Brief Explanation of the Pipe Relining Process
Pipe relining or also known as cured-in-place pipe repair is one of the solutions under the revolutionary pipe rehabilitation restorations. It isn’t really a surprise why pipe relining has become such a favoured pipe repair method since it doesn’t cause any sizable damage during repairs and can be finished in just a few hours or a day, depending on the project. Below is a brief yet detailed explanation of the pipe relining process.
1. Pipe assessment
Before the relining process even begins, the pipe repair services must first assess the extent of the damage of the pipeline and if relining is indeed the best solution. Despite pipe relining being a superb pipe repair method, it isn’t the answer to all sewer pipe problems. There are circumstances in which a pipe replacement is the more appropriate fix. Contractors use a drain camera to check the status of the pipeline. Aside from checking the damage, they will also look out for obstructions and clogs that can affect the whole process.
2. Cleansing the pipes
In pipe relining, the host or damaged pipe must be free from any blockage to ensure that the resin liner will bond with no issues. Therefore, cleansing the pipes from clogs and other obstructions is top priority. One of the most popular equipment used for removing intrusions in the pipeline is with the use of robotic cutters. However, these cutters are better suited in removing tree roots that are often found in damaged sewer pipes. Another tool in cleansing pipes is the water jetter. This jet is capable of releasing high water pressure in order to clear off both solid and liquid clogs.
3. Another pipe assessment
The drain camera is once again sent down to the pipeline to make sure that there are no more obstructions in the pipeline. Measurements for the lining are also checked.
4. Creating the pipe lining
Once there is enough accurate data of the measurements, the creation of the liner will then start. Epoxy resin is usually applied to the liner, which will then serve as the new pipe.
5. Plugging the epoxy resin liner
In this step, the liner is then inserted to the sewer system with the use of an inversion drum. Take note that this is for inversion pipe relining. If the epoxy resin liner is finally inside the sewer pipeline, it is then pressed to the lining of the host or damaged pipe with the use of either water or air inversion.
6. Curing the liner
By this time, the pipe repair services can just wait for the resin liner to harden, but this will actually take a long time. They can accelerate the hardening process by curing the liner with the use of hot steam or water.
7. Final check-up
A final check-up is done by sending the drain camera again and visually checking the resin liner. They will also use leak detection tools to ensure that there are no present leaks with the sewer pipeline.
