The quality inspection standards for precision mechanical tubes mainly include the following aspects:
1. Appearance quality: Appearance quality is one of the important indicators for measuring the standards of precision mechanical tubes. Including requirements such as appearance without defects, surface finish, no scratches, and no oxidation.
2. Dimensional accuracy: The dimensional accuracy of precision mechanical tubes is a key indicator for measuring their quality. This includes the degree and tolerance requirements of dimensions such as outer diameter, inner diameter, and wall thickness. The dimensional tolerance of inner and outer diameters should be strictly controlled within 0.2mm to ensure high-precision effects.
3. Material composition: The material composition of precision mechanical tubes must comply with standard specifications to ensure that the quality of the raw materials used meets the requirements.
4. Physical properties: Physical property testing is an important link in ensuring the quality of precision mechanical tubes. Including tests in terms of strength, toughness, tensile strength, hardness, impact performance, etc.
5. Chemical composition: The detection of chemical composition is used to verify whether the content of various elements in precision mechanical tubes meets the standard requirements and exclude the presence of impurities.
6. Temperature and pressure performance: For precision mechanical tubes used in special environments, it is also necessary to verify whether their high temperature resistance, low temperature resistance and pressure resistance meet the requirements.
7. Other special requirements: According to the needs of different industries, there may also be special quality requirements, such as corrosion resistance, sealing performance, non-destructive testing, etc.
In addition, precision mechanical tubes generally strictly abide by relevant quality inspection standards, such as ISO9001 quality management system certification, ISO14001 environmental management certification, etc., to ensure the quality of the product and meet environmental requirements. At the same time, the quality inspection of precision mechanical tubes also needs to use advanced inspection equipment and methods, such as microscopes, optical projectors, tensile machines, hardness testers, etc., to ensure the accuracy and reliability of the test results.
Advantages of precision mechanical tubes:
Precision mechanical tubes are a kind of high-precision and high-reliability pipe fittings, which are widely used in various industrial fields. The following are some advantages of precision mechanical tubes:
