Product Details
UV liner for the trenchless repair of underground and municipal
sewers pipelines
Method for preparation of UV CIPP process
Use a CCTV robot to thread a rope to pull the bottom membrane: (use
a braided rope, do not replace the rope at will, otherwise, the
material or membrane will rotate in the pipe) the connection buckle
between the rope head and the bottom membrane should be firmly
fastened, and another rope to pull the material should be placed on
the upper end of the bottom membrane (if a winch is used, it is a
steel wire rope).
Ensure that the material and rope are not mixed with the rotation
of the bottom membrane during the membrane pulling process. For
long-distance materials with large pipe diameters, soapy water can
be added to the bottom film to reduce the friction when the
material is dragged.
