Hafe joint is a pipeline repair device, and the socket Hafe joint is a device for repairing water leakage at the joint of two pipes. Hafe joint is a device for repairing parts other than the joint. The device has a simple structure consisting of only two bodies and two rubber pads. It is easy to install and can be repaired by simply fitting the two bodies together at the leakage point and tightening the nut. This device can save time when water is cut off and reduce repair costs.

 

Haval section performance characteristics:

 

This product combines two technologies: plastic contact sealing and elastic contact sealing, and is suitable for pipelines of various materials, effectively controlling the leakage problem of the medium.

 

2. The on-site use effect is good, and it can achieve no leakage. It adopts a block structure, with fast on-site construction speed, no need to stop water, small excavation volume, and only a small work pit needs to be excavated to operate, saving a lot of manpower, material resources, and time, and quickly achieving the purpose of plugging the leak.

 

3. The working pressure of this product is 0.25-1.0MPa, suitable for repairing water leakage in various cast iron pipes, cement pipes, and PVC pipes. The product specifications are complete and suitable for various national standard pipe diameters. Non standard can be processed and customized separately.

 

4. No need to shut down or isolate the system.

 

5. No pressure relief is required for the system.

 

6. Save a lot of energy and manpower.

 

7. Greatly reduces the power loss caused by equipment isolation or shutdown.

 

8. Reduced socio-economic losses.

 

Haff's principle:

 

Based on the sealing mechanism of solid sealing materials in liquid media under dynamic conditions, the pressurized Haff joint is equipped with specialized equipment at the leakage site. Using the chamber formed between the sealing site and the specialized equipment, a dedicated high-pressure glue injection tool is used to inject sealant into the chamber and fill the entire chamber space, so that the squeezing force of the sealant is balanced with the pressure of the leakage medium, establishing a new sealing structure to block the various channels of the leakage pores and prevent the leakage of the medium.
