Cleaning: Pipelines can accumulate deposits and debris over time, which can reduce flow capacity and increase the risk of corrosion. Regular cleaning is necessary to remove these deposits and maintain optimal performance. Cleaning methods include pigging (using a device called a "pig" to scrape the inside of the pipeline), chemical cleaning, and hydroblasting.
Coating and Cathodic Protection: Corrosion is a major threat to pipeline integrity. Coatings and cathodic protection systems are used to protect pipelines from corrosion. Coatings provide a barrier between the pipeline and the environment, while cathodic protection uses electrical currents to prevent corrosion. Regular inspection and maintenance of coatings and cathodic protection systems are essential for ensuring their effectiveness.
Valve Maintenance: Valves are critical components of pipeline systems, controlling the flow of materials and providing shut-off capability in emergencies. Regular maintenance of valves is necessary to ensure they operate reliably. This includes lubrication, inspection for leaks, and testing of valve operation.
Leak Detection and Repair: Early detection of leaks is crucial for minimizing environmental damage and preventing catastrophic failures. Leak detection methods include visual inspection, pressure testing, acoustic monitoring, and vapor detection. When a leak is detected, it should be repaired promptly using appropriate techniques such as welding, clamping, or sleeving.

Implementing these maintenance activities effectively requires a dedicated team of trained professionals, as well as the right tools and equipment. Furthermore, documentation is key. Every inspection, maintenance task, and repair should be meticulously documented to track the condition of the pipeline over time and identify any trends that may indicate potential problems.
