CEPAI manufactures tubing/casing heads, hangers and adapter Flanges in all sizes and pressure ratings. The casing head is the lowest part of the wellhead assembly and is always connected to the surface casing string. It supports subsequent drilling wellhead and completion equipment. Popular Adapter Flanges are double studded Adapter Flanges, Companion Flanges, and X Union Adapters. Customers may use Adapter Flanges for transition in nominal size and /or pressure rating. The Adapter Flanges have minimum overall heights, or customer specified thickness, consistent with design considerations. Tree caps are installed on top of Christmas Trees for quick access to the tubing bore-via Tester of Lubricator Adapter for bottom hole testing, installing back-pressure valves etc. Bottom Hole Test Adapters allow a flexible means of entry into the tubing bore. Bottom Hole Test Adapters are used where an integral flanged unit is preferred. These adapters are furnished in various sizes, and working pressure up to 20,000PSI.
