Title:
PIPING CONNECTING STRUCTURE COMPRISING MULTI-DRILLED PIPE AND A PLURALITY OF BRANCH PIPES, AND BRANCH PIPE FORMING METHOD
Document Type and Number:
Japanese Patent JP2006329411
Kind Code:
A
Abstract:
To provide a piping connecting structure capable of making fluid flow smoothly between a multi-drilled pipe and branch pipes connected to the multi-drilled pipe.
Inserting ends of the branch pipes 10 are inclined with respect to the insertion direction of the branch pipes 10 into the multi-drilled pipe 1. Thereby, when each of the branch pipes 10 is inserted into a communication hole 4 at the end of the multi-drilled pipe 1, because the insertion ends of the branch pipes 10 are inclined, passage resistance of the insertion parts can be reduced in comparison with a case where the insertion ends are orthogonal to the insertion direction. Therefore, fluid can be made to smoothly flow between the multi-drilled pipe 1 and the branch pipes 10.
