METAL BELLOWS TUBE, METHOD OF PRODUCING THE SAME, AND FLEXIBLE TUBE FOR HIGH-PRESSURE FLUID
The sectional shapes of a ridge 2 and a valley 3 in a bellows-shaped tube wall 1 of a metal bellows tube are made to be V-shaped. As a result, a metal bellows tube with significantly improved bending fatigue resistance compared to conventional ones can be provided. In addition, by this metal bellows...

| description | The sectional shapes of a ridge 2 and a valley 3 in a bellows-shaped tube wall 1 of a metal bellows tube are made to be V-shaped. As a result, a metal bellows tube with significantly improved bending fatigue resistance compared to conventional ones can be provided. In addition, by this metal bellows tube and a tubular metal braid covering the outside of the tube, a flexible tube for a high-pressure fluid of the present invention can be constituted. Consequently, a high--pressure fluid exceeding 20 MPa, particularly even a superhigh-pressure fluid of 70 MPa, can be transferred safely without transmitting the molecules of the fluid.
L'invention concerne des sections transversales de coude (2) et de creux (3) de paroi de tube du type soufflet (1), de tube pour soufflet en métal, en forme de V. Il s'agit de tube pour soufflet en métal ayant une résistance améliorée à la fatigue de courbure, par rapport aux produits classiques. On décrit un tube flexible pour fluide haute pression structuré à partir du tube pour soufflet en métal et un corps métallique maillé de type tubulaire recouvrant l'extérieur du tube pour soufflet. Le produit considéré permet d'acheminer en sécurité un fluide haute pression, à une pression dépassant 20 Mpa, et en particulier un fluide à très haute pression, à une pression de 70 Mpa, sans perméation de molécules de fluide dans le tube. |
