Abstract

A process to manufacture three-dimensional articles by press and/or thermo-forming a substantially flat web comprising a cellulose-based material is provided; the process includes: providing more than one flat web as a dry intermediate product with a density included between 50 and 250 Kg/m3, each dry intermediate product comprising the cellulose-based material in an amount between 40% and 95% by weight and a binder material between 5% and 50% by weight; making a predetermined number of through cuts through the dry intermediate product defining a plurality of interconnected portions; superimposing the flat webs one on the other to obtain a multi-layer stack of flat webs and positioning the multi-layer stack in a form-shaping tool; activating the form-shaping tool to thermoform a three-dimensional article, wherein the interconnected portions move with respect to each other during the press- and/or thermo-forming, superimpose each other and are then irremovably interconnected in the three-dimensional article.

a); and f) lowering into the wellbore (4) the first well tubular (6) and the second well tubular (7) welded together. Step e) comprises the operations of: providing at least one laser welding head (13), configured for directing a laser beam (LB) towards a circumferential working zone (WA) that includes an upper end portion of the first well tubular (6) and a lower end portion of the second well tubular (7), the at least one laser welding head (13) being displaceable around the circumferential working zone (WA) according to a respective trajectory of revolution; providing at least one induction-heating device (141, 142), which is displaceable substantially according to the trajectory of revolution of the at least one laser welding head (13), the at least one induction-heating device (141, 142) being set upstream, respectively downstream, of the at least one laser welding head (13), with reference to the direction of revolution (R) of the at least one laser welding head (13); causing revolution of the at least one laser welding head (13) and revolution of the at least one induction-heating device (141, 142), in such a way that: the laser beam (LB) progressively forms the circumferential weld bead (WL); and the at least one induction-heating device (141, 142) supplies heat to a corresponding part (PH1, PH2) of the circumferential working zone (WA), which comprises respective parts of said upper and lower end portions of the respective first and second well tubulars (6, 7), before the laser beam (LB) reaches said corresponding part (PH, PH2), respectively after the laser beam (LB) has reached said corresponding part (PH1, PH2).

Abstract

Described herein is a tubular apparatus for making rigid tubular structures, comprising a flexible cylindrical wall (11, 11') defining inside it a hollow passage (19), and suited for being wound, in particular on a spool, and continuously laid for use. According to the invention, said cylindrical wall (11, 11') comprises a fabric (12, 13, 15, 12', 13', 15') comprising inside it at least one gap (14;14'), which develops in the axial direction of said cylindrical wall (11, 11'), said fabric (12, 13, 15; 12', 13', 15') comprising means suitable for operating under traction (15, 15') when present within said at least one gap (14; 14') is a fluid (20), injected under pressure for stiffening the tubular apparatus (10; 10').
