Surface And Defect Preparation Using Atmospheric Plasma For Non-Metallic Pipe Repair

Composite repair systems’ performance relies heavily on the levels of adhesion between the initial layer of the composite system and the substrate. Enhanced adhesion translates to improved performance of the composite system since better bonding (whether mechanical or chemical) enhances the load transfer from the substrate to the composite layers as well as limit the porosity that would allow liquid or gas molecules to flow through. The aim of this study was to prove quantitatively how the APS atmospheric plasma surface preparation can improve the performance of composite repair systems whether on leaking or nonleaking defects.

Atmospheric Plasma Solutions Inc. (APS) partnered with ADV Integrity, Inc. to conduct a testing program to evaluate the impact of atmospheric plasma surface preparation on the performance of composite systems used to repair defects in transmission pipelines. The APS surface treatment system provides a portable solution for coating removal and functionalizes surfaces to increase adhesion of resins/epoxy/coatings to the underlying substrate. Composite repair systems’ performance relies heavily on the levels of adhesion between the initial layer of the composite system and the substrate. Enhanced adhesion translates to improved performance of composite systems due to increased bonding (mechanical and chemical) which improves the load transfer from the substrate to the composite layers.
