Description
Product Description
The double cone double cylinder liner hanger is a downhole completion tool used to suspend liner strings inside the previous casing during oil and gas well completion operations. It is designed to provide reliable liner suspension, stable hydraulic setting, and strong load-bearing performance in demanding downhole environments.
This hydraulic liner hanger system adopts a double cone and double cylinder structure. The double cone design helps improve slip expansion and anchoring stability, while the double cylinder mechanism provides stronger and more reliable hydraulic setting force. This makes the tool suitable for long liner strings, highly deviated wells, horizontal wells, deep wells, and complex liner cementing programs.
In liner running and cementing operations, problems such as incomplete slip setting, insufficient hanging capacity, landing failure, restricted circulation, or poor sealing may cause costly non-productive time and well completion risks. Our double cone double cylinder hydraulic liner hanger is designed to improve setting reliability, reduce operational uncertainty, and support stable liner suspension under challenging well conditions.
The tool can be manufactured from AISI 4130 / 4140 H2S-resistant alloy steel according to well conditions and customer requirements. It is designed with reference to API Spec 5CT casing and liner connection requirements, supporting reliable matching with casing strings, liner strings, API threads, and premium thread connections.
For sour gas wells or corrosive downhole environments, H2S-resistant material options can be supplied upon request. An optional top packer is also available when additional sealing performance is required above the liner hanger.

Product Features & Benefits
Double Cone Structure for Stable Slip Expansion
The double cone structure helps improve slip expansion and anchoring stability. It allows the liner hanger to distribute load more effectively inside the casing and improves liner suspension reliability during completion operations.
Double Cylinder Hydraulic Setting
The double cylinder design provides stronger hydraulic setting force, helping ensure reliable downhole activation. This is especially useful in complex wells where stable setting performance is critical.
Large Slips for Long and Heavy Liners
Large slips are designed to support long liner strings and heavy liner loads. This helps improve hanging capacity and reduces risk during liner running and cementing operations.
Premium Slip Protection During Running
Premium slips are protected during casing running, reducing the risk of premature slip damage before the tool reaches the setting depth.
Big Flow Area for Better Circulation
The big flow area helps improve fluid circulation and cementing performance, especially in highly deviated and horizontal wells where circulation efficiency is important.
Special Landing Collar Design
The special landing collar design helps reduce the risk of landing failure and supports more reliable operation during liner running.
Optional Top Packer
An optional top packer can be supplied when additional sealing performance is required above the liner hanger. This helps improve completion integrity and zonal isolation.
AISI 4130 / 4140 H2S-Resistant Alloy Steel
The liner hanger can be manufactured from AISI 4130 / 4140 H2S-resistant alloy steel, providing strong mechanical performance, impact resistance, and improved reliability in harsh downhole environments.
API Spec 5CT Connection Compatibility
The tool can be designed with reference to API Spec 5CT casing and liner connection requirements, supporting reliable matching with casing strings, liner strings, API threads, and premium thread connections.
Suitable for Complex Well Conditions
This liner hanger is suitable for highly deviated wells, horizontal wells, deep wells, and complex completion projects where conventional liner hanger systems may face running or setting challenges.
Applications
The double cone double cylinder liner hanger is widely used in:
Oil and gas well completion
Liner running operations
Liner cementing operations
Long liner suspension
Highly deviated wells
Horizontal wells
Deep well completion
Sour service wells upon material selection
Onshore and offshore well construction
Casing and liner connection systems
