Method and apparatus for controlling the distribution of two-phase fluids flowing through impacting pipe tees

An apparatus for dividing flow of a primary stream of a mixture of a gas and a liquid over a wide range of flow conditions into a pair of branch streams or pipe arm portions having substantially the same mixture of gas and liquid as said primary stream, which apparatus comprises:

• a pipe tee connector having not less than the same cross-sectional areas in a pipe stem portion and the two pipe arm portions forming said pipe tee connector;
• and
• a vane member in the pipe stem portion of the pipe tee connector which forms two upstream chambers as the mixture enters a tee junction in combination with a nozzle inserted in each of the pipe arm portions wherein each of said nozzles is located directly downstream of the tee junction and the vane member terminates at an intersection of the pipe stem portion with the tee junction.
