The 5 Steps in Relining Pipes with Cured-in-Place Pipe (CIPP)

Pipe relining continues to become one of the primary solutions used in pipe repair since it can be done quickly and improves the inner lining of the sewer system. It’s no exaggeration that pipe relining can be finished promptly, since there are small to medium pipe repairs that were done in just a few hours while the bigger projects took a few days. Now if you contrast this with replacing pipes it’s definitely faster since pipe replacement can go on for weeks while creating insane destruction to properties. So how does pipe relining work and why can it be done at such haste? This article will show you the steps in pipe relining.

Pre-Check up

Before a pipe relining is done, the plumbing company or contractor must first assess the sewer pipes if rehabilitating will actually be a viable solution. You see, even if pipe relining is a remarkable solution for damaged pipes, it has its limits. There are situations in which the pipes have taken so much deterioration from age or usage that it’s futile for the pipes to be relined. Aside from that case, a collapsed pipe also calls for a pipe replacement. This doesn’t mean that homeowners will have to resort back to old and inefficient methods since there are trenchless pipe replacement technologies available. If your pipes are suitable for relining then the contractor will schedule a date and setup the required tools and supplies as well as secure necessary permits.

1st Step

Even if the pipes just need a bit of help from enhancement, it must still be cleared from any form of blockage like roots, mud, oils, grease, etc. Any form of obstruction can be accurately located with the help of a camera. Once the threats against the operation have been identified and sighted then the clean-up will start. It’s important for the pipes to have smooth and clean lining so that the resin which will be used later on will have no trouble bonding with the host pipe. Plumbers usually use either hydro jets that bursts high water pressure or a cable machine.

2nd Step

Another camera inspection is conducted to get the accurate measurements of the pipe like the diameter, radius length, etc. After the measurement has been taken, the contractors will start creating the liner that has the adequate size and volume to be able to insert it into the pipeline.

3rd Step

Once the liner is completed, it is then placed together with a packer (also known as a bladder) and then placed into the sewer system .The packer has two purposes which is to help allocate the position of the liner and being inflated in order the resin liner to bond with the old pipe. After the resin liner has bonded, the packer is then removed.

4th Step

The next step would be the curing process. The resin can actually be left alone in order to be hardened but this will take a lot of time. For the curing part to be done faster, hot steam or warm water is applied into the lining. The hot temperature will cause the liner to solidify at a faster rate.

5th Step

The final step is to check if there are no issues with the liner. Basically, it’s just another camera inspection to see if the output is properly done.
