Wellhead Christmas Tree – API 6A
DEENPU API 6A Christmas Tree is the valve-and-spool assembly installed on top of the wellhead to control and direct the flow of oil, gas, or injection fluids. Designed, manufactured, and tested in full compliance with API Spec 6A (21st edition) and NACE MR0175 / ISO 15156, our trees are supplied for production wells, injection wells, geothermal wells, and well-testing operations worldwide.
Each tree is configured to order with gate valves, chokes, and instrumentation to match the well’s pressure rating, material class, and service environment. Both solid-block and composite (spool-type) constructions are available, in single-wing and dual-wing layouts, with manual, hydraulic, or pneumatic actuation.
