Denso P1 System protection selected for Kempton Park Water Treatment Works

Denso’s P1 System™ for the protection of ferrous pipes, joints and fittings was recently utilised by Morrison Water Services on behalf of Thames Water at Kempton Park Water Treatment Works.

The work involved protecting 32 flanges, joints, and 4 x 1000 mm valves with the system, which is fully compliant with P1 Civil Engineering Specifications for the Water Industry (7th Edition).

The system consists of a primer (Denso Paste™); mastic (Denso™ Profiling Mastic), to fill any voids and create a smooth profile; and petrolatum tape (Denso Tape™), wrapped with a 55% overlap. When administered correctly, the system offers long-term, effective protection from corrosion and can be applied on site before assets are buried.
