The winch-in-place method is also called WIP. The method involves pulling the liner into place in the tube using a rope or wire. Inpipe has further developed other suppliers’ WIP method so that you can inflate the liner and insert the UV light train directly from the vehicle. You do not have to release the air pressure and climb down into the well. This way, the risk of severe damage to the liner is minimized. The installer does not have to expose him/herself to dangers by fussing with a UV light train deep down in a narrow well.
Winch-in-Place from the installation vehicle
When retracting with Inpipe’s equipment, you can often pull the liner into your pipe directly from the vehicle, depending on the situation and dimension of the liner. You can then connect a bend, set the air pressure, and expand the liner. When it is ready, pull your light train into the liner, directly from the vehicle, without releasing the air pressure. Safe, easy, and flexible!
The entire installation process takes place while maintaining air pressure to ensure the best fit and reduce the risk of errors and problems. The technology creates a very tight fit between the liner and the existing pipe. Any water that remains in depressions in the pipe is pushed away during installation. This helps to ensure that the shape of the pipe does not risk changing and you keep the cross-sectional area of the pipe. The gap between the existing pipe and the liner will be minimal, less than 0.1% of the diameter.
The method requires custom equipment provided by Inpipe.
