CASING HANGERCASING HANGERC-21 Casing HangerSlips, slip bowl and a type H pack off seal ring are allcombined in the CG-21. The Type “H” pack off provides apositive annulus pack off after the casing has beensuspended and cut off.C-22 Casing HangerCombined in a single unit, the C-22 wrap aroundCasing Hanger incorporates pack off, slip bowl and slips.when the casing load is suspended, the pack offautomatically seals the casing annulus below the slips. TheC-22 Hanger’s controlled friction reduces casingdeflection, can be easily installed and is economicalThe C-29 Casing HangerProvides high hanging capacity with minimum casing deflection. When the upper slips move down and energize the pack off, the C-29’s non-tapered lower slips engage automatically and apply controlled compression.The CG-29 offers far less casing deflection and much greater hanging capacity than other conventional hangers.

TUBING HANGERTUBING HANGERT-2W Tubing HangerThe T-2W Wrap-Around Tubing Hanger is designed tomaintain control of the tubing/casing annulus while allowing reciprocation of the tubing.

The T-M tubing hanger is a high capacity, mandrel tubingHanger pressure rated to 15,000 psi. The design of theTubing hanger must be compatible with the bowl it lands in And the adapter to which it attaches.The tubing hangers and the tubing head adapters havebeen linked by nomenclature to make pairing them together easier. For the TG-M model, the ‘T’ represents the tubing head bowl design and the ‘M’ represents the tubing hanger
