In November 2007 Techcoat Services Insitu Electroless Nickel Plated (EN) a 12 meter long 1.5 meter diameter, high temperature, high pressure, caustic reaction vessel. At the time the vessel was corroding at around 3,000um per year (of carbon steel), being replaced every 3 years and was then 2 1/2 years into it’s life – it had around 6 months of corrosion allowance remaining before it would be condemned.

In July 2011 (after over 3 1/2  years) the vessel continues to be in use with the EN plating effectively halting the underlying carbon steel corrosion. That’s more than an extra 3  years life on top of the 6 months anticipated.
