1. Support Method
Setting up supports outside the pipeline and plugging leaks with tools and sealing washers is known as the support method. This method is suitable for sealing leaks in larger pipelines and is adopted due to the inability to secure it to the body.
2. Pressure Sintering Method
A method of sealing leaks on equipment and pipelines by fixing a bolt directly or indirectly on the pipe, known as the top-pressure method. This technique is suitable for sealing 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. Capsule method
A method of sealing leaks by tightly pressing a gasket and cover plate against the inside or outside of a hole, known as the cover plate method. This method is suitable for low-pressure, easily operable pipeline leak sealing.
