Main Objective
The aim of the proposed work is to improve the performance of multi-layer coatings through an understanding of the factors that affect the level of residual stress in the coating and the consequences for coating disbondment. This improved understanding is expected to (1) lead to the identification of improved methodologies for surface preparation and coating application, (2) enable the evaluation of construction or in-service damage on the long-term integrity of the pipeline and, consequently, (3) result in a greater acceptance by the North American pipeline industry for the use of these inherently safer, advanced coating systems
Public Abstract
Underground pipelines are protected by a combination of cathodic protection and a protective coating. Multi-layer coatings offer both protection against corrosion and from mechanical damage during construction or during service.
The aim of the proposed work is to improve the performance of multi-layer coatings through an understanding of the factors that affect the level of residual stress in the coating and the consequences for coating disbondment.
