As an important heat exchange equipment, the heat exchanger sometimes leaks during operation, which will have a serious impact on its performance and normal use. The following is a detailed analysis of the causes of internal leakage of the heat exchanger.

Material problems are an important factor leading to internal leakage. If the selected heat exchange tube and other materials are of poor quality, have defects or are not corrosion-resistant, they are prone to breakage, cracks, etc. during long-term use, thus causing internal leakage.

Imperfections in the manufacturing process may also cause internal leakage. For example, if there are welding defects during the welding process, the weld is not firm or there are pores, slag inclusions, etc., these weak points are prone to leakage under pressure and temperature changes when the equipment is running.

The heat exchanger will be subjected to certain pressure and temperature changes during use. If the pressure fluctuation is too large or the temperature change is too drastic, the structure of the heat exchanger may be deformed or fatigued, which may cause internal leakage over time.

Corrosion is also one of the common reasons. Whether it is the corrosiveness of the medium itself or the corrosion caused by external environmental factors, it will gradually erode the components of the heat exchanger, reduce its strength and cause internal leakage.

Improper operation may also cause internal leakage. For example, improper on and off sequence, excessive flow or pressure shock, etc. may cause damage to the heat exchanger.

In addition, long-term operation and lack of timely and effective maintenance will cause some parts of the heat exchanger to age and wear, which may also become a potential hidden danger of internal leakage.
