1. Support Method

Setting support brackets outside the pipeline and plugging leaks using tools and gaskets is known as the support method. This technique is suitable for sealing 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 plug leaks in equipment and pipeline is called the top pressure method. This method is suitable for plugging leaks at sand holes, small holes, and other leak points 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. Caps 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 method is suitable for sealing leaks in low-pressure, easily manipulated pipelines.
