Tubing Head Adapter

Providing a transition from the wellhead to the tree, the tubing head adapter is used for both single and multiple completions. Neeco’s standard tubing head adapter product line consists of three models, each designed to work with a set group of tubing heads and hangers. With threaded, flanged, or studded-top connections, most adapters can be machined with a hydraulic supply inlet for downhole control lines.

A-4N
Considered “seal bore adapters” these products have the inside diameter (ID) machined to provide a controlled seal bore for an “extended-neck” tubing hanger or seal nipple. Capable of possessing a test port and/or a hydraulic supply inlet for control lines, seal bore adapters are more commonly used in advanced applications.

BO-2N
Known as the coupling-type adapters, the BO-2N provide a means to suspend the tubing in conjunction with a special coupling. Creating a lower connection for the tubing head and an upper connection for the tree, the coupling also accepts a BPV.

The BO-2N is installed as an entire assembly by rotating it onto the coupling, and is used as a studded top connection only.

B-1N

A simple transition piece between the wellhead and the tree, the adapter hangs no load nor provide a controlled seal bore. The smooth seal bore on a tubing head is used when tubing is suspended from the tubing hanger. For low-pressure completions, these tubing hangers are not designed for tubing string manipulation or control lines. This adapter can be furnished with studded or threaded upper connection for mating to Christmas tree.
