Plugging steam pipelines under pressure is a very technically demanding job that requires professional operations. In industrial production, steam pipes are one of the common equipment, and due to the particularity of their working environment, pipelines often have various leakage problems. In order not to affect the production schedule and ensure safety, leak plugging under pressure has become a very necessary technical means.

First, the principle of steam pipeline leakage plugging under pressure.
Leak plugging technology under pressure refers to a technology that seals the leakage part under the condition of maintaining the pressure of the medium in the pipeline. The principle is mainly based on the selection of sealing materials and rapid plugging equipment, so that the leakage part can be effectively plugged in a short time to prevent further leakage of the medium.
Second, the method of plugging the leakage of the steam pipeline under pressure.
1.Glue injection method: The sealant is injected into the leakage part through the glue injection gun, so that the sealant can quickly fill the void under the action of pressure to achieve the purpose of stopping leakage. This method is suitable for small to medium-sized leaks and requires prior installation of a glue nozzle on the pipe.
2.Magnetic pressure method: the magnetism of the magnet is used to adsorb the sealing gasket on the leakage part, and the gasket is fixed by tightening the bolt, so as to achieve the leakage prevention effect. This method is suitable for small to medium-sized leaks and is suitable for round or oval leak holes.
3.Mechanical plugging method: using a plugging device composed of various fixtures and sealing materials, applying pressure to the leakage part through the clamp and fixing it, and then using the sealing material to fill the void to achieve the purpose of stopping leakage. This method is suitable for large leaks or irregularly shaped leaks.
3. Precautions for plugging leaks under pressure in steam pipelines.
1.Before the pressure plugging operation, the leakage site must be fully understood, including the leakage medium, temperature, pressure and other parameters. Select the appropriate plugging method and material according to the actual situation.
2.The operation of plugging leaks under pressure needs to be carried out by professionals, and non-professionals are prohibited from operating without authorization. At the same time, the operator must be professionally trained and familiar with the use of various plugging techniques and equipment.
3.Safety measures must be taken when plugging leaks under pressure, such as wearing protective clothing and protective glasses. At the same time, it is necessary to ensure the safety of the operation site and avoid accidents.
4.After the pressure plugging operation is completed, it needs to be inspected and accepted to ensure that the leak has been effectively controlled. At the same time, it is necessary to maintain and maintain all kinds of equipment used in the operation process to ensure its normal operation and use effect.
In short, plugging steam pipelines under pressure is a very technically demanding job that requires professional personnel. In practical application, it is necessary to select appropriate plugging methods and materials according to the actual situation, and strictly abide by the operating procedures and safety measures. Through the application of pressure plugging technology, the leakage problem of steam pipelines can be effectively solved and the normal operation and safety of industrial production can be guaranteed.
