C-22 Casing Hanger – Automatic Sealing Slip Type for Medium Load
Description
CAMTOP C-22 Casing Hanger — Automatic Sealing, Medium Load
The CAMTOP C-22 Casing Hanger is a wrap-around, slip-type hanger that provides an automatic sealing solution for medium casing load applications. This model features an integrated packoff seal that is energized by the casing weight, simplifying installation and enhancing operational reliability. It is a field-proven solution trusted by wellhead manufacturers for its efficient and secure performance.
Key Features and Applications
- Automatic Packoff Seal
- Medium Casing Load Capacity
- Compact and Efficient Design
- Field-proven with over 35 years of equivalent service history
The Automatic Packoff Seal Advantage
The key feature of the C-22 is its integrated automatic packoff seal. Unlike non-automatic hangers that require a separate seal assembly, the C-22’s sealing element is built directly into the hanger body. The seal is primarily energized by the weight of the casing string as it is landed, which compresses the seal to create a secure barrier. Lock screws provide a secondary energizing mechanism. This design simplifies installation, reduces rig time, and provides a reliable seal with minimal operational complexity.

FAQs
What is the main difference between a C-22 and a C-21?
The main difference is the sealing mechanism. The C-22 features an integrated, automatic packoff seal that is energized by casing weight. The C-21 is a non-automatic hanger that requires a separate, manually energized seal assembly like an H-Packoff.
How is the C-22’s automatic seal energized?
The automatic seal is primarily energized by the casing string’s weight, which compresses the sealing element as the hanger lands in the wellhead bowl. Lock screws can be used to apply additional force as a secondary energizing method.
What material and temperature specifications are available?
The C-22 is available in all standard API material classes (AA-HH) and temperature ratings (P-U).
