DUAL BLOCK TREE

Delta can provide customers with several sizes of Dual Block X-Mas Trees having manual operated valves and actuator operated valves. The purposes of using Dual Bores is producing oil from different levels inside the same well and using it for multi-lateral drillings. Delta valves can be integrated into tree blocks using API 6A standards. 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. This 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 as indicated opposite. These valves are designed to fail-safe in an emergency and to cut braided a slickline wire. A variety of proprietary actuators can be offered for this duty. For services where higher corrosion levels may be experienced and/or H2S embrittlement may be expected, integral tree blocks provide an economic solution by means of Inconel cladding of bores, sealing areas and valves cavities.
