The Precision Well Control Surface Test Tree, or flowhead, is used for well control during deep water completion operations. It has the shortest overall length in the industry, with a patent-pending swivel design that is lightweight and compact, fitting through most v-doors. The surface test tree also comes with landing string crossovers; and is adaptable to different configurations. Designed to meet API 6A requirements.
General information about the Surface Test Tree: The Surface Test Tree (Flowhead) consists of four gate valves: a master valve, two wing valves, and a swab valve. The outlet wing valve is opened and closed using a hydraulic actuator. Above the swab valve is a lifting subassembly (sub) with a threaded connection.
