C Type Oilfield Wellhead Casing Hanger For Supporting The Casing String

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

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

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