Our Czech partners, Corrotech, recently provided corrosion protection of the internal parts of two 2 x 12m2 fire foam tanks, for a client in the Energy Industry at a Nuclear Power Plant.
The tanks stored a fire foam concentrate which had caused damage to the existing internal linin, resulting in pitting corrosion. The Corrotech team carried out the work in-situ at the Nuclear Power Station and began by removing all of the existing deposits and paint before decontaminating the surface from soluble metallic salts.
Following abrasive blasting, the team discovered a number of sharp edges and bad quality welds which needed to be mechanically adjusted ahead of the coating system being applied.
The coating selected for this job was Corrocoat Zip E, an epoxy glassflake coating offering durable protection in aggressive atmospheric conditions – ideal for the long term protection of internal substrates of these fire foam tanks.
