinary steel pipes: The dimensional accuracy and surface finish are relatively low, and there is a certain tolerance range. The surface may be rough and further processing is required to achieve the required accuracy and finish.

2. Mechanical properties

Mechanical steel pipes: have high tensile strength, yield strength and good elongation. Able to withstand greater pressure and load while maintaining good toughness and fatigue resistance. These properties make precision steel pipes more stable and reliable when subjected to complex stresses and deformations.
Ordinary steel pipes: Although they also have certain strength and toughness, their mechanical properties are weaker than precision steel pipes. When subjected to greater pressure and load, additional reinforcement or protection measures may be required.

3. Corrosion resistance

Mechanical steel pipe: Made of high-quality materials and subjected to special surface treatments such as phosphating anti-rust treatment. These treatments improve the corrosion resistance of steel pipes, allowing them to be used for a long time in harsh environments without being easily corroded and damaged.
Ordinary steel pipes: Corrosion resistance is relatively poor, especially in corrosive media such as hydraulic oil containing a variety of additives. Long-term use can easily lead to corrosion, thinning and even perforation of the inner wall of the pipe.

4. Diversity of specifications and materials

Mechanical steel pipes: Products of different specifications and materials can be customized according to customer needs to meet the needs of various application scenarios. Its diverse specifications and wide range of materials provide users in different fields with more choices and flexibility.
Ordinary steel pipes: Although there are also certain specifications and material options, their selection range is relatively limited compared to precision steel pipes.

Conclusion:

Mechanical steel pipes are superior to ordinary steel pipes in terms of processing accuracy and surface quality, mechanical properties, corrosion resistance, and diversity of specifications and materials. These performance advantages enable mechanical steel pipes to perform well in a variety of application scenarios and become the preferred material for many industries. However, the specific choice of steel pipe still needs to be comprehensively considered based on the actual application scenarios and needs.
