Title: Muffling fluid pipe
Inventor: NOMURA YUJI
IPC: F16L9/18
Filed: 1997-07-12
Abstract: PROBLEM TO BE SOLVED: To provide a muffling fluid pipe inserted into a sheath pipe inner surface by forming protruded parts of various kinds of shapes on an outer peripheral surface of a fluid pipe. SOLUTION: It is a muffling fluid pipe devised to form a cavity part between an outer surface of a fluid pipe 1 and an inner surface of a sheath pipe 2 when protruded parts 3 are formed on an outer peripheral surface of the fluid pipe 1 and it is inserted in the inner surface of the sheath pipe 2.  Additionally, it is the muffling fluid pipe constituted by providing a plural number of the protruded parts of the outer peripheral surface of the fluid pipe 1 along overall length in the axial direction, or more than one of the protruded parts 3 spirally by rod type or pipe type members along the outer peripheral surface of the fluid pipe 1, or a large number of the shapes of the protruded parts of the outer peripheral surface of the fluid pipe 1 and semispherical projections on the outer peripheral surface of the fluid pipe 1, or planting fibric hairs irregularly as the protruded parts 3 of the outer peripheral surface of the fluid pipe.  Consequently, as the protruded parts are interposed between the outer surface of the fluid pipe and the inner surface of the sheath pipe at the time of inserting the fluid pipe in the sheath pipe, large sliding resistance rarely works, and it is possible to carry out this insertion work smoothly and in a short period of time. As a cavity is formed between the outer surface of the fluid pipe and the inner surface of the sheath pipe, it is possible to improve a muffling effect against sound generated by a water hammer phenomenon.
