Detail SINGLE BLOK TREE
Delta has manufactured several sizes of Solid Block X-Mas Trees with manually operated valves and actuator operated valves. The range manufactured covers single bores and dual bores. The advantages of going for a solid block tree are reduced overall height, reduced potential leak paths and easier installation. Delta valves can be integrated into tree blocks using API end connections and outlet connections as covered by API 6A. The associated tubing hanger sealing systems are designed accordingly to provide an overall integrated design installation. With the most modern CAD design facilities (Solidworks/ FEA), Delta can quickly produce a design for a desired integral tree block configuration. The single block tree is manufactured to the same high standards and generally from the same materials as Delta valves and can incorporate Delta’s hydraulically operated, wireline-cutting-and-sealing valves. These valves are designed to be fail-safe in an emergency and to cut braided and slickline wires. A variety of proprietary actuators can be offered for this duty. For services where higher corrosion levels may be experienced and/or H25 embrittlement may be expected, integral tree blocks provide an economic solution by means of inconel cladding of bores, sealing areas and valve cavities.
