Wellhead Equipment: Christmas Tree and Injection Tree

Christmas Tree and Injection tree are intended to seal the wellhead, to suspend well pipelines, to control and monitor the flow of the medium, and to perform the necessary process operations.

The operating mode in the Christmas tree is regulated by an angle throttle, and in the Injection tree by a ball valve or cut-off valve, equipped with replaceable throttling washers.
