Mô tả
this close-fit pipe lining system is ideal
for the renovation of structurally weakened
mains.
Our lining technology uses standard
PE pipe that is butt-fusion welded
into appropriate lengths, and pushed
through roller sets to reduce its diameter
concentrically by approximately 10%.
This reduced diameter pipe liner is stable
without the application of tension and can
be inserted into the host pipeline using
conventional sliplining techniques. Once
installed, the pipe is pressurised using cold
water to revert it back towards its original
diameter, retaining capacity and forming a
close-fit within the host pipe."
