    摘要: The invention relates to an umbilical (2) comprising a center tube (4).
    The main technical feature of an umbilical (2) according to the invention is that said center tube (4) is a steel tube and that the cross section of said center tube (4) at the extremity of said umbilical (2) is made corrugated on a length that extends substantially from said extremity to a distance from said extremity so that fatigue strain on non corrugated parts of said steel tube is avoided when the extremity of said umbilical (2) is inserted into a bend stiffener (1).

    摘要: The invention relates to a fluid duct (10), especially for use in motor vehicles to feed liquid in order to wipe windows or headlights of said motor vehicle. Said fluid duct (10) comprises a flexible pipe (12) with at least one corrugated pipe section (22) and at least one plain pipe section (24) that adjoins the corrugated pipe section (22), at least one pipe joint (16, 20) with a pipe connecting section (26) which is inserted into a plain pipe section (24), and a support sleeve (36) for each pipe joint (16, 20). The support sleeve (36) surrounds the plain pipe section (24) receiving the pipe connecting section (26) and presses the plain pipe section (24) against the pipe connecting section (26).

    摘要: The invention relates to a refrigerant conduit for use in air-conditioning systems, especially automotive air-conditioning systems. Said conduit comprises a corrugated metal tube (1) having radially exterior corrugation peaks (2) and radially interior corrugation troughs (3). The aim of the invention is to optimize the mobility of the metal tube. For this purpose, the ratio of the outer diameter (Da) of the corrugation peaks (2) to the inner diameter (Di) of the corrugation troughs (3) is more than 1.3 and the metal tube has, at least in same areas, a wall thickness (Sa, Si) ranging from 0.10 to 0.25 mm.

    摘要: Cross sections of both a mountain (2) and a valley (3) of a bellows-like tube wall (1) of a metal bellows tube are made to a letter-V shape. This enables to provide a metal bellows tube with a much better bending fatigue resistance property than that available in conventional products. A flexible tube for a high-pressure fluid is structured from the metal bellows tube and a tube-like metal knitted body covering the outer side of the bellows tube. This makes it possible that a high-pressure fluid with a pressure exceeding 20 MPa can be, and particularly, even a very high-pressure fluid with a pressure of 70 MPa can be safely transported without allowing molecules of the fluid to permeate the tube.

    摘要: This invention concerns multilayer plastic tubing with a smooth inner tube (12) and a corrugated outer tube (14). The smooth inner tube (12) consists of a first plastic and the corrugated outer tube (14) consists of a second plastic which is foamed using a propellant. The wall thickness (D) of the corrugated outer tube (14) is at least 10 % of the average corrugation width (WB) of the corrugated outer tube (14). The inner tube (12) can be made of uniform plastic or of recycled material. The outer tube (14) can be made of recycled PE and/or PP and/or PVC.

    摘要: The invention relates to a system for stabilising the shape, and reinforcing and preventing shrinkage of cups of double-walled corrugated pipes in a plastic material, more particularly polyolefins and PVC, by drilling and subsequent injection into their closed annular ribs, which in this way also serve as forming moulds, of sufficiently fluid and preferably fast-setting materials, in quantities such as to fill the whole mould, capable after their solidification of withstanding external stresses mainly caused by shrinkage of the cup which tends to regain the position of molecular equilibrium, corresponding to its extrusion shape; these operations of drilling and injection being preferably performed during the phase of forming of the cup, therefore before the start of possible phases of shrinkage.
