Ring Body, Pipe Fitting, And Method For Joining Pipes

Abstract: A ring body 31, provided in a pipe fitting 1 in which an insertion port projecting portion 15 engages with a locking ring 8 from the rear side of a reception port 3, in a direction A separating from an insertion port 5, thereby making it possible to prevent the insertion port 5 separating from the reception port 3, includes a main body portion 32 provided in the pipe fitting 1 by being inserted between the inner circumferential surface of the reception port 3 and the outer circumferential surface of the insertion port 5, and a displacement stopping member 33 which prevents the main body portion 32 being displaced toward the open end side of the reception port 3, wherein the main body portion 32 reduces displacement, in the pipe radial direction, between the pipe axis of a first pipe 4 and the pipe axis of a second pipe 2 by moving the insertion port 5 in the pipe radial direction relative to the reception port 3.
