🧿1. What to do if a high-pressure water pipe leaks? (Emergency Procedures)

When a high-pressure water pipe leak is discovered, it is crucial to remain calm and follow the steps below:

1. Report and establish a cordon immediately:
Immediately report the leak to the control room, superiors, or safety department, describing the leak's location, size, and severity.

Quickly establish a cordon or warning sign around the leak area to prevent unauthorized personnel from approaching and avoid personal injury from the high-pressure water jet.

2. Safely isolate and decompress the pipe:

The most critical step: Contact the control room and close the valves upstream and downstream of the leaking pipe section to isolate it from the system.

If the system allows, open the drain or vent valve to slowly decompress the isolated pipe section. Strictly avoid performing any maintenance work while the pipe is under pressure! Decompression completely dissipates the energy of the high-pressure water and is essential for subsequent repair safety.

Confirm that the pressure in the pipe has dropped to zero.

3. On-site Assessment:
Only after the pressure has been relieved can a qualified professional approach for inspection. Assess the cause of the leak (is it corrosion perforation, weld cracking, or mechanical damage?), the extent of the damage, and its scope.
4. Develop a repair plan:
Based on the assessment results, select the most appropriate repair method (such as welding repair, using pipe leak repair clamps, replacing pipe sections, etc.).
5. Perform repair and restoration:
After completing the repair in accordance with safety procedures, slowly open the valve and perform a pressure test and leak detection on the repaired area. Once confirmed, resume normal operation.

🧿II. Risks of High-Pressure Pipeline Repair

High-pressure pipeline repair is a high-risk operation. The main risks include:

1. High-pressure fluid impact injury:
This is the greatest risk. Failure to completely relieve pressure or internal valve leakage can cause a sudden ejection of high-pressure water (or other media). This has a strong cutting force and can cause serious personal injury or even death.
2. Hazardous media:
If the pipeline is transporting high-temperature, toxic, corrosive, or flammable or explosive media, leaks and the repair process can cause secondary hazards such as burns, poisoning, chemical burns, fire, or explosion. 3. Risks in the Working Space:
Repairs are often conducted in confined spaces such as tunnels and pipe corridors, which present risks such as oxygen deficiency, toxic gas accumulation, and collapse.
4. Risks in Electric Welding:
Traditional welding repairs can cause fires, electric shock, arc burns, and fume poisoning.
5. Risks in Structural Integrity:
If the pipe wall has become extensively thinned due to corrosion, simple repair welding may not be able to withstand the pressure or may create new weaknesses in the heat-affected zone, leading to secondary leaks or bursts.
6. Long Production Downtime and Significant Economic Losses:
The traditional process of shutting off water, draining, welding, cooling, and refilling water is extremely time-consuming, resulting in prolonged downtime of the production line or water supply system and significant economic losses.

🧿3. Advantages of Using Pipe Leak Repair Clamps

Pipe leak repair clamps (also known as leak repair clamps or pipe patchers) are devices specifically designed to quickly repair pipe leaks. To address the aforementioned risks and challenges, it offers the following significant advantages:

1. Fast and efficient, significantly reducing downtime:
The installation process is simple and quick, typically taking only a few minutes to dozens of minutes, several times or even dozens of times faster than traditional welding. This minimizes losses caused by production downtime.

2. Capability for hot-dip plugging (specific types):
Note: Not all leak repair clamps are suitable for hot-dip plugging, but there are specially designed hot-dip plugging clamps. Under specific conditions and professional operation, temporary or permanent repairs can be achieved without completely shutting down the system, which is crucial for critical systems that cannot be shut down (such as main water supply mains and chemical mains).

3. High safety:
It eliminates the risk of fire and explosion associated with hot work (welding).
As long as installation is carried out in strict accordance with regulations, isolation and pressure relief are followed before installation, eliminating the risk of high-pressure fluid shock.

4. Wide range of applications:
It can be used to repair pipes of various materials, including steel, cast iron, PVC, and PE pipes.
It effectively repairs various types of leaks, including punctures, cracks, breaks, and thread damage. 5. Easy to operate, no special skills required:
Installation typically requires only common tools (such as wrenches), requiring far fewer skilled operators than high-pressure welders, making it easy to deploy and implement in emergency response situations.
6. Flexible sealing and excellent reliability:
Using a rubber sealing ring and bolted fastening to generate a sealing pressure, this system offers excellent flexibility and compensating capabilities, adapting to even minor pipe deformation and vibration.
7. Cost-effectiveness:
While the purchase cost of a single leak repair clamp may be high, the overall cost-effectiveness is significant when considering the reduced downtime, labor costs, and safety risks.

Conclusion:

For emergency repairs on high-pressure pipelines, pipe leak repair clamps are the preferred, efficient, and safe solution for modern industrial maintenance. It is recommended that all units involved in the operation of pressure pipelines should keep leak repair clamps suitable for the pipe diameter and pressure as standing emergency supplies, and provide operation training to maintenance personnel to ensure that problems can be solved quickly and safely in the event of sudden leaks.
