Purpose

Injection trees are designed for wellhead setup and sealing of injection wells, tubing string hangers, control and management of the medium injected into the well, performance of production operations, repair and exploratory works. The fittings are equipped with ZD and ZDSh disc valves. Flow is regulated by changing the flow nipples on the ZDSh choke valve. The choke valves are replaced without pressure relieving in the pipeline and with the gate valve closed for 5 minutes.

The weight and dimensions of the fittings are more than half of those of the classic design. Fittings do not have welded joints. Wellhead fittings are completed with shutoff valves according to the customer’s requirements.
