The pipe lining and curing process begins with the pipeline bypassed and the upstream manhole plugged. The pipe is then cleaned and a robotic camera is run through the pipe taking video footage of the entire length noting any issues that may need to be addressed before the lining is installed. A rope is pulled into the pipe during the video process with the camera itself. After the pipe is prepped and videoed, a pre-liner and a second rope are pulled through.
The cable on the winch at the downstream manhole is then attached to the rope and pulled back through the pipe. The StreamLiner UV™ is then attached to the winch cable and pulled through the pipe with the winch. Safety sleeves are placed on the liner at both ends to insure the end caps are secure. The end “gates” are then placed on each side of the liner in order to inflate it to 8psi.
The StreamLiner UV™ Light Train is then inserted through one end and pressure is restored. The Light Train camera is activated and the train is manually pulled through the liner in order to visually inspect it for any potential problems.
After the liner inspection is complete, the Light Train is once again pulled through the liner, this time via computer. The computer controls the speed, temperature and pressure of the process which are all carefully monitored via laptop computer during the curing of the pipe liner.
When the CIPP process is complete, the ends of the liner are trimmed, a cutter is inserted and precision cuts are made at each lateral to restore service to the main. The StreamLiner UV™ Light Train system cures at speeds in the 4 to 8 foot per minute range. A length of 300 feet of 8 inch UV CIPP liner can be cured in 50 minutes.
LightStream, LP’s fiberglass cured in place lining system takes one third the set up time of felt CIPP and breaks down in minutes, not hours. It is the most efficient, high technology CIPP system available in the world.
