摘要:
The invention relates to composite hose, which is capable of being used without leakage, and which has a longer length and/or diameter than has been previously achievable. A composite hose comprises a tubular body of flexible material arranged between an inner and an outer helically wound wire. The hose further comprises an axial strengthening means adapted to reduce deformation of the tubular body when the tubular body is subjected to axial tension, the axial strengthening means being adapted to exert a radially inward force on at least part of the tubular body when axial strengthening means is subjected to axial tension. The hose can have length above 30 m and a diameter above 400 mm. A method of, and apparatus for, making the hose are also described, which involves the use of a non-metallic mandrel.

A flexible pipe body and method of producing a flexible pipe body are disclosed. The flexible pipe body includes a collapse resistant layer comprising a radially inner surface and a radially outer surface, the radially inner surface comprising, in cross section, a substantially flat portion and at least one cavity extending from the flat portion radially outwards, and the radially inner surface further comprising, in cross section, at least one aerodynamic feature extending from the flat portion for breaking up a boundary layer of fluid flowing along the flexible pipe body in use.

The present disclosure relates to an end fitting and method to install the end fitting to a flexible pipe. The method includes disposing a shell mandrel at a free end of the flexible pipe external to a jacket of the flexible pipe and performing a cutback of layers of the flexible pipe to expose an internal pressure sheath of the flexible pipe. An armor layer of the flexible pipe is radially outward from an axial direction of the flexible pipe. At least one internal pressure containment transition component and at least one internal pressure sheath seal are installed on the exposed free end of the flexible pipe. The end fitting is assembled such that the at least one internal pressure containment transition component and at least one seal are assembled with non-radial fasteners having a backward facing direction.

摘要:
On décrit comment un raccord de tuyau peut être fabriqué commodément par usinage au lieu de moulage, malgré ses formes compliquées et ses petites dimensions. Un modèle est créé, un programme d'usinage est défini, des vérifications sont faites et les résultats précédents sont entrés dans une machine-outil à commande numérique.
摘要:
A method of connecting a resin hose (1) to a metal pipe (4) comprising the steps of: forming a fluororubber coating layer (2) on an inner peripheral surface of the resin hose; forming a lubricating layer (3) of a fluorine-containing lubricant on an inner peripheral surface of the fluororubber coating layer (2); and inserting an end portion of the metal pipe (4) into an end portion of the resin hose (1) formed with the lubricating layer (3). Fluorine atoms in a fluororubber molecular skeleton are hydrogen-bonded to hydroxyl groups introduced in a metal of the metal pipe (4) and therefore the adhesion between the resin hose (1) and the metal pipe (4) is enhanced for improvement of the sealing property. Further, the lubricating layer (3) facilitates the insertion of the metal pipe (4) into the resin hose (1) for the connection therebetween.
摘要:
A flexible connector apparatus for decoupling vibrations, for example, along the components of an internal combustion engine exhaust system. The flexible connector apparatus is provided for connecting first and second components in the exhaust system, and includes a bellows for accommodating relative movement between the first and second components. The flexible connector apparatus includes an attachment construction which enables weldless, gasketless connection of the bellows to at least one of the first and second components. The flexible connector apparatus may include a liner tube structure having inlet and outlet liner tubes. An alternative construction incorporates a multi-ply bellows in the absence of a liner structure.
摘要:
A ferrule (10) comprises a cup of steel having a tubular wall (11) and end wall (13) which is divided into radially extending fingers (161, 162 ....) each of which terminates at a barb member (181, 182 ....) formed by deflecting a tapered end portion of the finger. The end wall fingers extend orthogonally to the longitudinal axis (12) of the tubular wall and the barb members are each inclined at an acute angle to the carrying fingers and axis such that when a tubular body, such as a braided or like textile sleeve, is received in the tubular wall and the end wall is swaged to cause the fingers to enter the body and lie flat against the tubular wall, the barbs are caused to penetrate the body and be flattened by the tubular wall to point in the direction towards the body end and inhibit its removal. The tubular wall may be circumferentially continuous (annular) or discontinuous (slit) and openable.
