    Preparing Pipes for Coating -

    Let's Check First ...

    You never know, until you check.

    Comparing the data collected on site against those delivered on paper maps and lists is essential for a successful project. Diameter changes, unknown bends and deviating lengths, intruding objects and other surprises need to be identified before going into a pipe with any equipment.

    Safety and handling instructions made the contractor's team feel confident handling the Miller, pump and tools which significantly reduces the risk of equipment damage and injuries.

     

    Preparing pipes for Picote Brush Coating™️

    High-Speed Cleaning 

    Initial CCTV results showed deposits and encrustation in the DN100 cast stack pipe and the DN100 PVC toilet drains which needed to be removed before coating. Picote's Senior Technical Trainer, Jukka decided to use the following tools:

    • Tiger Original Chains DN100
    • PVC Original Chains DN100
    • Picote Smart Cutter™️ DN100

    Tiger Chains were first used to remove the main deposits and encrustations from the inner stack pipe wall (19m length).  Original Chains DN100 for PVC pipes prepared the toilet drains for coating without risk of damaging the pipe inner surface.

    The Picote Smart Cutter™️

    To finish the pipe preparation, the Picote Smart Cutter™️ equipped with Side Grinding Panels 50x100 ensured a smooth finish providing a well bonding surface for the first coating layer.

    To remove fine dust or other loose particles the pipes were briefly cleaned with a soft Picote Cleaning Brush 125mm for DN100 - 8mm Shaft.

    Picote Brush Coating™️ Procedure

    After completing the cleaning work in the early afternoon of day two of the project the coating procedure was started in a service room on the hotel's top floor with access to the upper end of the 19m stack pipe.

    Setup of all required components ensured a smooth operation and quick  transport of equipment from one floor to the next when the toilet drains were ready to be coated.

    • Mini Miller
    • Mini Pump
    • Smart Mixer
    • Picote Dual Colour 100% Epoxy Cartridges
    • Coating Brushes & Tools
    • CCTV Camera

    The Mini Coating Pump combined with a Picote Mini Miller delivers the 100% Solids Epoxy Resin mixed with a Smart Mixer from pre-packed handy cartridges, providing an easy and mess-free solution. The use of dual colours (white & grey) improves quality control with visual verification between layers.

    In the afternoon of day two, one layer was applied on the stack pipe giving the team a feel of how to handle the brushes, the pump and how they should monitor the whole process with a camera attached behind the coating brush.

     Over the next two days, a total of three coats were applied to both the stack pipe and six toilet drains.

    Project Assessment

    Continuous camera monitoring of the entire coating process showed that the slick new inner surface increased the flow inside the pipe. This also minimised the risk of blockages and formed a seamless new semi-structural pipe, providing a solution for several more decades.

    The pilot project delivered very promising results in only four days for only 60% of the costs of using traditional methods. Most importantly for the hotel, normal daily services for customers were not disrupted or affected by the renovation works.
