Recent development of new oil and gas producing areas in Canada created a demand for pipelines operating at elevated temperatures.

A new three-layer epoxy/polyethylene coating was developed to answer a growing need of the Canadian pipeline industry for high temperature resistant coatings. An industrial research program was undertaken to select the most suitable materials and to determine the highest operating temperature of this type of coating, as well as to define properties of this type of coating at elevated temperatures.

This paper describes the work performed at Pipe Coating Systems to better understand the physical, chemical and mechanical properties of this type of coating.
