We can supply different types of tubing spool and tubing hanger in high pressure and crude condition, all the completion well system and equipment can meet or succeed the API 6A standard.

Tubing hangers include three types: Rubber seal, Rubber-Metal seal, and Metal-Metal seal. The Max. Working pressure is 20000Psi, equipped with reliable “Y” type second seal. We also can supply equipments with types of sealing, including the under well control line and seal technology as customer’s requirement.

Reliability of our valves:

• Forging valve bonnet
• Forging valve body
• Low torque
• Hard seal between body and bonnet
• Manual or gear driving operation
• Hard seal between seat and flashboard
• Equipped with switch indicator

Thermal recovery wellhead

Thermal recovery wellhead is composed of Christmas tree and tubing head. The bottom of tubing cross (spool) is connected with bottom in flange type and upper connected to Christmas tree. Flashboard and valve seat is spray welding cemented carbide technique with advantages of high temperature proof, pressure resistance, erosion resistance, abrasion resistance and self-lubricating.
