摘要 <p><P>PROBLEM TO BE SOLVED: To provide a pipe with a blade for generation of a swirling flow, which makes a swirling-direction flow generated in water flowing down while keeping a flow velocity in a pipeline constant. <P>SOLUTION: A pipe 1 with an agitating blade, which includes a cylindrical pipe body 2 and a plurality of blade bodies 8, 8... protrusively provided on the inner peripheral surface of the pipe body 2, makes a swirling-direction flow generated in a fluid flowing down in the pipe body 2. Each of the blade bodies 8, 8... is formed in a shape sequentially twisted at each predetermined angle toward an outlet side from an inlet side, and an inlet-side edge is formed in a shape inclined toward the outlet-side center. <P>COPYRIGHT: (C)2013,JPO&INPIT</p>
