Claim 5:
6. Process for capturing accidental pressurized fluid leaks from a broken pipeline, which uses a flexible piping according to claim 1, for redirecting the fluid flow towards the desired region or towards a storage tank, optionally provided with a pump (21) in order to create a depressurization of the flexible piping, wherein the following steps:
joining between them on a relatively short portion from the front ends (c) and from the rear ends (e) of the adjacent strips (A) that will form the piping, by joining the parts (a) with the parts (b) of the toothed zipper rails (7 and 8) and moving the sliders (9 and 10) on a conveniently selected distance along the rails (7 and 8) towards the limit stops (11 and 12) of the antagonistic zippers (B and C), by commands applied to the terminals (25 and 26), of the sliders (9 and 10);
assembling together by interconnecting and wrapping around a pipeline (20) connected on a storage tank or to a pump (21) one end (c) of the flexible strips (A) in front of which there are joined together in plane, so that, on this pipeline there are superimposed a number of 3 up to 5 networks of electrical heating resistances (3) provided in front of the short zippers (B), thereafter, in the condition in which the shape memory material inserts (18) are curved by commands applied to the terminals (4), and the magnetic inserts (16) positioned at this end (c) of the strips (A) are fixed on the pipeline (20), by applying a command to the terminals (25) there is commanded the movement of a slider (9) along the tooted rail (7) of the zippers (B) towards the limit stops (11), and subsequently, by the commands applied to the terminals (25) of all sliders (9), these are moved on a conveniently selected portion towards the limit stops (11);
applying voltages are applied to the terminals (4) of the networks of electrical heating resistances (3) for the heat shrinking and gradual molding of the layers (2) of heat shrinkable materials of the strips (A) and implicitly, for fluidization of the adhesive layers (15) provided to the inner side thereof, until obtaining a complete molding and a vulcanization of this end of the flexible piping to the body of the pipeline (20) connected to a tank or to a pump (21);
assembling together by interconnecting and wrapping around a broken pipeline (1) of the other end (e) of the flexible strips (A) in front of which they are joined in plane, so that, there are superimposed a number of 3 up to 5 networks of electrical heating resistances (3) provided in front of the long zippers (C), thereafter, in the condition in which the inserts (19) of shape memory materials are curved by commands applied to the terminals (4), and the magnetic inserts (17) positioned at this end (2) of the strips (A) are fixed on the pipeline (1), by applying a command to the terminals (26) of a slider (10), there is commanded the movement thereof along the toothed rails (8) of the short zippers (C) towards the limit stops (12);
applying voltages are applied to the terminals (4) of the networks of electrical heating resistances (3) for the heat shrinking and gradual molding of the layers (2) of heat shrinkable materials of the strips (A), and implicitly for the fluidization of adhesive layers (15) provided to the internal part thereof, up to obtaining a complete molding and a vulcanization of this end of the flexible piping on the body of the broken pipeline (1); and
commanding in a centralized manner the movement of all robotic closing sliders (9 and 10), along the toothed rails (7 and 8), up to the limit stops (11 and 12) for totally closing all the antagonistic zippers (B and C), longitudinally sealing the flexible piping and having the possibility of creating a controlled depressurization by means of the pump (21) or by means of the purges (23) provided with fast couples to which additional piping can be connected towards the storage tanks.
