High-pressure boiler tube bending treatment method

Reasons for high-pressure boiler tube bending

High-pressure boilers are one of the common mechanical equipment in industrial production. Their pipes are tightly connected and can withstand high-temperature steam under high pressure. However, during use, due to various reasons, seamless pipes may be bent and deformed to varying degrees, resulting in unstable equipment operation and even leakage and other faults. The main reasons for high-pressure boiler tube bending are as follows:

2. Pipe deformation and damage caused during transportation and installation.

3. Pipe deformation caused by long-term use or external force, such as deformation caused by expansion, contraction or vibration.

High-pressure boiler tube bending treatment method

High-pressure boiler tubes need to be handled in time after bending, which can not only extend the service life of the equipment, but also improve work efficiency and avoid accidents caused by pipe bending. The following are several methods for high-pressure boiler tube bending treatment:

1. Heat treatment method

The heat treatment method is to heat the bent pipe in a high temperature environment to soften it and then bend it. This method can effectively reduce the stress of the pipe wall after heat treatment, but it needs to be cooled after bending to avoid cracks in the pipe.

2. Cold bending method

The cold bending method is to process the bent pipe into a specific size and shape, perform local processing at its bend, and apply a large force around it. This method is simple to operate, but you need to pay attention to the cold bending angle and the amount of force applied.

3. Hot bending method

The hot bending method is to hit the pipe to be bent with an iron or heat it and knead it, so that the pipe can be hot-bent to ensure that the pipe will not break or deform. However, this method needs to be carried out at high temperature, and safety issues need to be paid attention to.

The above methods can all be used for the treatment of high-pressure boiler tubes after bending, but they need to be selected according to the specific situation and the material of the pipe. 

Precautions

1. Operate in strict accordance with the operating procedures and operating procedures.

2. For complex pipe bending problems, you can seek the help of professional technicians.

3. Before operation, the equipment and tools must be checked to avoid operational risks.

4. For pipes that have already reached the end of their service life, you can consider replacing safer pipes.

5. During operation, you need to pay attention to the cleanliness and safety of the construction site to avoid other accidents.

Conclusion

High-pressure boilers are indispensable mechanical equipment in the production process. If the pipe bending problem is not handled properly, it will have a serious impact on the safety and production efficiency of the equipment. Therefore, when facing the problem of high-pressure boiler tube bending, it is necessary to handle it according to the specific situation and pay attention to safety and standardization during operation. Through the introduction of several high-pressure boiler tube bending treatment methods, the pipe bending problem can be better solved to ensure the stable operation of the equipment.
