PIPE STRUCTURE OF BRANCH PIPE LINE

摘要

A water piping arrangement of a branch pipe 12 connected to a main pipe 22, for allowing water to flow therethrough, has cavity flow inhibiting means 30 provided between the main pipe 22 and the branch pipe 12, for avoiding adverse effect to the piping system based on a thermal stratification which is formed by-a cavity flow which is generated in a closed pipe branched from a main pipe.
