The right coatings system correctly applied on structural steel and tankage in process plants can confidently be expected to give good corrosion protection for periods between 10 and 20 years. However on hot areas both atmospheric, with temperatures up to 500°C, and protection under insulation for high temperature pipes and vessels this is often not the case. Many coatings used in these areas are too intolerant for site application and general use in this industry, leading to expensive premature failure.

This paper describes development of new products in these areas and also the difficulties encountered in the development of a non zinc high temperature coating for use up to 400°C. An alternative approach to thermal insulation with in-built corrosion and damage resistance is also covered. The development of internal test methods necessary to undertake this work is also described.
