Is it a new technology?
The CIPP methodology, was created in 1971 by engineer Eric Wood from the United Kingdom then a trial phase, in the year 1977 this methodology of trenchless rehabilitation, was introduced in the United States and was widely accepted worldwide.
Does it work for potable water piping?
Yes, this piping rehabilitation method is used for sewage and also for raw or potable water piping with or without pressure.
What about the flow and that rehabilitated pipe connections?
They diameter decrease obviously decreases the transporting section but a smoother lower new surface translates into lower pressure drops, this is why the difference in loads is not significant the flowtate might even be higher after rehabilitation.
As for the connections, these can be reconstructed by robots with special tools from inside the pipe itself.
Can a pipe with infiltrations be rehabilitated?
Of course. Is only needed to bring down the water flow level and/or stop the infiltrations to be able to implemented rehabilitation methodology, preliner on the sleeves can be used when stopping the dripping is impossible.
How long does the curing cycle take?
It depends on the curing method, (vapor, hot-water, ultraviolet light), the diameter of the pipe, the curing time could vary between 5 to 30 hours.
