Abstract: A fire protection sprinkler with a push-in connection includes a sprinkler body having an input orifice for receiving fluid and an output orifice for outputting the fluid, the body having a push-in connection at the input end and a base portion. The push-in connection is adapted to be connected to a pipe fitting by insertion and has a plurality of recesses, a first recess having a first gasket, a second recess having a second gasket, and a third recess having a retaining clip. A frangible element is held in place by a set screw and a stopper. The frangible element is designed to fail at a predetermined temperature to release the stopper. A deflector is positioned on the base portion and configured to direct the output fluid toward the output end, upon activation of the sprinkler by failure of the frangible element at the predetermined temperature.

Abstract: A subsea heat exchanger is disclosed that includes a production fluid inlet, a production fluid outlet, and first and second heat exchanger units coupled to the inlet and outlet. Each heat exchanger unit includes an outer tubular member, an inner tubular member disposed within the outer tubular member, and an annulus radially disposed between the inner tubular member and the outer tubular member. In addition, each heat exchanger unit includes a bridging assembly coupled between the first heat exchanger unit and the second heat exchanger unit. The bridging assembly includes a connector including a throughbore in communication with the inner tubular member of the first heat exchanger unit and the inner tubular member of the second heat exchanger unit. In addition, the bridging assembly includes a tubular stab that fluidly couples the annulus of the first heat exchanger unit to the annulus of the second heat exchanger unit.
