Copper sleeve thermal shrinkage rate standard

The standard for thermal shrinkage rate of copper sleeves should be between 0.5% and 2%. The reason why the standard shrinkage rate of copper sleeves during hot installation should be between 0.5% and 2% is as follows:

1. The standard for thermal shrinkage rate of copper sleeves should be between 0.5% and 2%, mainly because the shrinkage rate within this range can meet the requirements of copper sleeve use, while also ensuring the stability and controllability of the production process.

2. If the shrinkage rate of the copper sleeve is too small, it may lead to loose installation or failure; If the shrinkage rate is too large, it may cause the copper sleeve to become too tight or break. Therefore, choosing an appropriate range of shrinkage rate is very important.

3. In addition, a range of 0.5% to 2% is also a common standard, which can facilitate comparison and communication between different manufacturers. Meanwhile, this scope can also meet the needs of most application scenarios. So the standard for the shrinkage rate of copper sleeves during hot installation should be between 0.5% and 2%. The thermal shrinkage rate of copper sleeve refers to the proportion of changes in the size of the copper sleeve during the heating process. The specific values will be affected by different factors, such as material composition, temperature changes, processing technology, etc.
