Recent research published in ‘Cailiao Baohu’, which translates to ‘Materials Protection’, has unveiled critical insights into corrosion coupon monitoring that could significantly impact the construction and petroleum sectors. Led by WU Linshuang and a team from Southwest Petroleum University and the Xinjiang Oilfield Company, the study employed a sophisticated three-factor, three-level orthogonal experiment using a multiphase flow corrosion loop (MPFC) to analyze the effectiveness of corrosion monitoring methods.
Corrosion is a pervasive issue in construction and oil production, leading to costly repairs and safety hazards. This research identifies that the effectiveness of corrosion coupons—devices used to measure corrosion rates—depends heavily on three main factors: installation depth, flow rate, and temperature. The findings indicate that the average corrosion rate of the coupons was not only higher than that of the pipe walls but also showed a positive correlation with these factors. “Our results clearly demonstrate that installation depth is the most critical factor, followed by flow rate and temperature,” stated WU Linshuang.
The implications of these findings are profound for the construction industry, particularly in the management of infrastructure that is susceptible to corrosion. By optimizing the placement of corrosion coupons based on the study’s insights, companies can enhance the accuracy of their monitoring systems, leading to better maintenance strategies and reduced operational costs. This is especially pertinent in environments where high flow rates and varying temperatures can accelerate corrosion processes.
Additionally, the research employed Fluent finite element simulation to corroborate their experimental findings. The simulations revealed that both the surface flow velocity on the coupon and the length of the recirculation zone increased with installation depth, further emphasizing the importance of proper placement. “Understanding the flow dynamics around the coupons allows us to refine our monitoring techniques and potentially extend the lifespan of critical infrastructure,” WU added.
As the construction and oil production sectors continue to grapple with the challenges of corrosion, this study provides a pathway for more effective monitoring strategies. By prioritizing installation depth and understanding the interplay of flow rate and temperature, companies can mitigate risks associated with corrosion, ultimately leading to safer and more durable structures.
The research team’s affiliation with prominent institutions like the Petroleum Engineering School at Southwest Petroleum University and the Baikouquan Oil Production Plant positions them at the forefront of addressing corrosion challenges in the industry.
