In short, no-dig relining is a method of repairing damaged pipes by fixing a lining into the existing damaged pipe without resorting to excavation. The Speedylight LED system can repair various types of problems within a pipe, for example:
A LED curing system is needed to change coatings and adhesive substances into an instant fixed-in-place solid by using high-intensity UV light. This is also known as a lining.
Sewertronics Speedylight LED system is the most versatile and commonly used LED curing system in the UK. As a result, the system has the ability to cure:
The liners have to be impregnated with UV Vinylester Resin before being flattened. In addition, to ensure an even and complete wet out the liner is infused with resin under controlled conditions.
Unlike traditional methods, the new system can negotiate bends of up to 90 degrees for a variety of different pipe sizes.
There are multiple benefits of the new system, which previous lining methods don't have, for instance:
In conclusion, these benefits reduce the average time at the job site dropping from on average 8 hours to 1.3m per minute. Therefore making it 5 times faster as the LED cure time corresponds directly to the length and diameter of the pipe, contrary to heat-cured solutions.
The system has 4 interchangeable curing heads. So, the change of head depends on the length/width of the pipe or the liner material.
There are 3 main methods of installing the LED system, for instance:
Firstly, the liner is filled with resin and is then inflated into the damaged pipeline.
Throughout the process, the liner is inverted so that the resin turns and is pressed against the pipe’s inner walls.
After inserting the liner, the interchangeable UV head is run through the liner to cure the resin, forming a permanent bond between the pipe and the liner.
This method of installation must have 2 accessible manholes, one on either side of the damaged pipeline.
The method includes tying a rope or cable to a high-pressure water jetter to make its way from one side of the pipe to the other. The rope/cable is then hooked or tied around one end of the liner, and the high-pressure water jetter is removed. Then, a winch or a team of men drag the liner through the pipe.
The LEDrig interchangeable head is then threaded through the pipe with the UV light activated after the liner is in place.
Specifically used when a damaged pipe has only one point of access. These can vary to, for example, a toilet or mainline, etc.
The QuickPatch LED will be inserted into the resin-filled lining where it is secured. The equipment is then lowered into the accessible manhole where it will line the pipe from the top to as far down as needed (at most 1000mm).
The UV light is then active for a curing time of 3-5 minutes.
