scarce water

Aegion Coating Services completed a project at the Candelaria open-pit copper mine near the mining and agriculture town of Copiapo, Chile. The project consisted of the application of the coating of nearly 4,600 internal field joints along more than 50 miles of 24-inch-diameter pipeline. The primary goal of the project was to coat the joints to prevent leaks of the process water line. This would help to protect scarce water in the desert climate. Aegion Coating Services was able to complete the project using its revolutionary robotic coating system.


The Candelaria coating project faced several challenges. Environmental challenges, such as the desert’s dust, required the entire length of pipe to be cleaned multiple times prior to the coating process. The entire length of each pipe was inspected in addition to a standard internal field joint inspection using circumferential line-travel holiday detecting equipment. Located on the inspection machine, the detection equipment was used to inspect the lining of each pipe after the internal field joints were completely cleaned, coated, visually inspected and holiday inspected. Real-time feedback provided the field technician with immediate verification of each pipe section’s quality status and detection of any anomalies in the factory-coated pipeline. When holidays were found, the required repairs were made.
