This paper reviews the Polypropylene coating materials and systems available for high temperature applications, (up to +140°C for thermal insulation subsea and currently 110°C onshore). A number of interesting case studies are presented and papers are reviewed on coating failures. It also examines the selection of fusion bonded epoxy and field joint solutions with their advantages and disadvantages. Some available data, possible requirements and test regimes that could enable qualification of Polypropylene materials for temperatures above 110°C onshore are reviewed and discussed.
