Abstract
A wellhead assembly having an insert that is disposed between a wellhead housing and casing hanger. Axial slots through the insert define a flow path between the wellhead housing and casing hanger. The insert is made from a higher strength material and supports a load exerted between the casing hanger and wellhead housing. The insert is a ring like member, and the slots can more easily be machined in the insert than in the wellhead housing.
