Description
Picote Flexi-Sliplining offers emission-free manhole to manhole trenchless rehabilitation for gravity pipes from DN100-300 / 4-12″ using unique three-layered corrugated DIBt certified PE pipe.
Picote Flexi-Pipe* is a 3-layer corrugated outer layer/smooth inner layer PE pipe which provides excellent flexibility when used as a sliplining product. Installed manhole to manhole as part of the Picote Sliplining method. DiBt certified (*tested under name of Flexirohr). HPWJ tested to 180 bar by WRc in accordance with WIS 4-35-01 2008 appendix B.
Already installed in over 16 countries since 2016, this innovative CIPP lining method requires minimal training and only needing a two-man operation, this easy manhole to manhole installation, requires no excavation and does not require bypass pumping. A cost effective solution, Picote has designed welding and installation equipment to compliment this application process.
USES AND BENEFITS
There are many benefits to using Picote Flexi- Pipe as part of the Picote Slipining method:
- For DN100-300 (4-12″) pipes.
- Stand-alone pipe SN4 or SN8 = new pipe for 50+ years!
- DIBt certified tri-wall pipe, more flexible than traditional PE pipe.
- Manhole to manhole installation.
- No emissions during or after installation.
- Low raw material usage = less CO2 emissions.
- Fast & economic installation – 8m (26ft) per minute.
- Can negotiate bends.
- Easy to transport, store & handle.
APPLICATIONS
There are many considerations when choosing Picote Flexi-Sliplining for your gravity sewer project. It is especially applicable in situations where it is not possible to CIPP line the pipe or where there are environmental concerns or potential high risks.
The ring stiffness class of the pipe is SN8 (DN 270 Flexi-Pipe is SN4). Whilst an ideal solution for main line sewers, in the diameter range, the system is also particularly applicable to the rehabilitation of house connections.
Picote Flexi-Sliplining can be used in cases of:
- Infiltration: No bypass pumping needed.
- Tidal Areas: A fast solution – pull in at rates of 8m per minute.
- Deformed Pipe: Install a smaller diameter without sacrificing flow rate.
- HPWJ: Passed WRc testing to 180 bar according to WIS 4-35-01 2008 appendix B.
- Increase Flow: Improve flow in cast iron, clay and concrete host pipes.
- Factories and Processing Plants: great chemical resistance.
- Laterals: Reinstate lateral connections with Picote Connection Collar System.
- Standalone Pip: Stronger than CIPP Lining. Ringstiffness (kN/m2): SN8
As with all sliplining systems there is a slight loss of inner diameter once the installation is completed, which does not affect flow. Also suitable for house connections.
