Use of a proper pigging program with the correct pig helps maintain the integrity and optimum efficiency of the pipeline while safeguarding both the environment and the pipeline asset.
Maintenance of a clean pipeline is important, as buildup of solids impacts throughput. Build-up of deposits can also create conditions for corrosion by reducing the effectiveness of inhibitors.
Students have the opportunity to demonstrate proficiency in the in-line inspection, or pigging, process using the launcher and receiver traps on our small scale pipeline system.
