Abstract:
1. An elongated hose with corrugated metal tube for conveying highly permeable fluid comprising: an inner layer comprising a corrugated metal tube having corrugation hills and valleys, wherein the corrugation hills and valleys are annular; an outer layer circumscribing a radial outer side of the inner layer; a reinforced layer having reinforcing filament members and included in the outer layer, the reinforcing filament members being braided at a low braid angle, 40 degrees or lower, with respect to an axis, the reinforced layer thereby generating sufficient resistance to pressure exerted repeatedly by fluid conveyed by the hose; a pipe-shaped connecting part formed with a fit-engagement groove on an outer peripheral surface thereof, the connecting part being inserted in a straight-walled portion formed on an axial end side of the corrugated metal tube, the straight-walled portion of the corrugated metal tube extending beyond a fit-engagement groove; a socket fitting having a radially inwardly directed collar-like portion, the socket fitting being securely compressed on an outer surface of an end portion of the outer layer; and wherein an inner end portion of the collar-like portion is fitted in and engaged with the fit-engagement groove of the connecting part while clamping the straight-walled portion.
