Abstract
A wellhead flow tee and blow out preventing device having housings joined providing an integral unit. The housing includes a first upper portion with an upper mounting flange on an upper end thereof and a second lower portion with a lower mounting flange on a lower end thereof and a primary central fluid flow passage extending therethrough from one of said flanges to the other. The upper portion has at least one secondary fluid flow passage extending through a sidewall of said housing from said primary passage to an outer surface of said housing and to which external piping is connected. This part of the housing is the flow tee. The second lower housing portion has a pair of oppositely directed passages extending radially outwardly from the central passage to an outer surface of a sidewall of such housing portion. The oppositely directed passages are provided with selectively movable gating members for use in selectively preventing fluid flow through the primary passage. Each of the first and second housing portions having a neck portion surrounding the primary passage with one projecting toward the other and disposed in abutting relation and these neck portions are connected one to the other with a continuous continuity circumferentially around the primary passage.
