PIPE FITTING AND PIPE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a pipe fitting embodied in a simple constitution and favorable in terms of cost and provide a pipe structure using it capable of coupling paper tubes simply and safely. SOLUTION: The pipe fitting and the pipe structure is composed of a body 1 consisting of a regular hexahedron and at least one piece member K1-K4installed on the body 1 and each having a projection Ktprotruding perpendicularly to the surface of the body 1, and the end of a coupling pipe P is is coupled with the projection Ktin such a way that the inner surface of the coupling pipe P is in contact with the projection Kt.
