Fusion bonded epoxy (FBE) coatings have been used on pipelines as protection against corrosion for over 40 years. They have been used as a stand-alone product in single layer systems and as a primer in dual and three layer systems. To achieve optimal performance, current FBE products require application temperatures in excess of 230°C for single layer systems and 200°C for three layer systems. The introduction of high strength steels such as X80, X100 and X120 for use in pipeline construction has presented a challenge to the industry in terms of the availability of suitable coating systems. High strength steels (particularly grades X100 and greater) cannot withstand pre-heat temperatures in excess of 200°C. Exposure to the high heat required when coating with a typical FBE product results in the degradation of some of the key properties of these high strength steels.

This paper will discuss the development and performance of a new generation FBE coating that can be applied at temperatures as low as 180°C for single layer systems and as low as 150°C for multi-layer systems. Performance of this new product will be compared to one of the best performing commercially available FBE products applied at 240°C.

Key Words: fusion-bonded epoxy, FBE, pipecoating, low temperature application, low temperature cure, high strength steel, cathodic disbondment

In this paper, failure analysis methodology will be applied to the principal mechanisms by which FBE coatings fail during long term service; with specific application to case studies involving blistering. The case studies apply standard failure analysis techniques to determine the primary causes and modes of failures.
