Reasons for water leakage in copper pipe fittings
2023-05-20
1. The main reason for this is that the materials used in the production of copper pipes are different between China and foreign countries, because foreign standards emphasize the advantages of good welding performance, corrosion resistance, and high strength, while the materials used in China cannot achieve this;
2. There are problems with fitting tolerances both domestically and internationally. In fact, domestic standards are not as good as foreign standards, and there may be significant errors in copper pipe fittings. This may result in copper pipe inserts not being able to be inserted into the pipe fittings, and the integrity and stability of the welding joint may also be poor, leading to water leakage and other phenomena;
3. In terms of welding process, too large fit gap causes the workers to be unable to use the brazing process correctly. Instead, they use poor fluidity welding rod and overlay welding to seal the weld crater. This weld crater is prone to water leakage in the event of water pressure fluctuations and thermal expansion.
So through the above simple analysis, I believe you have gained some basic understanding of the application of copper pipe standards and the reasons for copper pipe leakage. There are some situations that can be solved, but some are difficult to solve. Therefore, when selecting products, it is important to pay attention.
