Abstract
The adapter, blow-out preventer housing and flow tee of an oilwell wellhead assembly are formed together as a one-piece or integral structure. The structure has a bottom flanged connection and a top studded and internally threaded connection. By eliminating threaded connections and the adapter body, the length of the combined assembly is reduced by about 50% and structural strength is improved.
