PROBLEM TO BE SOLVED: To provide a cyclone flow generating gasket or a cyclone flow generating joint pipe, capable of easily converting fluid being transported in a streamline flow into a cyclone flow in a pipe transport state to be transported, and capable of generating the cyclone flow in a short spacial cycle in the axial direction of a pipeline.;SOLUTION: In a fluid transport passage on which the gasket or the joint pipe is installed, cyclone flow is generated in a pipe of the fluid transport passage where a cylindrical nozzle of the gasket or the joint pipe is inserted by blowing fluid from a side surface blow port of the cylindrical nozzle to its outer side to be diagonally applied to an inside wall surface of the pipe where the cylindrical nozzle is inserted, or cyclone flow is generated by blowing fluid to the inner side of the cylindrical nozzle to be diagonally applied to a circular inner wall surface of the cylindrical nozzle.;COPYRIGHT: (C)2011,JPO&INPIT
