1. Support method

Supporting method, which involves setting up supports outside the pipeline and sealing leaks using tools and gaskets. This method is suitable for plugging leaks in larger pipelines and is used when it's not possible to secure the pipeline itself.

2. Pressure Sintering Method

A method of sealing leaks in equipment and piping by directly or indirectly blocking the leak points with a bolt fixed on the pipeline is known as the top-pressure method. This method is suitable for sealing leaks such as sand holes and small holes in 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 referred to as the clamp method.

4. Capsule Sealing Method

A method of sealing leaks by tightly pressing a gasket and cover plate against the inner or outer surface of a hole, known as the cover plate method. This technique is suitable for low-pressure applications and is convenient for sealing leaks in pipes.
