Pipe Relining: The Process in 8 Simple Steps
Pipe relining has exponentially eased the process of repairing and reinforcing an old and rundown pipe. Although it is not a foreign concept in British countries, it is fairly new to some which is why only those who are directly associated with the field knows how things really work. This new technology is not mechanism everyone has an understanding of. So, in this article, you will know the basics on how pipe relining works.
Step 1: Initial Pipe Inspection
Before any intrusive alterations are made, the first step is always to assess the condition or damage of the pipe. The technician or the plumber doing the relining uses a CCTV camera and snakes it into the pipe. This is an effective way to get live feeds from the camera while he remotely directs it into the different passages in the pipe that is to be fixed. This is a crucial step to know if the pipe can withstand being relined or if the interior is no longer fit but needs to be replaced altogether.
Step 2: Pipe Cleaning
This is where the initial inspection is getting useful. After diagnosing the situation inside the pipe, the technician or plumber decides the next course of action. Now, if the pipe is still in perfect condition for a relining, the next step is to clean and remove all obstructions inside.
The plumber usually uses high power water jets but when the obstructions are too big to be removed with the means, a robotic cutter is utilised. Robotic cutting tools are sharp enough to cut through metal and other hard materials that might be stuck inside your sewer pipe. When you are dealing with roots and other intrusions that cannot be removed using water, a robotic cutter is needed to get the job done.
Step 3: Post-cleaning Inspection
This step is to make sure that all the obstruction that were found inside the pipe during the first step is flushed out by the water jets or is cut and ground into pieces by the metal cutter.
Step 4: Pipe Liner Preparation
This step is for mixing the two-part epoxy liner that will be used to reinforce your pipelines. The mixture, materials, technique and epoxy type will depend on the need of your host pipe. There are certain epoxy mixes for different pipe needs.
Step 5: Pipe Liner Inserted
The mixture is then prepared for the lining. This process varies depending on the method you have chosen. You can opt for either CIPP, PIPP or other alternatives provided for your plumbing needs.
Step 6: Pipe Lining Cure Period
There are different methods to go about this process. Some curing process involves the need of heat or steam rollers that are inserted into the relined pipe while others need warm water to be injected into the pipe to speed up the curing process. It is important to follow the instructions and consumer manual in using resins and other relining products so you get the desired result. Do not attempt to tamper with the measurements or replace the designated curing agent with another product that advertises faster curing time. This may result to uneven lining curing and other may not cure at all and remain sticky.
Step 7: Post-lining Inspection
After the lining curing process, another inspection is done to make sure that the liner cured and is in its place, all holes and cracks are sealed and there are no defects in the lining.
Step 8: Pipe Relining Completed
After observing those steps carefully, you are done! After a few hours, your pipelines are ready to be utilised again. Congratulations and Happy Plumbing!
