1. Leak detection
First, you need to determine the location of the leak. You can locate the leak by observing the wet marks on the surface of the pipe, listening to the sound of the leak, using leak detection instruments, etc.
2. Stop operation
If possible, stop the delivery of the medium in the pipeline to reduce the leakage and reduce the difficulty of handling.
3. Empty the pipeline
Before handling the leak, try to empty the residual medium in the pipeline to prevent further leakage and pollution during the repair process.
4. Surface cleaning
Clean up the dirt, debris and water stains around the leak point to ensure that the repair area is clean and dry.
5. Assess the extent of damage
Carefully check the leak point and the surrounding pipes to determine the scope and extent of the damage, and judge whether it is a small local damage or a large area of damage.
6. Choose a repair method
If it is a small leak hole or crack, the following methods can be used:
Patch repair: Use a special HDPE patch material and stick it to the leak by heating or adhesive.
Clamp sealing: Install a special clamp and tighten the bolts to compress the leaking part to achieve sealing.
For larger area damage or serious welding defects:
Cut off the damaged part: Use professional tools to cut off the damaged pipe section, and then re-weld it.
7. Repair operation
Perform specific operations according to the selected repair method. When performing heating welding, ensure that the parameters such as temperature, pressure and time are correct.
8. Check the repair effect
After the repair is completed, re-deliver the medium into the pipeline, and closely observe and test the repaired part to ensure that there is no more leakage.
9. Record and summarize
Keep a detailed record of the process, cause and measures taken for leak handling, so as to refer to and summarize experience in the future to prevent similar problems from happening again.
