Abstract
A remediation pig for cleaning a pipeline of wax or paraffin mechanically, with heating, and/or with jetting, comprising a body having an axis, an impeller mounted in the body to receive power from the flowing fluid within the pipeline, wheels mounted on the body for contacting the internal bore of the pipeline, the wheels being powered by the power received from the impeller and being mounted in a skewed position relative to a plane perpendicular to the axis such that as the wheels roll on the internal bore the remediation pig will move along the pipeline.
Claims17
A remediation pig for cleaning a pipeline of wax or paraffin, comprising
- a body having an axis,
- an impeller mounted in said body to receive power from the flowing fluid within said pipeline,
- wheels mounted on said body for contacting the internal bore of said pipeline, said wheels being powered by said power received from said impeller and being mounted in a skewed position relative to a plane perpendicular to said axis such that as said wheels roll on said internal bore said remediation pig will move along said pipeline,
- further comprising one or more rotating cutters proximate one end of said remediation pig to remove said wax from said bore.
A remediation pig for cleaning a pipeline with a flowing fluid of wax or paraffin plated on the inner bore of said pipeline, comprising
- a body having an axis,
- an impeller mounted in said body to receive power from the flow within said pipeline,
- wheels mounted on said body for contacting and being loaded against the internal bore of said pipeline, said wheels being powered by said power received from said impeller and being mounted at an acute angle relative to a plane perpendicular to said axis such that as said wheels roll on said internal bore said remediation pig will move along said pipeline,
- further comprising the loading of said powered rollers said loading of said wheels against said inner bore of said pipeline is relieved by pushing on a first end of said remediation pig.
