摘要： The invention concerns a method for the continuous production of a flexible tube body from two stapled wires (9, 10) individually bent in bending means (7, 8), three stitches, unsupported by a mandrel, and such that the wires (9, 10) remain constantly in contact so as to optimise their resistance to external pressure. The bending means (7, 8) can be arranged with respect to each other without affecting the bending adjustment. The method consists in stapling the two spirals by elastically deforming the turns so that one crosses the other to cause the wires to overlap partially. The invention also concerns an equipment for producing such a flexible tube body.

摘要： Procédé d'élaboration de fils d'acier destinés à la fabrication de conduites flexibles, fils d'acier obtenus par ce procédé et conduites flexibles renforcées par de tels fils. Il est caractérisé en ce que pour un taux d'écrouissage donné du fil initial, on réalise un traitement thermique dans des conditions de durée et de température telles que le fil d'acier obtenu après traitement présente une résistance mécanique à la rupture (Rm) supérieure à 850 MPa et une structure ayant peu de ferrite libre. Application notamment à la fabrication de fils d'acier compatibles avec l'H2S.

摘要： A method for making steel wires, wherein an elongate shaped wire is produced by rolling or drawing steel consisting of 0.05-0.8 % C, 0.4-1.5 % Mn, 0-2.5 % Cr, 0.1-0.6 % Si, 0-1 % Mo, no more than 0.25 % Ni, and no more than 0.02 % S and P, and a first heat treatment is performed on the shaped wire, including at least one step of quenching under predetermined conditions to achieve an HRC hardness of at least 32, a predominantly martensitic and bainitic steel structure and a small amount of ferrite. A shaped wire and a flexible tube for conveying an H2S-containing effluent are disclosed.

摘要： The method is characterized in that, for a given strain-hardening in the initial wire, heat treatment is carried out for a time and at a temperature such that the resulting steel wire has a mechanical breaking strength (Rm) greater than 850 MPa and a structure with a low free ferrite content. The method is useful in particular for manufacturing H2S-compatible steel wires.

摘要： A flexible tubular pipe (1) comprises, from the inside outwards, an inner sealing tube or sleeve (3) and an armouring consisting of a plurality of armouring webs. The armouring comprises a first armouring web (4) supporting the inner sealing tube or sleeve (3) and consisting of a plurality of armoured folded-seam strips (10) lying at an angle A1 of less than 80° in relation to the axis (2) of the flexible tubular pipe (1); and a set of armouring webs (5) placed on the outside of said first armouring web (4) and comprising at least one armouring web. The strips (10A) of said assembly have non-folded seams and are arranged in such a way that together, their angles complement angle A1 and a balanced flexible tubular pipe can be achieved.
