Pipe repair has never been a fun process. Digging up your pipes and meticulously repairing or replacing damaged ones is slow and laborious work.
This is where the cured-in-place pipe comes in. It’s a much easier and cheaper method for repairing existing lines. It can also help to extend the overall lifespan of your pipes.
Also known as CIPP, this method is especially popular for large, underground pipes that are expensive and difficult to access.
How does CIPP work? What different cure systems are out there, and what are their strengths and weaknesses? Let’s take a look.
Cured in place pipe is a type of pipe rehabilitation. It’s designed as an easier way to repair existing pipelines and is especially popular for underground pipe repair.
The process begins by mixing a liner and a resin together. The resin is a mixture of epoxy and some kind of hardener. These will form the liner that is used to repair the pipe.
An air pressure machine is used to invert the liner into the pipe that is being repaired. After this, the liner is cured using one of a few different techniques. The curing process hardens the liner, which completes the process.
There are three main curing systems that are used during the final step of the process. These are hot water, steam, and UV curing.
Hot water curing was the first system created for CIPP. It’s also the most difficult system. In this process, you use cold water to expand the liner. Then, using a boiler, you use hot water to solidify it. Finally, another round of cold water is used to cool the liner.
This system is difficult, clunky, and inefficient. It requires a large amount of space for all the equipment required.
Steam curing is a step up, mostly because it’s a faster process than hot water curing. However, it still requires a lot of equipment and space.
The best option is self-curing epoxy. The liner is soaked in epoxy and is inflated inside the pipe using compressed air. The epoxy cures on its own, meaning there’s no need for clunky, expensive equipment.
There are some limitations to CIPP, of course. It will only cover a portion of the pipe, for example. This can leave the rest of the pipe exposed to future damage.
Still, CIPP is a marked improvement over dig and replace pipe repairs.
Cured-in-place pipe is a great way to rehabilitate old, damaged pipe systems. It’s a cheaper, quicker, and more efficient way to repair your existing pipelines.
So the next time you have a pipeline in need of repair, call a CIPP specialist and get your pipes repaired quickly and easily.
