Tubing Hangers

Tubing Hangers are manufactured in a wider variety of types and sizes than any other single component in the wellhead system. They must be configured to meet the needs of a basic completion or the increasingly complex well completion requirements of 21st Century oil and gas wells.

• The Tubing Hanger provides control of the well bore prior to BOP removal
• Suspends the production tubing in the well bore
• Provides the primary annulus seal on the string of tubing being suspended
• Can be manufactured for single or multiple string tubing completions
• Are manufactured with a internal back pressure valve (BPV) profile to seal the ID of the tubing string(s) and provide additional well security prior to BOP removal
• Can be manufactured in configurations including but not limited to, DHCV ports, Chemical Injection ports, Fiber Optic Instrument ports and multiple ESP Penetrator profiles

Tubing Hanger Components

TC-1A-EN (Extended Neck Seal) Tubing Hangers

Yancheng Cyber’s TC-1A-EN tubing hanger is a threaded mandrel type tubing hanger with an extended neck. This hanger utilizes “S” type seals on its neck that are used to seal in the tubing head adapter. This hanger can be configured with interference type ”S” seal or compression packing on the body to affect a annular seal. Lock down screws are used to both energize this packing as well as lock the hanger into the tubing head bowl.

• This isa solid mandrel type tubing hanger that can be installed in the top bowl of any TC style tubing head
• Has OD seals on the extended neck
• Does not require alignment in the tubing head
• Can have a compression type or interference type annular seal
• Can contain premium tubing orspecial landing threads
• Can contain non-continuousporting for control or instrument lines

TC-1A-TMS (Tapered Metal Seal) Tubing Hangers

Yancheng Cyber’s TC-1A-TMS tubing hanger is also a threaded mandrel type tubing hanger that is used for more demanding completion applications. The extended neck of the tubing hanger assembly is sealed at the top by the a tapered metal seal (TMS). The TC-1A-TMS also incorporates metal to metal continuous control line fittings that prevent unwanted leak paths in the SCS SSV line. The annular seal can be an externally energized metal seal (XEMS) using lockdown screws to complete the full metal seal capability of the hanger.

• This is a solid mandrel type tubing hanger that can be installed in the top bowl of any TC style tubing head
• Has OD seals on the extended neck for testing
• Does not require alignment in the tubing head
• Can have a compression type or interference type annular seal
• Can have metal to metal XEMS and/or TMS Seals
• Can contain premium tubing orspecial landing threads
• Can contain special porting for control or instrument lines

BO-2 Coupling Tubing Hangers

Yancheng Cyber’s BO-2 coupling type tubing hanger uses a one piece coupling that is externally threaded with a ACME thread.  The internal landing and suspension threads match the customer tubing specifications. Additionally the BO-2 coupling incorporates a back pressure valve, (BPV) profile in the I.D. The BO-2 coupling is used with the TC-1W pack-off and is system of choice whenever the tubing string needs to be manipulated to set run in conjunction with a TC-1W wrap around type pack-off.

• This is a coupling type tubing hanger that threads into and suspends the tubing from the bottom of the tubing head adapter
• This tubing hanger is used in conjunction with the TC-1W wraparound pack-off whenever the tubing string needs to be moved up, down or rotated to operate the packer in the bottom of the well and still maintain well security
• Can be supplied with BPV locking groove or thread
• Has Acme load bearing threads
• Incorporates secondary seals in the bottom of BO-2 adapter

BO-10 Coupling Tubing Hangers

Yancheng Cyber’s BO-10 coupling type tubing hanger shares all of the same design features as the BO-2 and is generally utilized on completions demanding higher completion shut in pressures. This hanger is a coupling by design but also incorporates a separate rotating, ACME threaded locking nut and is used in conjunction with the TC-1W pack-off.

• The BO-10 coupling is best suited for landing larger trees and any time dissimilar metals may be used for hangers and adapters
• This is a coupling type tubing hanger that suspends the tubing from the bottom of the tubing head adapter
• This tubing hanger is used in conjunction with the TC-1W wraparoundpack-off whenever the tubing string needs to be moved up, down or rotated to operate the packer in the bottom of the well and still maintain well security
• Can be supplied with BPV locking groove or thread
• Has Acme load bearing threads

TC-1W Wraparound Pack-offs

The TC-1W is a split, wraparound pack-off that allows tubing-string manipulation to displace fluid while maintaining complete control of annular pressure. Like all TC Series pack-offs, tubing string weight must be suspended from a tubing suspension adapter or coupling adapter. The TC-1W has a compression-type seal which is actuated by lockdown screws.

• Considered a primary annulus seal
• The compression seal is actuated utilizing lockdown screws
• Lockdown screws also retain the pack-off in position
• Seats in the TCM, TC and TC-60 tubing head bowl
• Is used in conjunction with a tubing thread suspension adapter, BO-2 or BO-10 coupling type hanger

Elastomer Seals & Metal Seals

S-Seals

This style of seal is the most commonly used in the industry. They utilize continuous coil springs that are scaled to the specific sealing requirement and then integrally bonded to the elastomer during the molding process. This eliminates extrusion gaps and weak points around the circumference of the seal and solves problems associated with explosive decompression damage and chemical swell of the seal during use. ”S” seals are designed to be used on all wellhead equipment with machined surfaces up to 15,000 PSI.

• Yancheng Cyber’s proprietary elastomeric compounds are utilized on S-seals
• They can be used in H2S, or CO2 service and are amine resistant
• Are rated for all API material classes including HH
• Are rated for temperature class L-U (-50⁰ F to 250⁰ F)
• Have been performance qualified for API 6A, PR-2, Appendix F

Typical ”S” Seal applications are shown below:

CS-Seals

The CS seal is designed to be used on non-machined, rough surfaces such as that found on the O.D. of oilfield casing. They utilize continuously coiled springs that are scaled to the specific sealing requirement and then integrally bonded to the elastomer during the molding process. These seals are capable of providing a seal across a larger range of tolerances and  extrusion gaps than the S seal. CS seals are available for all API 5CT casing sizes.

• Yancheng Cyber’s proprietary elastomeric compounds are utilized on CS-seals
• They can be used in H2S, or CO2 service and are amine resistant
• Are rated for all API material classes including HH
