FIXTURE OF INNER PIPE AT PIPE LINE PORT

摘要

PROBLEM TO BE SOLVED: To provide a fixture which can easily fix a plurality of corrugated inner pipes laid in a pipe line at the pipe ports. SOLUTION: A fixture 3 is composed of a plate 5 fixed to a pipe line port, and a cylindrical member 6A attached to an outer periphery of an inner pipe 2. Holes 7 for the insertion of the inner pipes 2 are formed on the plate 5 by the number of the inner pipes to be fixed. A thread projection is formed on an inner peripheral surface of the cylindrical member 6A so as to be screwed with a recession 12 of an outer peripheral surface of the inner pipe 2 formed with spiral corrugation. An outer diameter of the cylindrical member 6A is set larger than an inner diameter of the hole 7 on the plate 5. The cylindrical member 6A is screw-connected with the inner pipe 2 inserted into the hole 7 of the plate 5, at the inner side part and outer side part of the plate 5. The inner pipe 2 is fixed by sandwiching the plate 5 by means of the cylindrical member 6A.
