Performance Evaluation of Corrosion Inspection Robot (CIR) for Pipelines and Tunnels

Abstract

Corrosion inspection is a process that evaluates and monitors the corrosion of equipment components, structures, process units, and facilities. Monitoring infrastructure facilities seek to identify specific conditions to extend the life and serviceability of assets while increasing safety and reducing replacement costs. Corrosion is the unintentional destruction of a metallic substance caused by direct chemical and electromechanical reactions with its environment that starts at the surface. This study presents an evaluation of the performance of a developed Corrosion Inspection Robot (CIR) for pipeline and tunnel corrosion monitoring. It involved a variety of materials as components for the robotics corrosion inspection system. There are numerous analysis parameters for the mobility of system functionality. The corrosion inspection robotic system was used to inspect and investigate the type of corrosion in a 340 mm diameter pipe with a thickness of 3 mm. With the aid of the ultrasonic sensor, the types of corrosion that occurred in the tested pipe were uniform, pitting, galvanic, and atmospheric corrosions, with corroded depths ranging from 0 to 590 mm. The Corrosion Inspection Robot (CIR) performed effectively and efficiently, according to the performance evaluation. This corrosion inspection robotic system is suitable for corrosion inspection and monitoring in water corporations, petrochemical industries, and the marine sector.
