J-Tube and Pull-Thru Pigs

J-Tube Pigs (also called Pull-thru pigs) are a style of pigs that are designed to be pulled through the pipeline using a wire. They are used extensively during offshore J-tube cleaning and gauging operations (prior to pipeline riser pull-in operations or NDT inspections) as well as during onshore factory acceptance tests of pipeline spools and manifolds.

Propipe supplies a range of pigs that can be used for these cleaning and gauging operations and the pigs are designed to suit all manner of shackles and wireline tethers. The pigs can be designed for light interference (where there are unknown levels of debris and corrosion) through to heavy duty pigs, with aggressive scale removal systems. They can also be configured to carry Propipe’s SMART Gauge System with oversized flexible gauge plate, allowing detailed inspection after each cleaning pig run.
