Abstract
Present embodiments are directed to a circulation system including a circulation management system. A housing of a coupling feature of the circulation management system is configured to extend over a box end of a pipe element. A seal disposed within the housing is configured to engage with a face of the box end. A force-application feature is configured to force the seal against the face of the box end to establish a sealed engagement between the circulation management system and the pipe element. A flow path of the circulation management system extends through the housing and the seal, wherein the flow path facilitates fluid flow into the pipe element from the circulation management system when the sealed engagement is established. A port to the flow path is configured to couple with a fluid flow supply feature.
