A Tubing Head Adapter, or Tubing Adapter, is an important wellhead component which is used to adapt the uppermost connection of the tubing head to the lowermost section of the christmas tree. The tubing head provides a transition from the wellhead to the christmas tree. It can be used for both single and multiple completions. Qihang’s standard tubing head adapters are compatible with a wide range of tubing head spools and tubing hangers. Our adapters come with threaded, flanged, or studded-flange top connections, and most of our tubing head adapters can be machined with a hydraulic supply inlet for downhole control lines.
