7.5m (24 ft) for a DN50 (2 in) diameter liner.
Different inversion heads in the three diameters are available for each Cannon model and the Fast Cap Lock element is a one-size-fits-all item.
HOW THE CANNON WORKS Both the Original Cannon and Cannon Mini operate in the same way and utilise ambient cure lining techniques. Using the Picote Fast Cap system to seal off the ends of an inserted liner, the Cannon unit can be used on multiple installations without having to wait for a previous liner to cure. Picote Curing Caps (sold separately) can also be used.
Both Cannon models work with compressed air to a maximum operation pressure of 2 bar (29 psi). If a CCTV camera is required to be used during the installation this needs to be installed through the compressed air inlet prior to the loading of the liner into the Cannon (full installation instructions come with the product literature).
For lining, first the correct inversion head is selected to match the diameter of the liner being used. The Quick Cap will also need to be ready and waiting to seal the liner after installation.
The pipe to be rehabilitated should already have been cleaned and inspected and the length of the liner required ascertained. The evenly resin impregnated liner of the correct length is then packed into the Cannon according to the manufacturer’s instructions and the Cannon connected to the compressed air supply. The hand-held Cannon is then positioned at the launch end of the host pipe and pressurised inverting the liner into it. The Cannon pressure-relief systems will not allow over pressuring of the tool or the liner during the installation operation. The flow of compressed air is regulated to ensure that
the liner is inserted at the correct speed allowing it to form the best fit lining within the pipe.
Once the liner insertion is complete the Quick Lock Cap ensures the liner remains pressurised and inflated until the cure process is completed and the Cannon can be removed for the next liner installation.
Picote also offers the Sentinel System which can be connected to the curing liner/pipe which can be used to monitor the pressure of the compressor and electricity power network. It will alert the operator, via text message, if air pressure at the compressor or power to the compressor is lost, allowing the crew members to react accordingly to avoid a failed liner.
Commenting on the Picote Cannon, Katja Lindy- Wilkinson, CEO of Picote Solutions said: “The advantages of the smaller, lightweight, compact and easy-to-use hand-held Cannon are being experienced internationally. The potential for this application globally has to be immense given the general move towards trenchless rehabilitation of pipe inside buildings that we are beginning to see instead of ripping pipes out and replacing them. We are very excited about offering more innovative tools to CIPP contractors as our industry keeps developing and growing.”
