The W wraparound slip casing hanger is a step tapered design able to support extreme casing weights greater than rated joint strengths without the possibility that the casing will collapse from tensile loading.
The ‘WE’ wraparound slip hinged casing hanger is used when casing weight is insufficient to energize the ‘W’ casing annulus seal. The sealing element is located above the slips and is mechanically activated by cap screws independent of the casing string load on the slips.
