iSystems Industries’ pig launchers are essentially pressure vessels used for launching of a pipe pig or a pig tool into the pipeline for cleaning or inspection purpose. After being launched into the pipeline, the pig tool is pushed through the pipeline by a driving fluid. The pipeline is cleaned along the way by brushing action from the pig. On the other end the pig tool is received by a pig receiver. Pig receiver is also a vessel used for receiving the pipe pig tool. Pig launchers and receivers are designed to meet the specific requirements of a pipeline.

The pig launchers & receivers we fabricate range from simple barrel pig launchers and receivers through to complete skid mounted units with associated equipment including actuated valves, quick opening closures, instrumentation, pig signalers and control systems. They can be of horizontal, vertical or inclined type. For ease of operation, horizontal pig traps are preferred. When space constraints become critical, vertical or inclined pig traps are installed instead of horizontal.

All units are designed and fabricated to relevant required pipeline and vessel design codes like;
• ASME B31.3, B31.4, B31.8
Pig launchers and pig receivers are produced in a range of materials, from low strength carbon steel, to high strength carbon steel, and where specified, stainless steel, duplex stainless steel and carbon steel internally clad with corrosion resistant inconel materials for different sizes and pressure class.
