Integrated CIPP UV repair equipment for private households and
public pipelines
Pulling CIPP UV liner into the pipeline
1. Place the hoist on the wellhead to align the reel with the guide
wheel, and the personnel at both ends can start the hoist to pull
materials when they are ready.
2. During material delivery, ensure that the materials are folded
neatly and are not scratched by foreign matters during material
movement, especially at the wellhead and nozzle. (you can brush
lubricant under the material to reduce the resistance of pulling
the material).
3. The pulling speed shall be controlled within 5m/min.
4. If space permits, try to leave a certain distance between the
steelhead and the pipe orifice to ensure that the finished incision
is beautiful. When the material is approaching the end, do not pull
too much, otherwise, it is very troublesome to pull the material
backward. The hoist can be stopped when the material is pulled down
to a proper position.
5. Remove the rope for pulling materials, rope tightener, lifting
belt, universal shaft, and guide wheel, and put them back in the
original place for next use. (when pulling the material, it is
better to keep the material tight and observe whether the bottom
film is pulled).
6. Repair the pipes of DN600 and below. The length of the two ends
of the inner liner extending out of the original pipe is about ≥
600mm. Repair the pipes of DN600 and above. The length of the two
ends of the inner liner extending out of the original pipe is about
≥ 1000mm.
It depends on the site conditions.
