The Cured in Place Pipe (CIPP) process is simplified and summarized in the diagram to the left.
The section of pipe to be rehabbed is first isolated from flow.
The proprietary materials are placed inside the pipe.
The CIPP operators will then work their “magic” through various pieces of equipment to cure the liner to the pipe, creating a tight seal that also acts as a structural base.
The CIPP equipment is removed and the individual service taps are reinstated using a robotic cutting tool. When all service lines are opened up, the section of pipe is placed back into service.
Depending on the length of pipe, each section normally takes approximately 3-4 hours from start to finish.

After the pipe section has been closed off, cleaned and TV-inspected, rehabilitation work can begin and the flow of traffic can continue
9:00
The sliding film is drawn in – at the same time the packing will be installed at the ends of the liner.
9:30
The liner will be drawn into the existing pipe, then inflated using compressed air.

Curing of the installed liner under UV light or steam heat.

The entire computer controlled curing process is supervised and the rebabbed construction area can be put back into operation on the same day. (Cross section of lined pipe below).
