Injection Wellhead Equipment

TU 3665-009-49652808-2004

It is intended for wellhead sealing and controlling of its operational mode.

It is equipped with safe, easy-to-use and highly proof disk gate valves ZD-type.

To perform step control of the flow (for ANK1Sh) it is equipped with disk choke gate valves ZDSh. It takes 3-5 min. to change chokes in the disk choke gate valve ZDSh by one operator with the disk gate in the closed position without pressure release.

Alloys and materials used guarantee high resistance to wear and corrosion.

Can be transformed to the injection type ANK.

Climatic category of the wellhead equipment — UHL(HL1) in accordance with the national standard GOST 15150-69.

Temperature ranges +40°C −60°C.
