Sucker-rod wellhead assembly (ASh) and injection (ANK) tree are designed for wellhead sealing, sealing of borehole pipelines suspension and operating medium flow control.
Bypass shall be provided to avoid hook-up piping of backside with blowing line in case head.
Moreover:
- Sucker-rod wellhead assembly may be equipped with casing-head stuffing box enabling to compensate displacement of oil-well pump rods occurring while in operation;
- injection tree may be equipped with:
- ball valve or isolation valves with replaceable chokes;
- phase separators for installation and protection of manometers against unfreezing.
