Pipeline inspection is the process of examining pipelines to ensure they are functioning properly and safely. This involves checking for leaks, corrosion, and other potential issues that could lead to failures. Inspections can be conducted using various methods, including visual checks, ultrasonic testing, and the use of drones or robots equipped with cameras and sensors. Regular pipeline inspections are essential for maintaining the integrity of oil and gas transportation systems. They help prevent environmental hazards and costly repairs by identifying problems early. Regulatory agencies often require these inspections to ensure compliance with safety standards and protect public health.
