Well Head & Christmas Tree Equipment — API SPEC 6A COMPLIANT

The casing head is a fundamental component of the wellhead system. Installed at the top of the surface casing, it provides structural support and serves to suspend and seal the casing strings. As the base section of the wellhead assembly, it plays a critical role in ensuring well integrity and safe drilling operations. 

The casing spool is designed to support the weight of both the intermediate and production casing strings while providing effective sealing of the annular space between casings. It also serves as a transition connection for installing blowout preventers (BOPs), tubing heads, and other upper wellhead equipment. Engineered for strength and reliability, the casing spool is a critical component for safe and efficient well control operations. 

The casing hanger is installed within the upper flange bore of the casing head or casing spool. It uses wedge-shaped slip teeth to grip and suspend the casing string securely in place. Relying on the weight of the casing string, it activates the sealing mechanism to effectively isolate and seal the annular space between casing layers, ensuring a reliable pressure barrier within the wellhead system. 

Installed beneath the casing head, the casing head base connects the casing head to the surface casing or conductor pipe. It utilizes external connecting bolts to apply force, enabling the slip teeth to securely grip the casing. This ensures a stable and pressure-tight foundation for the wellhead system, enhancing both operational safety and structural integrity. 

Installed into the upper flange bore of a casing head or casing spool, this mechanical seal casing hanger uses wedge-style slips to generate gripping force, securely suspending the casing string. The sealing mechanism is manually activated by tightening screws, providing a dependable seal in the annular space between casing layers—ensuring operational safety and pressure integrity. 

Installed into the upper flange bore of a casing head or casing spool, this hanger suspends the casing string via threaded lower casing connection. Sealing is activated by the weight of the casing and the compressive force from the set screws, ensuring reliable isolation of the annular space between casing layers.

Design Features:

• Primary Seal Options: Available with either metal-to-metal or non-metallic primary sealing elements.
• Neck Profile: Smooth neck design forms a secondary seal when connected with upper wellhead equipment, enhancing sealing reliability.

The tubing head spool is a critical component installed above the uppermost casing head and below the production (oil or gas) tree. It is designed to suspend the production tubing and effectively seal the annular space between the tubing and casing. In addition to supporting downhole tools, the tubing head ensures pressure integrity and provides access for well servicing operations. Its robust construction is essential for safe and efficient wellhead performance. 

Installed above the tubing head, the Christmas tree is designed to control and regulate the flow rate and wellhead pressure of oil and gas wells. It also directs the production flow to downstream pipelines for processing and transportation.

Available Configurations:

• Structure: Single-wing or dual-wing design
• Choke Valve Type: Adjustable or fixed choke options
   

Engineered for reliability and performance, the Christmas tree is a vital component for safe and efficient well control.
