A pipe is provided to decrease the vortex of the liquid and prevent the noise and the drop of the local pressure in the pipe by mounting plural sheet metals in the pipe. A pipe(5) where the liquid is moved is composed of plural sheet metals mounted in the pipe to prevent the vortex of the liquid. The plural sheet metals are each separated with a predetermined interval and arranged in parallel with the moving direction of the liquid. The plural sheet metals are attached at a support member to be supported in the pipe. The support member is inserted/mounted in the pipe and has the same outer peripheral surface shape as the inner peripheral surface of the pipe.
