Method for making a detection device for detecting the position of a movable rod of a pneumatic actuator and detection device obtainable with that method
A method for making a detection device (2) for detecting a position of a movable rod (4) of a pneumatic actuator (1) comprises a step of taking a first body (17) comprising a connecting portion (19), a supporting portion (20), an electrical connector (21), a detection sensor (15) for detecting a magnetic field and electrical connecting means (22). The method then comprises a step of taking a second body (18) comprising a housing (14) in which the supporting portion (20) can be inserted, a step of inserting the supporting portion (20) and the detection sensor (15) positioned on it in the housing (14) and a step of irremovably constraining the first body (17) to the second body (18). The first body (17) and the second body (18) comprise, one at least one projecting element (25) and the other at least one corresponding hole (26); during the insertion step the projecting element (25) is inserted in the hole (26). During the constraining step the first body (17) is irremovably constrained to the second body (18) by plastically deforming the projecting element (25) to prevent it from being extracted from the hole (26) in which it is inserted.

A process for making heat exchanger tubes includes the operating steps of cutting a piece of sheet, subjecting the piece of sheet (3) to a forming step to obtain a plurality of first elements (8, 9) which mirror one another, and bending the piece of sheet (3) to create a tubular element (1) which has two flat walls (4) with the raised elements (8, 9) on them, the flat walls being opposite one another and joined by two connecting walls (5). The first raised elements (8) have an extended shape according to their main direction of extension. The forming step involves making one or more higher second raised elements (9).

Process for producing heat exchanger tubes and heat exchanger tubes
A process for making heat exchanger tubes comprises the operating steps of cutting a piece of sheet, subjecting the piece of sheet (3) to a forming step to obtain a plurality of first elements (8, 9) which mirror one another, and bending the piece of sheet (3) to create a tubular element (1) which has two flat walls (4) with the raised elements (8, 9) on them, the flat walls being opposite one another and joined by two connecting walls (5), and; the bending step substantially joining the lateral edges (7) to one another; and welding the lateral edges (7) to close the tubular element (1). The first raised elements (8) having an extended shape according to their main direction of extension. Those of the rows closest to the central axis (X) are made in such a way that their main direction of extension is set at an angle to the central axis (X) and to a direction perpendicular to it, while those of the rows closest to the lateral edges (7) are made in such a way that their main direction of extension is set at an angle to the central axis (X) and to a direction perpendicular to it, on the opposite side relative to the first raised elements (8) of the rows closest to the axis (X). The claims also relate to a tube obtained in this way.
