Project Details
Engineers at Korea National Oil Co. decided they needed to protect the flanges on underground pipework from corrosion; with this in mind, they asked K-Cotech Co. Ltd for a long-term and cost-effective corrosion prevention solution.
K-Cotech recommended a system from Winn & Coales (Denso) Ltd.
After surface preparation of the areas to be protected, a petrolatum primer was applied (Denso Paste™), followed by Densyl™ Mastic which was applied to awkward shapes and to fill voids, in order to create a smooth profile for tape wrapping. Densyl KF™ Tape was then applied, followed by an outer wrap of Densoclad 40HT™ to complete the system.
Application was completed with this working procedure, and all KNOC engineers were very satisfied with great result.
