Pipeline Integrity and Coated Steel

Abstract

Maintaining pipeline integrity is critical for continued safe operation of distribution and transmission systems in water, oil, gas and other sectors. Multiple choices of materials present a challenge for Corrosion Engineer and Integrity Managers. Pipeline Operators need information of the coating systems suitable for various environments and situations. Corrosion resistant organic coatings are the high performance materials that give long term protection to various atmospheres. Some such coatings now in use in industry need evaluation before recommending their use in industrial situation.

An attempt has been made to study steel samples coated with different coating materials, viz coal tar enamel, hot applied coal tar tape, high build epoxy, coal tar epoxy, polyurethanes & cold applied PE tape in tap and sea water environment to fed out their corrosion characteristics and suitability in specific environment.
