Product Overview

DEENPU Tubing Hangers are engineered to provide secure, reliable suspension of production tubing within the wellhead assembly. As the primary structural interface between the tubing string and the wellhead, tubing hangers must withstand the full suspended weight of the tubing, contain well pressure, and provide a reliable annular seal — all while allowing for efficient installation and workover operations.

Our product range includes threaded mandrel type hangers (TC1A, TC1A-B, TC1A-EN, TC1A-CH), wrap-around style hangers (TC1W), and BO-2 couplings. Each type is designed for specific completion scenarios, from simple single-string completions to complex multi-zone installations with control lines. All DEENPU tubing hangers are manufactured from high-quality alloy steel forgings and machined to API 6A dimensional standards.

The TC1A series hangers feature a reliable compression seal actuated by lockdown screws in the upper flange head, providing primary annulus pressure control during Christmas tree installation. The TC1A-CH variant adds integral control line passage for subsurface safety valve or chemical injection applications. The TC1W wrap-around style provides a slick joint solution compatible with BO-2 couplings and B1/B2P adapter bonnets.

How It Works

Tubing hangers serve as the anchor point for the production tubing string at the wellhead. The hanger seats in the tubing head or casing spool bowl, where its external profile mates with the corresponding internal profile in the wellhead component. Once seated, the tubing hanger supports the full weight of the production tubing string hanging below it.

An annulus seal is established between the tubing hanger and the wellhead body. For threaded mandrel type hangers (TC1A series), this seal is a compression-type seal energized by lockdown screws in the upper flange head of the adapter bonnet. The lockdown screws press down on the hanger, compressing the seal against the bowl profile and creating a pressure-tight barrier between the tubing and the annulus.

Once the seal is established, the Christmas tree can be installed on top of the adapter bonnet. The tubing hanger also includes internal preparation for a Type “H” Back Pressure Valve (BPV), allowing the operator to install a BPV before removing the Christmas tree for workover operations. The TC1A-CH variant includes a dedicated control line passage machined through the hanger body, providing a continuous pathway for hydraulic or electrical control lines without compromising the main seal integrity.

TC1A-EN Tubing Hanger

The TC1A-EN is a threaded mandrel type hanger with internal Type “H” BPV preparation. It features a reliable compression seal actuated by lockdown screws that controls annulus pressure during Christmas tree installation.

TC1A-CH Tubing Hanger (with Control Line)

The TC1A-CH is a threaded mandrel type hanger with a dedicated control line passage for subsurface safety valve or chemical injection applications. It features the same Type “H” BPV preparation and compression seal system as the TC1A-EN.

TC1W Wrap-Around Tubing Hanger

The TC1W is a slick joint, wrap-around tubing hanger designed for use with BO-2 coupling and B1 or B2P adapter bonnets. The seal between the pipe and hanger is obtained by energizing the lockdown screws in the upper flange head.

BO-2 Coupling

The BO-2 coupling is used in conjunction with the BO-2 tubing head adapter and the TC-1W tubing hanger. It is a one-piece, externally threaded component with an ACME thread that provides internal top and bottom threads for completions that require string manipulation.

Frequently Asked Questions

What is the difference between TC1A-EN and TC1A-CH? ▼

Both are threaded mandrel type hangers with Type “H” BPV preparation. The key difference is that TC1A-CH includes a dedicated control line passage machined through the hanger body, allowing for subsurface safety valve (SSSV) control lines, chemical injection lines, or electrical conduit without compromising the main annular seal. TC1A-EN does not have a control line passage and is used for standard single-string completions without subsurface control requirements.

When should I use a TC1W wrap-around hanger? ▼

The TC1W wrap-around tubing hanger is the preferred choice for operations that require string manipulation (space-out operations) or for completions where the tubing needs to be run in and landed without a mandrel-type hanger pre-attached. The wrap-around design allows the hanger to be installed around the tubing at the surface and then landed as an assembly. It is used with BO-2 couplings and B1 or B2P adapter bonnets.

What Type “H” BPV preparation means? ▼

Type “H” BPV (Back Pressure Valve) preparation refers to an internal profile machined into the tubing hanger that accepts a standard Type “H” back pressure valve. This allows operators to install a BPV when the Christmas tree needs to be removed for workover operations, preventing well flow during tree removal. The preparation includes the precision-machined seating profile and locking mechanism receptacle per API specifications.

Is the BO-2 coupling compatible with all adapter bonnets? ▼

The BO-2 coupling is specifically designed for use with the BO-2 adapter bonnet and TC-1W tubing hanger as an integrated assembly. It is not compatible with B2P, B1, or TC-series adapter bonnets which use different tubing hanger interfaces. Always verify the compatibility between your coupling, hanger, and adapter bonnet before ordering. Contact DEENPU engineering for assistance with system compatibility verification.

What material certifications are provided? ▼

Standard documentation includes Material Test Reports (MTRs) documenting chemical composition, mechanical properties (yield strength, tensile strength, elongation, hardness), and heat treatment records. Upon request, we provide NACE MR0175 compliance certificates, NDE reports (MPI, UT), and third-party inspection certificates. All material is fully traceable from raw material to finished product.

What is the typical lead time for tubing hangers? ▼

Standard tubing hangers typically ship within 6-8 weeks from order confirmation. Custom configurations or special material requirements may extend lead time to 10-12 weeks. DEENPU maintains an inventory of common configurations for faster delivery. Contact our sales team for current stock availability and expedited delivery options.
