Our high performance stand-alone ‘pull in’ liner for trenchless rehabilitation of pressurized water, gas, petrol, oil and heating mains.

SaniTube® is ideally suited for the trenchless rehabilitation of all common types of pipes – water, gas, petrol, oil and heating mains – including cast-iron, ductile iron, steel, PVC and asbestos-cement pipes from DN25 to DN400. Available with polyethylene (PE) and polyurethane (PU) coatings.


  • Minimisation of down times and traffic obstruction due to fast rehabilitation of long installation lengths of up to 700 meters including bends of up to 45°, depending on radius and diameter
  • Extremely cost efficient installation process
  • Low civil engineering works, reduced cleaning requirements for host pipe
  • Limited logistic costs
  • Low-cost installation equipment
  • Improved network efficiency through enhanced conductibility (e.g. K value)
  • Age tested to show no deterioration of over 50 years
  • 100% chemical-free installation process (no adhesives, resins such as epoxy, etc.)

SaniTube® consists of an extremely strong textile liner with an inner and outer PE coating. After cleaning the pipe, the liner is folded automatically, winched through the existing pipeline, inflated and pressurised to test. Afterwards is is reconnected to the existing systems using our SaniGrip PN16 couplings and recommissioned. Finally, the liner is expanded using compressed air and a final pressure test is conducted – thereafter the liner will remain completely stand-alone.

SaniTube® Installation & Engineering.

The ‘pull in’ procedure of SaniTube® requires a flange coupling connection. No resin, no impregnation, and no curing needed.

Setup & Installation.

SaniTube® is automatically folded, taped and winched along the cleaned pipeline. The liner is a flexible textile hose; delivered on reels, which provides a very long installation length of up to 1000m.

SaniTube® is then inflated, tested and Sanigrip® PN16 couplings are attached. These are then coupled on to standard pipe fittings and the pipeline is ready for recommissioning. Flange couplings are safe, easy to apply and suit all pipe materials.

Before conducting the pull in procedure, the pipe surface must be clear of obstacles, to prevent any damage of the tube.

SaniGrip® Flange Coupling.

SaniGrip® flange coupling PN16 is ideally suited for the reconnection of SaniTube® for all common types of pipes, including cast-iron, ductile iron, steel, PE concrete and PVC.
