Treatment Methods For Boiler Tube Leakage

Causes of boiler tube leakage

1. Aging of pipelines: After the boiler has been used for a long time, the pipelines will age due to corrosion, wear and other reasons, which will cause pipeline leakage.

2. Too high temperature: The boiler temperature is too high, which will also cause the pipeline to loosen and age, resulting in leakage.

3. Installation problems: Poor installation, untightened and loose pipeline connections, etc. may also cause leakage.

4. Pipeline extrusion and deformation: Pipe extrusion or deformation will also cause cracks in the pipeline and leak.

5. Boiler water temperature is too high: The boiler water temperature is too high, which is also one of the reasons for boiler tube leakage. Excessive water temperature will increase the pressure on the pipeline and cause the pipeline to crack.

Emergency treatment methods

1. In extreme emergencies, it is necessary to stop the furnace immediately for treatment, and close the water valve and gas valve in time to avoid further leakage accidents.

2. Find the location of the leak: The leak can be found based on the sound of the leak, the bubbling of the pipeline and the connector, so as to better repair it.

3. Use soil or cement to plug the leak: For small leaks, you can use soil or cement to plug the leak and cover it with dry soil to reduce the extent of the leak.

Methods for dealing with boiler tube leaks

1. Replace the leaking pipe: If the leak is serious, it is recommended to replace the leaking pipe directly. This method is more thorough and can eradicate the leak problem, but the cost is relatively high.

2. Chemical lap treatment: Chemical lap treatment is a relatively simple method, which is suitable for situations where the pipeline leak is relatively small. Use chemical lap materials to fill the leaks in the pipeline so that the leaks do not continue to expand.

3. Welding treatment: Welding treatment is a relatively effective method, but you need to pay attention to some details and risks. First, you need to choose the appropriate welding materials and methods. Secondly, you need to pay attention to the temperature and environment around the pipeline to prevent safety accidents such as fire during welding. In addition, when performing welding treatment, you need to follow the specifications and conduct necessary inspections and tests to ensure that the welded pipeline can work normally.

Welding treatment skills

When welding boiler pipes, you need to pay attention to the following aspects:

1. Cleaning of pipes: Before welding, you need to clean up the debris around the pipes to ensure that there are no impurities affecting the welding effect during welding.

2. Choose the right welding materials and methods: Choosing the right welding materials and methods can ensure the welding effect. Generally, MIG gas shielded welding or TIG argon arc welding is selected for boiler pipe welding.

3. Protection around the pipe during welding: When welding, the area around the pipe needs to be protected from damage. You can use materials such as fire blankets to cover the area around the pipe.

4. Inspection and testing after welding: After welding, the weld needs to be inspected and tested to ensure that there are no cracks and water leakage at the weld of the pipe.

When welding boiler pipes, you need to pay attention to safety and skills. If the technology and conditions do not allow, it is recommended to choose other appropriate treatment methods.

Completely eliminate the cause of the leakage

1. Update the pipeline: For aging pipelines, new pipelines need to be replaced to avoid further leakage.

2. Improve installation: For problems such as poor installation, untightened or loose pipe connections, thorough inspection and improvement are required to ensure the normal operation of the pipes.

3. Improve maintenance level: Strengthen daily inspection and maintenance work, timely discover and deal with boiler problems, and avoid escalation of problems.

Precautions

1. Don't be impatient when dealing with boiler tube leakage. Analyze calmly and take corresponding countermeasures.

2. Strictly abide by safety operating procedures to ensure the safety of personnel and equipment.

3. If you cannot judge or deal with the boiler tube leakage problem, you should contact professional technicians in time for treatment.

In short, for the boiler tube leakage problem, we must deal with it in time and take corresponding measures to solve it, avoid further expansion of the leakage problem, and ensure the safety of personnel and equipment.
