1. Support Method

Setting support brackets outside the pipeline and using tools and sealing pads to plug the leakage 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 the body.

2. Pressure Sintering Method

A method of fixing a screw directly or indirectly on the pipeline to block leaks in equipment and pipeline is called the top pressure method. This method 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 sealant pad in place with a clamp band (clamp) is called the clamp band method.

4. Sintering method

A method of sealing leaks by tightly pressing a sealing washer and cover plate against the inner or outer surface of a hole, known as the cover plate method. This approach is suitable for sealing leaks in low-pressure, easily manipulated pipelines.
