Abstract
A pipe having a cylindrical inner wall, a rig end, the rig end having an inner wall having an inside diameter and a remote end. The remote end further comprises a first hemispheric extension that extends from the remote end to at least an outer diameter. A second hemispheric extension connects a surface at an outer cylindrical surface to a pipe exterior wall, wherein the first hemispheric extension and second hemispheric extension form a partial sphere through which, a cavity defined by the inner wall extends.
