Effect of Surface Preparation on Residual Stress in Multi-layer and Other Pipeline Coatings

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 .
