AMPP describes itself as the largest global community for corrosion and coatings expertise, safeguarding assets through education, credentialing, accreditation, innovation and standardization, and its certification programs cover coating inspection alongside cathodic protection, protective coatings and corrosion prevention. The AMPP CCI-1 case studies are 5 cases and about 2,921 words.
1Salt Contamination on a Bridge Recoat Over Solvent-Borne Inorganic Zinc
A 1970s steel girder bridge is being recoated. The existing system is a solvent-borne inorganic zinc primer that is largely intact on the webs but has 15-20% rust-through on the bottom flanges and around rivets.

A field-applied fusion-bonded-epoxy-equivalent liquid pipeline coating (two-component epoxy, 12-18 mils DFT) is being applied to 24-inch pipe in a laydown yard. The applicator sprays, and the inspector checks wet film thickness (WFT) with a comb gauge, reading 14-16 mils on the top of the pipe and 8-10 mils on the bottom.
