CLOSE-FIT

THE PRE-DEFORMED PE PIPE FOR CLOSE FIT LINING

For more than 25 years the r.tec® Close-Fit technology (Fold-and-Form method) has been used successfully for water pipes.  In close cooperation with leading producers of plastic pipes, NordiTube has steadily enhanced and optimized this system.

This fold-and-form method is used for the rehabilitation of potable water, gas, gravity and industrial pipes.
