In using Cured-in-Place Pipe (CIPP) as a pipe repair method, one of its crucial steps is the curing or basically the solidifying of the liner placed into the pipes. Popular ways to cure the liner is with the use of steam or hot water. These methods are indeed effective, but there is another technique in which a UV light-cured liner is applied to the sewer line. Using UV liners have its advantages in the CIPP rehabilitation, check them out below.
Its material composition is impressive
The material used for the liner in the CIPP process is mainly epoxy. Using epoxy is commendable since it’s easy to add into an aged or damaged sewer pipeline. It also has other benefits apart from the one mentioned like; stable and strong material, impervious to leaks, not prone to root takeovers, and can’t rust. In using a UV liner, the material used is fibreglass. This component is just tough as epoxy but it has a lower resin usage which makes it more economical. Once this UV liner is inflated, it increases its diameter and becomes more effective in curing the affected pipe.
Forms as a tough fortification
Some pipe relining contractors make use of polymeric films on their UV liner to make a tougher fortification of the pipe lining. This film helps envelop the resin and improve its structural integrity. With the enhanced fortification, the liner can withstand and can even adapt to the water and waste of the sewer systems.
One of the innovative methods of resin thickening allows the UV liner to be spread out evenly. This allows the thickness of the liner to be consistent and free from errors. Because of the consistent liner dispersion, the water flow of the pipe system is vastly improved.
Uses less energy in curing
Curing a liner with the use of hot water and/or steam can consume a lot of energy and also needs to be cooled through refrigeration. It’s also beneficial to the environment since it doesn’t use too much water in the curing process. Some of you may be wondering why it needs to be refrigerated. You see, the curing immediately starts once the liner is exposed to heat. So in order to stop the liner from curing even if it’s not inserted into the pipe yet, it must be stored at cool temperatures. The UV liner doesn’t need to be cooled thanks to its fibreglass composition and film cover.
CIPP can be used on tough projects like putting the liner into uneven pipes. UV liners have the same adaptability when it comes to inserting into the pipeline as it can be easily integrated into the system. In fact, CIPP can be implemented into other construction work involving more than just sewer pipelines.
A recurring issue when it comes to traditional pipe repairs is that there should be a total closure in the area due to environmental hazards, and even water contamination. CIPP UV lining doesn’t have these issues since the liner is just placed into an entry point and has no effect on the groundwater, eliminating the threat of contamination.
