Welding Rig & Installation Tools

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 R&D redesigned and developed existing equipment to produce high-end tools, making the Sliplining process much easier and enabling it to be adopted for projects globally. These include the unique tools for the welding process:

• Welding Rig and Inserts
• Pipe Cutters
• Pulling Heads and Welding Balls
• Upper & Lower Pipe Guide

Already installed in over 16 countries since 2016, this innovative CIPP lining method uses DIBt certified Flexi-Pipe* which has 3 layers for flexibility. With 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

All of Picote’s new and redesigned tools make the installing process easier, faster and more efficient. The tools are simple, light-weight and have good ergonomics.

• The Picote Welding Rig revolutionises Sliplining. Only use what you need. Picote Flexi-Pipe can be cut to size and also comes in 6m (19.6ft) lengths which can be easily welded together using couplings. Easy to transport and store.
• The Pipe Cutter is used to trim the pipe to correct profile to commence welding.
• The Welding Ball is used to prevent the weld migrating to inside of pipe during the welding process.
• The Picote Upper Pipe Guide directs the flexible liner pipe from ground level to existing manhole chamber.
• The Picote Lower Pipe Guide changes the direction from down the manhole chamber through the invert and into the host pipe that is being sliplined.

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.
