Piping equipment used in bearing lubricating oil systems for power plants

PROBLEM TO BE SOLVED: To minimize an aperture of pipe without making a gas-phase space on an upstream side of a base pipe and a gas-phase space on a downstream side into a closed state, at a confluent part of liquid flowing in the base pipe arranged obliquely and liquid flowing in a branch pipe connected to the base pipe from above.SOLUTION: A pipe system includes a base pipe 11 arranged obliquely and configured to flow liquid Lha in a state of having a gas-phase space, and a branch pipe 12 connected to the base pipe 11 from above and configured to flow liquid Lhb in a state of having a gas-phase space and make the liquid Lhb confluent with the liquid Lha flowing in the base pipe 11. Gas-phase spaces on an upstream side and a downstream side with respect to a confluent part of the liquid Lha, Lhb from the base pipe 11 and branch pipe 12 always communicate with each other through an internal bypass pipe 13.SELECTED DRAWING: Figure 1
