摘要

A safety device (1) for pipelines, comprising: - a rupture disc (2) shaped so as to be arranged along a pipeline (T), transversely thereto, and having a rupture portion (3) dimensioned so as to occlude said pipeline (T) and wherein a number of frangible lines (3') are defined and in turn define a plurality of petals (3"), wherein said frangible lines (3') are dimensioned so as to split open, in a discharge state of said device (1), and said petals (3") are suitable for opening, along said frangible lines (3'), so as to define a discharge section (S) for passage of said fluid coming from said pipeline (T), comprising a support (6) having a central opening (6') delimited by a number of sides (6") at least equal to the number of petals (3") and at least partly facing said rupture disc (2);said support (6) being suitable for installation in proximity to said rupture disc (2), so that each one of said petals (3") is apt for abutting, in said discharge state of said device (1), against a respective side (6") of said central opening (6').
