Embodiment Construction

[0035] According to a first embodiment shown in FIGS. 1 to 3 , a ring 2 for visually determining the crimped state of a joint 3 of a pipe 4 comprises an annular portion 5 provided on one edge thereof The notch 6 of the opening. Thus, the annular portion 5 presents a serration visible to the operator before crimping.

[0036] The ring 2 comprises a plurality of fins 7, the first ends 8 of which are connected to the annular part 5 at a distance from the joint and the second ends 9 of which are close to the joint body. Thus, during crimping, the crimping tool bears at the first end 8 of the fins 7, ie at the junction with the ring portion 5, and displaces the fins 7 and deforms the ring, the fins 7 Displaced against the body of the joint, at least partially closing the notch 6 facing it.

[0037] The second end 9 of the fin has a chamfer 10 which facilitates the displacement of the fin in a given direction, in particular in the direction of the notch 6 .

[0038] The ring 2 in...

Abstract

The ring (2) has an annular portion (5) presenting recesses (6) revealing the body of a coupling, and fins (7) situated facing the recesses. Each fin has an end (8) connected to the portion and situated at distance from the coupling, and an end (9) situated near the body so that the fin is displaced by a crimping tool during the coupling crimping operation in a manner to partially close off the recesses. An independent claim is also included for a crimped coupling for a tube has a ring.

Description

technical field [0001] The present invention relates to a ring for visually determining the state of a crimp and for a pipe joint. Background technique [0002] When installing a pipe network, the fitter makes an assembly in several stages, especially including pipes and fittings, assembles a pipe and a fitting together one by one, and then crimps them. , the fittings are crimped onto the ends of the pipes to ensure the durable mechanical integrity of the installed equipment and to guarantee its seal. [0003] In order to ensure that the installed equipment is durable and leak-free, all joints need to be crimped. Various solutions have been devised so that the user can verify that all connectors have been crimped. [0004] In particular, a method has been conceived in which a leak is generated at the joint until the joint has been crimped. This method allows the operator to detect uncrimped joints by applying pressure to the installation equipment and then identifying lea...
