1. Water welding with pressure
This method is suitable when the pipeline leaks, the pipe itself is in good condition without serious rust and other defects, and the pressure in the pipe is small, so it can be directly welded.
2. Self-made pipe clamp plugging method
This method is suitable for methods such as relatively narrow pipes, which are not easy to plug and plug leaks, and the pipe diameter is small.
3. Screw cap plugging method
This method is suitable for pipelines with relatively large internal pressure and large diameter.
4. Pipeline tacking and plugging method
The steam pipeline leak plugging method under pressure is suitable for pipelines with high pressure in the pipe, relatively wide position, and small pipe diameter.
