1. Support Method
Setting up supports outside the pipeline and using tools and gaskets to plug the leak is known as the support method. This method is suitable for plugging leaks in larger pipelines and is adopted due to the inability to secure it on the main body.
2. Pressure Sintering Method
A method for plugging leaks at equipment and pipeline openings by fixing a screw directly or indirectly on the pipeline, known as the top-pressure method. This technique is suitable for plugging leaks such as sand holes and small holes on medium and low-pressure pipelines.
3. Clamp method
The method of stopping leaks by securing a sealing washer in place with a clamp (also known as a clamp) is called the clamp method.
4. Cap Sealing Method
A method of sealing leaks by tightly pressing a gasket and cover plate onto the inside or outside of a hole, known as the cover plate method. This method is suitable for sealing leaks in low-pressure pipelines that are easy to operate.
