摘要:
A multilayer tube (10), particularly for industrial systems for the production and/or treatment of chemical compounds and the like, in fluid form, comprising a plurality of layers (11), of which at least one internal layer (12), which forms the duct for the fluid, an electrically conducting layer (13) which is external to the internal layer (12), and a protection and finishing layer (14) of the electrically conducting layer (13) which it covers, forming the outer surface (15) of the multilayer tube (10). The protection and finishing layer (14) has a matrix (16) made of electrically insulating material that is penetrated by electrically conducting bridges (17), the bridges (17) being discrete, mutually electrically insulated from the matrix (16) and scattered substantially uniformly within it. Furthermore, the bridges (17) are in electrical contact with the electrically conducting layer (13) and facing the external surface (15) so as to form an electrical connection between the electrically conducting layer (13) and the outside of the multilayer tube (10).
摘要:
The machine for producing vulcanized rubber tubes comprises two mutually opposite head sections (11,12), each having a base (13,29) that supports two spindles (17,30,31). At least a first one of the two head sections (11) has motorized spindles (17). A corresponding tubular core (41) is rotated constantly, during operation, between the mutually opposite spindles (17,30,31) of the two head sections (11,12) and is supported, along its span, by supporting elements (42) that are fixed to a supporting frame (43) interposed between the two head sections (11,12). The two motorized spindles (17) connected to the first head section (11) are each supported together with a respective drive unit (18) on a first slider (14) that is movably coupled to the corresponding base (13). The slider (14) is inclined with respect to a horizontal plane such that its upper part is exposed frontally to the operator.
