The Tubing Head Adapter is the component that allows for the Christmas tree or other completion equipment to be connected to the tubing head. The designs and types of tubing head adapters are continually evolving in order to meet the new technological needs of the customer’s completion requirements. Tubing head adapters:
- Can provide both the primary production tubing seal and the secondary annulus seal on the completion tubing string
- Can be used to actually suspend the weight of the tubing string
- Can be manufactured for single or multiple string tubing completions
- Can be manufactured in configurations including but not limited to, DHCV ports, Chemical Injection ports, FiberOptic Instrument ports and multiple ESP Penetrator profiles
Tubing Head Adapter Components
B-1 Tubing Head Adapters
Yancheng Cyber’s B-1 adapters can hang tubing utilizing tubing threads machined into the bottom ID of the flange. These are employed when an operator wants to reciprocate tubing as part of the completion process. Additionally they can be used as a non-suspension adapter when employed with the TC-1A or TC-1A-BP tubing hangers. They are used with threaded valves in low pressure applications.
- Are normally used in conjunction with the TC-1W wrap-around or TC stripper pack-off
- Are for use with threaded valves
- Can be utilized with the TC-1A, or TC-1A-BP tubing hanger and seal sleeve
- Are equipped with a test port for testing the flanged connection utilizing the TC-1A or TC-1A-BP tubing hanger and seal sleeve
- They cannot be used for multiple tubing string completions
- Cannot accommodate ports for hydraulic, power supply or instrumentation
Type | Flange Size | Tubing Size | WP | PSL Levels | Material Classes |

B-2-P Tubing Head Adapters
Yancheng Cyber’s B-2-P adapters can also suspend tubing utilizing threads machined into the bottom ID of the flange. They are employed when an operator wants to reciprocate tubing as part of the completion process, or can be utilized as a non-suspension adapter when used with the TC-1A or TC-1A-BP tubing hanger They are used with flanged gate valves in low to medium shut-in pressure applications
- Are normally used in conjunction with the TC-1W wrap-around or TC stripper pack-off
- Are for use with flanged valves
- Can be utilized with the TC-1A, or TC-1A-BP tubing hanger and seal sleeve
- Are equipped with a test port for testing the flanged connection utilizing the TC-1A or TC-1A-BP tubing hanger and seal sleeve
- They cannot be used for multiple tubing string completions
- Cannot accommodate ports for hydraulic, power supply or instrumentation
Type | Bottom Flange Size | Tubing Size | Top Flange Size | WP | PSL Levels | Material Classes |
B-2-P | 7″ | 2-3/8” thru 3-1/2” EUE | 2-1/16” thru 3-1/8” | 2K, 3K, 5K | PSL 1 thru 3 | AA, DD, EE |
BO-2 Adapters
Yancheng Cyber’s BO-2 adapter is another example of a suspension adapter. It is designed with an internal ACME thread that allows for the Sentry BO-2 coupling to be threaded in the bottom of the adapter and sealed with an internal O-ring. These adapters also employ the TC-1W wrap-around pack-off. They are employed when an operator wants to reciprocate tubing as part of the completion process.
- Isutilized for medium to high shut pressure applications
- Is designed with an internal O-ring seal
- Is supplied with test ports for testing
- They do not allow for multiple tubing string completions
- Are not used for severe service completions
Type | Bottom Flange Size | Tubing Size | Top Flange Size | WP | PSL Levels | Material Classes |
BO-2 | 7″ | 2-3/8” thru 3-1/2” EUE | 2-1/16” thru 3-1/8” | 2K, 3K, 5K, 10K | PSL 1 thru 3 | AA, DD, EE |
BO-2 | 11″ | 4-1/2” EUE | 4-1/16” | 5K, 10K | PSL 1 thru 3 | AA, DD, EE |
BO-10 Adapters
Yancheng Cyber’s BO-10 adapter is the solution for extreme tubing string weight applications for a coup[ling type adapter. This adapter is designed with an ACME load nut for larger trees. This allows for the tree to be made up without rotating the tree and prevents any thread galling that may occur between dissimilar NACE coupling and adapter materials. Additionally, it incorporates internal ”S” seals on the upper extended neck. Like the BO-2 these adapters also employ the TC-1W wrap-around pack-off. This system is employed when an operator wants to reciprocate tubing as part of the completion process.
- Is utilized for critical high shut pressure applications
- Is designed with the internal S-seal good to 15K
- Is supplied with test ports for testing
- They do not allow for multiple tubing string completions
Type | Bottom Flange Size | Tubing Size | Top Flange Size | WP | PSL Levels | Material Classes |
BO-10 | 7″ | 2-3/8” thru 3-1/2” EUE | 2-1/16” thru 3-1/8” | 10K and 15K | PSL 1 thru 3 | AA, DD, EE, FF |
A-5-P Adapters
Yancheng Cyber’s A-5-P adapter is an economical choice for a seal bore adapter. This assembly has a flanged bottom allowing it to connect directly to a tubing head with a studded top connection. This adapter is best suited for medium to high pressure shut in well pressure applications and is available in larger flange sizes.
- This adapter has a flanged bottom and studded top
- Is available with non-continuous DHCV or Chemical Injection line
- Is available in larger flange sizes
