FLUID SWIVELS AND PROCESSES FOR PIGGING THERETHROUGH

Abstract: apparatus that include fluid swivels and processes for pigging through the fluid swivels. in some embodiments, the apparatus can include a fluid swivel. the fluid swivel can include a fixed part that defines a first longitudinal fluid path therethrough and a first radial fluid path in fluid communication with the first longitudinal fluid path. the fluid swivel can also include a rotating part that defines a first radial fluid path therethrough. the first longitudinal fluid path can be configured to pass a pig therethrough. the first fixed part and the first rotating part can define a first toroidal fluid path therebetween that can be in fluid communication with the first radial fluid path defined by the fixed part and the first radial fluid path defined by the rotating part.
