摘要:
Pressure vessel (1) with a gas-impermeable liner (2) and a reinforcing layer (4) in composite material formed externally around the impermeable liner (2), as well as at least one boss (5) coupled to the impermeable liner (2) and to the reinforcing layer (4), wherein between the impermeable liner (2) and the boss (5) a polymeric sealing mass (7) is arranged bound to both the impermeable liner (2) and to the boss (5) by means of in situ cross-linking of the sealing mass (7).
摘要:
A gas cylinder (1) comprising a cylinder body (2), a supporting part (11) with one or more resting portions (12) protruding towards a lower side (7) of the cylinder (1), a protection ring (13) manufactured separately and then mounted to the supporting part (11) and having an annular slot (14) which accommodates said one or more resting portions (12) and a resting surface (15) facing the lower side (7) and free from metal edges.
摘要:
A method for making a gas-tight container (1) in elastomeric material comprises: providing two or more separate elastomeric portions (2, 3), cleaning and/or roughening the gluing surfaces (6) of the gluing edges (5), applying an adhesive (7) onto the previously cleaned, degreased and/or roughened gluing surfaces (6), assembling the portions (2, 3) to form the container (1) and inserting between the gluing surfaces (6) a raw elastomeric tape (8) not yet cured, applying a cold pressure on the overlapped gluing edges (5), heating the overlapped gluing edges (5) to thermally activate the curing of the raw tape (8), cooling the gluing areas.
摘要:
A composite-material pressure vessel (1) has a wall (4) with a reinforcing layer (11) containing one or more reinforcing fibres, wherein the reinforcing layer is an electrical conductor, wherein the wall (4) forms an electrical capacitor (13) having a first plate formed of the reinforcing layer (11), a second plate formed of an electrically conductive layer (15) overlapping the dielectric layer (11), a dielectric layer (14) interposed between the reinforcing layer (11) and the electrically conductive layer (15), as well as electrical terminals (19, 20) connected to the first and the second plates. The vessel control method and system perform electrical tests on the capacitor to derive information about the wall (4) structural condition.
摘要:
A gas cylinder (1) comprising a cylinder body (2) with a tubular wall (5) having at least a first tubular portion (11) that is enlarged, and at least a second tubular portion (12) that is adjacent and narrowed relative to the first tubular portion (11).
摘要:
Method for generating tracing information for solid objects made from metal, synthetic or natural material (2), manufactured through the steps of providing an unrefined piece (3); subjecting the unrefined piece (3) to a plurality of transformation steps (5,6,7,8,9,11,14,17,18,22) so as to obtain the solid object (2) with the desired shape and material characteristics, wherein said transformation steps (5,6,7,8,9,11,14,17,18,22) comprise one or more heat treatment steps (5,6) such as to modify the mechanical characteristics of the piece (3) and/or one or more deformation steps (7,8,9,11,14,17,22) that modify the shape of the piece (3), subjecting the unrefined piece (3) or the solid object (2) obtained from it to at least one control step, wherein the method comprises the steps of: - equipping the unrefined piece (3), before the transformation steps, with a permanent individual marking (19) having an encoding field (39) with areas in bas-relief (42) in said unrefined piece (3), that comprises an identification code (20) of the single piece (3) and that permanently identifies the single unrefined piece (3) and the single solid object (2) obtained from it during manufacture, reading the individual marking (19) applied to the unrefined piece (3) and storing the identification code (20) read in a database (21).
