The deposition and growth of scale on the internal surface of oil & gas pipelines is a major challenge in the operation and maintenance of these lines. Pigging and chemical treatment are currently available solutions, but these are expensive, and a permanent passive alternative would be preferable. Diamond Like Coatings (DLC) have shown considerable promise, but the industry remains skeptical in the absence of conclusive evidence. This work addresses the question for a novel super hydrophobic DLC with a parametric evaluation of factors affecting adhesion and growth of common scale groups (such as Calcites and Barites) including surface finish of the substrate, metal composition, and thickness (or presence) of the coating, as well as the differing mechanisms of scale growth where applicable. The approach involves controlled deposition of inorganic scales onto rotational cylindrical electrodes (RCE) under varying conditions of temperature, solution chemistry, flow rates, followed by submerged jet impingement to quantify the corresponding deposit bond strengths and failure modes (cohesion vs. adhesion). Design of Experiments (DOE) methods are used to set and analyze the contribution of deposition and matrix factors simultaneously.

Shawcor's Digital Transformation
As the industry progressively focuses on streamlining processes to reduce risk, project delays and future incidents, Shawcor is developing online information to improve risk management, integrity management and reliability of pipeline assets throughout their lifecycle. Our digital transformation, which we call iLINE, will leverage Shawcor’s material science, technology and expertise to provide traceable, verifiable and complete project data to customers while reducing the need for people in high-risk areas and expensive manual processes. These digital capabilities provide personalized mobile and web experiences tailored for the modern anywhere, anytime, any-device workplace. Let us know your needs and explore how you can leverage our technology to better support pipeline lifecycle management in your projects at OTC.
One of our partners, Vintri Technologies, will be presenting on this topic at the following OTC events. Join us to learn more about our digital quality assurance and material traceability offerings.
