Abstract

PROBLEM TO BE SOLVED: To provide a suction pipe capable of easily carrying small chippings, dust and the like. SOLUTION: A cylindrical coil member 3 wound at preset pitches is mounted on the inner periphery side of a pipe member 2. In a suction pipe 1, a laminar flow 4 which flows on the inner periphery side of the coil member 3 to the axial direction of the pipe member, a swirl flow 5 which flows along the spirally winding direction of the coil member 3 and a turbulent flow 6 which arises with part of the laminar flow 4 blanching between the pitches of the coil member 3 (between adjacent wire materials) are thus generated. Chippings, dust and the like attempted to adhere on the inner periphery side of the pipe member 2 are swirled by the turbulent flow 6 and carried by the laminar flow 4 and the swirl flow 5.
