Pigging - launchers and receivers
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.
Lessons include:
- Reasons to pig
- Pig types
- Pig selection, design, and maintenance
- In-line inspection pigging requirements
- Pigging operational considerations
- Pig trap operations, inspection and maintenance
- Pig handling equipment
Various pig trap installations, including:
- General considerations
- Service conditions and code requirements
- Pressure and instrumentation requirements
- Valves
- Barrel design
- Pig trap end closures
- Materials, fabrication, welding, and marking
- Special applications
