C-21 Casing Hanger – Wrap-Around Slip Type for Lightweight Applications
Description
CAMTOP C-21 Casing Hanger — Lightweight Applications
The CAMTOP C-21 Casing Hanger is a wrap-around, slip-type hanger engineered for reliable performance in lightweight casing load applications. As a non-automatic sealing solution, it is designed to be used with a separate seal assembly, providing flexibility for various wellhead configurations. Its simple, robust design ensures secure casing support in a wide range of operational scenarios.
Key Features and Applications
- Non-Automatic Sealing System
- Designed for Lightweight Casing Loads
- Wrap-Around Installation
- Field-Proven Reliability with a track record spanning more than three decades
The C-21 is engineered to provide a secure, cost-effective solution for specific wellhead applications. Its design offers operational flexibility through a non-automatic sealing system, is optimized for lightweight casing loads, and ensures simple, fast installation.
The H-Packoff Seal Assembly
The C-21 Casing Hanger is designed to work in conjunction with the H-Packoff, its corresponding seal assembly. The H-Packoff creates the necessary seal on the inside and outside diameter of the casing hanger recess. This two-part system provides a reliable, non-automatic seal that is energized separately from the casing hanger slips. CAMTOP offers H-Packoff assemblies in a full range of standard API casing sizes to complete your C-21 installation.
