FLEXIBLE PIPE FITTING WITH TIE-BOLT

摘要

PROBLEM TO BE SOLVED: To provide a flexible pipe fitting capable of restricting the expansion of a joint automatically in compliance with the change of the load and also releasing the restriction. SOLUTION: A stopper 28 equipped with a resilient member having a tie bolt inserting hole is arranged so that the wall surface of the tie bolt inserting hole is in pressure contact with the peripheral surface of a tie bolt 27 in the condition that the resilient member is compressed and is attached to the tie bolt 27 on the outside about the tie bolt axial direction of the tie bolt mounting part 25 of a pipe fitting 20, and the tie bolt 27 is formed so that a distanceαis reserved such as to admit movement of the stopper 28 between the outer edge of the stopper 28 and the nut 30 mounting position of the tie bolt terminating part.
