PURPOSE: To suppress the generation of unsteady wall temperature fluctuation caused by the heat transfer of two fluids with large temperature difference and unsteady thermal stress generated in association so as to provide mixed flow piping higher in safety and reliability by using a double/triple temperature difference reducing system.
CONSTITUTION: By-pass structure is provided from a main pipe 1 after confluence to a branch pipe 2, and a throttle part 4 is installed in the branch pipe shape around the lower reaches outlet of a by-pass pipe 3. A fluid is made flow into the by-pass pipe 3 by the drop of pressure due to the throttle part 4, and the fluid in the branch pipe 2 and the fluid in the by-pass pipe 3 are mixed before the fluid in the branch pipe 2 and the fluid in the main pipe 1 are mixed.
