The Process of Cured-In-Place Pipe (CIPP) Lining made easy
What is Cured-In-Place Pipe (CIPP) lining all about?
CIPP is just one of the few applications that belong to trenchless pipe rehabilitation. Like most of its pipe lining counterparts, the whole CIPP process revolves around bonding a resin liner into the old or host pipes so that it will be able to reinforce the structure of the sewer pipeline. It has become a famous procedure in pipe repair and continues to do so.
How is the process done?
Plumbers and pipe repair contractors must first gain insight of the condition of your sewer pipes. You see, CIPP and other pipe relining methods may be more convenient, less hassle, and more economical in the long run, but it’s not all the time that these pipe repair applications are suitable. After assessing the pipe’s condition, they will be able to notify the property owner if CIPP should be done or not. In case the pipe repair team will go with pipe relining then they will most likely use the following steps below.
1. Getting rid of the obstructions inside the sewer line
It’s definite that sewer pipes that need any form of pipe repair will have clogs and obstructions in its sewer system, which is why clearing the pipeline is the initial step in CIPP. The obstructions found will vary from roots, soil, mud, oils, grease, and even the crumbling structure of the pipes. There are many tools that can be used to get rid of these blockages such as hydro jets, mechanical cutting tools, augers, and so much more. However, the tools used will depend on the situation. For example: using a powerful water pressure from a hydro jet is not recommended for a fragile pipeline since it will make the pipes more damaged and possibly collapse the pipe lining.
Now that the obstructions are gone, the contractors will now be able to accurately measure the pipeline. Measuring the length and diameter of the pipes since the contractors will model the new pipe liner according to said measurements. They will be able to create a liner that will fit perfectly into the sewer line. During this process, the resin is also mixed with the liner. This resin liner will serve as the new and core pipe of the system.
3. Introducing the resin liner
The resin liner is placed into a bladder before it’s placed inside the sewer system. This bladder is an important tool since it can help in positioning the liner. Once it’s in place, this bladder will then be inflated to allow the resin liner to bond itself together with the old & damaged pipe. The resin liner will then be left to be cured (basically hardened) for a few hours, depending on how much of the pipe system needs to be repaired.
4. Final inspection
If the pipes are finally cured, the bladder is then removed and a final inspection is preceded. The examination of the newly cured pipes is also an important step since it will be able to certify that the curing process and positioning of the liner was perfectly executed. Of course, if there are any errors, then certain adjustments need to be done.
