C-29 Casing Hangers
The GBI C-29 Casing Hanger is a high-capacity, wrap-around, slip-type hanger designed for medium to high casing load applications. It features an automatic packoff seal and a unique dual-slip design that safely controls casing deflection under heavy loads. This makes the C-29 the ideal solution for deeper wells or heavier casing strings where wellbore integrity is paramount.
Key Features and Applications
The GBI C-29 is engineered to provide maximum security and reliability in demanding wellhead environments. With a successful track record of over 35 years, it is a globally trusted component for its safe load distribution and easy installation. Its key features include:
- Dual-Slip Load-Sharing Design
- High Casing Load Capacity
- Automatic Packoff Seal
The Dual-Slip Advantage for High Casing Loads
The core feature of the C-29 is its two sets of load-sharing slips. Unlike single-slip hangers, this design distributes the heavy weight of the casing string across two contact points within the wellhead bowl. This even distribution minimizes stress concentration on the casing body and reduces the risk of casing deflection or damage. The result is a safer, more secure installation that protects the long-term integrity of the well, especially in applications with high casing loads.

FAQs
Both are automatic sealing hangers, but the C-29 is designed for higher loads. The main difference is that the C-29 uses two sets of load-sharing slips, while the C-22 uses a single set. This makes the C-29 better suited for heavier casing strings.
The dual-slip design improves performance by distributing the casing weight more evenly across the wellhead bowl. This reduces peak stress on the casing pipe and prevents it from deforming or deflecting, which is critical for maintaining well integrity under high loads.
You should choose a C-29 when dealing with heavier casing strings, deeper wells, or when engineering specifications call for a higher load capacity to ensure a greater margin of safety. Our commitment to meeting these specifications is verified by our quality certifications.
