Casing Hangers

WS-22 Casing Hanger


WS-22 is a wrap around Casing Hanger that incorporates pack off, slip bowl and slips. Pack off automatically seals the annulus below the slips when casing load is applied. The WS-22 Hanger's controlled friction reduces casing deflection. WS-22 casing hangers are easy to install and economical.

WS-21 Casing Hanger


WS-21 Casing Hanger combines slips, slip bowl and a type H pack off seal ring. The seal ring provides a positive annulus pack off after the casing has been suspended and cut off.

WS-29 Casing Hanger


WS-29 Casing Hanger provides a high hanging capacity with minimum casing deflection. When the upper slips move down and energize the pack off, the WS-29's non-tapered lower slips engage automatically and apply controlled compression. The lower slips do not move down the pipe and thus do not create the high compressive forces seen in conventional tapered slips. The WS-29 offers far less casing deflection and much greater hanging capacity than other conventional hangers.
