Pipe lining also known as cured-in-place pipe (CIPP) lining is a non-destructive solution that’s not just a temporary plumbing fix. There are several pipe lining installation technologies in the industry however, the best pipe lining product will create a structural epoxy pipe that adheres to the inside of the damaged pipe. Why spend money on pipe lining your pipes? Whether it may be a cracked drain line or root infiltration or corrosion buildup restricting the diameter of your pipes – CIPP lining can offer a cost effective and efficient solution in comparison to conventionally re-piping. Snaking or jetting a sewer line is only a temporary fix – CIPP lining is a long term solution.
What Is The CIPP Lining Process?
- A typical pipe lining project begins with mapping the internal plumbing system by CCTV camera inspection. A plan is implemented to minimize disruption and afford the most efficient timeline for work completion.
- The cleaning process involves removing roots and debris buildup in order to return the pipe to its original functioning diameter. Removal methods may vary depending on the condition of the pipe.
- Existing access points are used to push or pull an epoxy-saturated felt liner into the damaged host pipe. This lining method provides the ability to line multiple 45 and 90 degree angles, as well as the option of lining specific sections of pipe without lining the entire length.
- Once completed, a final CCTV camera inspection is performed. A smooth, joint less epoxy pipe now is covering the existing host pipe.
What Is Pipe Coating?
Epoxy coating a pressurized pipe system such as potable lines, HVAC systems and fire suppression lines is a completely separate technology and installation process versus CIPP lining.
What Is The Pipe Coating Process?
- An effective epoxy coating process begins with walk through to determine the problem areas and pipe configuration. A plan is implemented to minimize disruption and afford the most efficient timeline for work completion. The piping system is also inspected for integrity and spot repairs from excessively worn joints and fittings. A temporary bypass water pipe may be installed.
- After testing for leaks, the pipes are prepared for cleaning. Compressed air and a safe abrading agent is blown throughout the pipe system, removing rust and corrosion by-products that are collected in a hold unit for disposal. Compressed air is applied once again to remove fine particles.
- The epoxy coating is applied to the pipes using conditioned air to uniformly distribute the epoxy throughout the pipe segment. Following the coating application, continuous controlled air flows through the pipes during the epoxy curing process.
- When the epoxy cures, valves and couplings are refitted and a final leak test confirms the integrity of the line. In addition, water quality, volume and flow tests confirm the functionality of the system.
Pipe lining and epoxy coating provides a non-disruptive, time efficient and cost effective solution in comparison to traditional pipe replacement. Used for both non-pressurized pipes such as sewer and vent stacks and pressurized pipe systems such as potable and fire suppression, pipe lining and epoxy coating is not just a band aid fix but a long term solution.
