The CP System is controlling ongoing corrosion of the embedded steel
Cathodic Protection Case Studies
Wellington Arch, London
ICCP - Steel Framed Monument
Rowan Technologies installed an ICCP system on the Grade 1 listed Wellington Arch in London in 2000. Due to previous water ingress, the key steel 'I' beams had suffered from significant corrosion. The steel 'I' beams had been physically displaced by up to 20mm in places, resulting in cracking of the historic stonework and jacking up of the quadriga.
Mixed metal oxide coated titanium ribbon and discrete anodes were used throughout the installation to facilitate a uniform current distribution. The ribbon anode provides maximum surface area ensuring efficient transfer of the corrosion inhibiting electrical current which is vital to sustain long term CP performance.
