Abstract
A tubular scoop that may be utilized with various assemblies for sampling fluid in a pipeline. The scoop includes a bend with a bend radius that may be from two to four times the diameter of the scoop. The scoop defines a scoop face that is generally parallel to an axis of the tubular of the scoop. The scoop is mountable with a threaded connection that seals around the tubular. An additional seal may comprise a compression nut that allows orientation of the scoop within the pipeline whereupon the scoop orientation is fixed by tightening the compression nut. In one embodiment, the scoop is a single outer tubular with internal bi-directional flow.
Claims17
A bidirectional flow scoop mountable on and into a pipeline for receiving and returning a flowing sample of a fluid from a fluid flow in said pipeline, said pipeline being operable for transporting said fluid that comprises at least one of oil, gas, or petroleum products, said pipeline comprising a pipeline wall defining a pipeline opening, said bidirectional flow scoop comprising:
- an outer tubular comprising a scoop end, a mounting for connection on and into said pipeline opening operable to support said outer tubular when said outer tubular extends into said pipeline to receive said flowing sample of said at least one of oil, gas, or petroleum products, said scoop end comprising a bend that ends with a first opening that extends into said fluid flow, said bend comprises a bend radius in an axis through said outer tubular greater than a diameter of said outer tubular, said outer tubular comprising a first outlet distal said first opening, said first outlet being positioned outside of said pipeline when said bidirectional flow scoop is mounted to said pipeline;
- and
- an internal tubular mounted within said outer tubular, said internal tubular comprising a second opening positioned substantially along said bend, said internal tubular comprising a second outlet distal said second opening, said second outlet being positioned outside of said pipeline when said bidirectional flow scoop is mounted to said pipeline, said outer tubular and said internal tubular of said bidirectional flow scoop being operable to provide fluid flow in two directions internal to said outer tubular when mounted to said pipeline,
- wherein an axis of said internal tubular within said outer tubular is straight at least from said second opening to a shoulder on said outer tubular and said second opening is substantially flush with said bend.
A method for providing a bidirectional flow scoop mountable on and into a pipeline to enable sampling and returning a fluid from a fluid flow in said pipeline, said pipeline being operable for transporting said fluid that comprises at least one of oil, gas, or petroleum products, said pipeline comprising a pipeline connection for said bidirectional flow scoop, comprising the following steps:
- providing an outer tubular that comprises a scoop end which is operable to be mounted on and into said pipeline connection so that said outer tubular extends into said pipeline to receive a flowing sample of said at least one of oil, gas, or petroleum products from said pipeline;
- providing that said outer tubular comprises a bend that leads to a face, said face defining a first opening for said fluid flow, said bend comprises a bend radius in an axis through said outer tubular greater than a diameter of said outer tubular;
- providing that said outer tubular comprises a first outlet distal said first opening, said first outlet being positioned outside of said pipeline when said bidirectional flow scoop is mounted to said pipeline;
- providing an internal tubular mounted within said outer tubular with a second opening positioned substantially along said bend;
- providing that said internal tubular comprises a second outlet distal said second opening;
- providing that said internal tubular has a length so that said second outlet is positioned outside of said pipeline when said bidirectional flow scoop is mounted to said pipeline;
- and
- providing that said outer tubular and said internal tubular of said bidirectional flow scoop are operable to provide fluid flow in two directions internal to said outer tubular when mounted to said pipeline,
- wherein an axis of said internal tubular within said outer tubular is straight at least from said second opening to a shoulder on said outer tubular and said second opening is substantially flush with said bend.
