Cured-in-place pipe repair (CIPP) is a trenchless method of restoring damaged pipelines. This method of pipe repair has restored sewage pipes since 1971. Now, experts around the globe use CIPP as an alternative to traditional pipe restoration.
Read on to learn more about cured-in-place pipe repair (CIPP), how it works, and why it lasts longer than traditional pipeline repair.
How Does CIPP Work?
CIPP maintenance uses resin to form a new layer over the damaged pipe. To restore the line, specialists use textile liners and liquid resin. The liners are made with a resin combination that consists of an epoxy base and hardeners.
The experts push the textile liner into the pipe with air pressure. At this point, the resin is on the exterior of the damaged pipe. Then, the calibrated tubes are inserted into the textile liners and cured with steam or hot water.
The curing substance activates the resin, causing it to harden and form a smooth, corrosion-resistant pipe. Often, professionals restore lines with diameters of 3 to 98 inches in as little as one day.
How Long Does CIPP Take to Dry?
The CIPP drying process can take anywhere from one hour to thirty hours. The drying time depends on several factors:
Degree of Damage
In CIPP, the number of liners you need depends on the type and degree of damage. You’ll need one liner for each pipe, but if several lines are damaged, the overall drying time is longer.Â
Pipe Diameter
The diameter of the damaged pipe can affect a pipe’s drying time. Smaller lines often dry in less time than larger pipes.Â
Pipe repair specialists perform CIPP on almost all pipes, including storm drains, sewer pipes, and water lines. These pipes come in varying sizes, so they will have different drying times.
Drying Method
The drying time directly depends on the drying method. Sometimes liners can air-dry, but this process takes the longest time to set. Air-drying a CIPP liner can take up to thirty hours.
A quicker method involves using ultraviolet light (UV) to heat the pipe. Under the action of UV light, the resin solidifies faster than conventional curing methods.
Why Does CIPP Last Longer?
CIPP lasts longer than traditional repair because it can be redone seamlessly. Old-fashioned pipe repair involves digging a trench and replacing the entire line.
A CIPP pipe may have several epoxy layers applied to it over time, increasing the life of a pipe system to nearly a century. A pipe system is the complete interconnection of pipes, including pipe fittings, flanges, pumps, valves, and tanks.
Cured-in-place pipe repair is a much faster alternative to traditional restoration methods. It saves professionals time and resources from digging trenches.Â
