Abstract: A damping device (1) for pipelines (2) includes a compression ring (3) with three ring segments (4) that can be positioned around a pipe (2). Each ring segment (4) forms a damper seat (8) that receives at least one damping element (9) made of elastomeric material intended to be radially compressed against an outer surface of the pipe (2). The damper seat (8) is in shape connection with the damping element (9) so as to prevent the damping element (9) from being released from the damper seat (8) in an axial direction and in a radial direction.

Abstract: A blower device includes a Coanda effect fluid flow amplifier having a suction opening, an outlet opening to provide an amplified fluid flow, an inner passage along an amplifier central axis passing through the suction opening and the outlet opening. An inlet conduit inputs pressurized fluid into the inner passage for drawing the ambient fluid from the suction opening to the outlet opening by Coanda effect, achieving amplified flow. A diffuser downstream of the amplifier includes diffuser side walls that delimit a diffuser inner side surface extending about a diffuser central axis arranged along the amplifier central axis and terminates with a first flow inlet open end facing the outlet opening, and an opposite second flow outlet open end delivers further amplified fluid flow. At least one side opening is upstream of the second flow outlet open end to allow additional ambient fluid to be sucked into the diffuser.

Abstract: A gas diffusion system configured to feed a gas stream, in particular a passivating gas stream, into an apparatus, in particular a decomposer, of a urea plant; the system extends along an axis and has a gas feed conduit having an outlet from which the gas flows substantially parallel to the axis, and a diffuser assembly configured to diffuse the gas supply from the conduit; the diffuser assembly is shaped so as to intercept the gas stream flowing axially from the outlet, and divert the gas stream substantially radially with respect to the axis and uniformly about the axis.

Abstract: An axial damper for elements having a cylindrical, rectangular or squared section, includes two identical fixing clamps, each fixing clamp including an upper part and a lower part connected to each other by a clamping device to be wound around the elements. At least two rafter-tie-rods are each connected at two ends thereof to the clamps. The rafter-tie-rods are placed equidistant from each other in the case of more than two rafter-tie-rods. The damper also includes two damping systems, each including two or more blocks of elastomeric material, with a pre-compressed elastic element interposed therebetween.
