Pig receptacle
View Patent ↗A pig receptacle is provided. The pig receptacle provides a first circular member and a second circular member attached to at least one elongated rod. The first circular member and the second circular member are sized so that they can receive a pig therethrough. A mesh cage is wrapped around the first circular member and the second circular member so that debris can be gathered during the pigging process. The mesh cage defines apertures that are sized so that large pieces of debris are held in an interior cavity formed by the mesh cage, while small pieces of debris can pass through. In this way, debris is transported through the pipeline and is not lost due to abnormalities in the flow rate through the pipeline.
1. A pig receptacle, comprising:
a first circular ring defining an opening therethrough;
a second circular ring having an opening therethrough;
at least one elongated rod connecting the first circular ring to the second circular ring, the first circular ring attached to a first distal end of each elongated rod and the second circular ring attached to a second distal end of each elongated rod;
a mesh cage disposed about each of the first circular ring and the second circular ring, wherein the mesh cage defines an enclosed interior volume;
wherein the mesh cage comprises a plurality of apertures, wherein each aperture is dimensioned to retain debris within the enclosed interior volume;
wherein each of the first circular ring and the second circular ring is dimensioned to receive a pig therethrough.
2. The pig receptacle of claim 1 , further comprising at least one intermediate circular ring disposed between the first circular ring and the second circular ring.
3. The pig receptacle of claim 1 , wherein the mesh cage further covers the second circular ring.
4. The pig receptacle of claim 1 , wherein the first circular ring and the second circular ring have a diameter sized to fit into a receiving station of a pipeline.
5. The pig receptacle of claim 1 , wherein the mesh cage is ellipsoidal in shape.
6. The pig receptacle of claim 1 , wherein the first circular ring and the second circular ring are uniform in circumference.
7. The pig receptacle of claim 1 , wherein the mesh cage is attached around the elongated rod and wraps around an exterior portion thereof.
