Vibration attenuation support for pipelines with thermal expansion movement

Abstract

Embodiments include an attenuation support to support or mitigate movement of an element, mainly a pipe of a pipeline, in which the movement comprises vibration and/or thermal expansion. The support can include damping elements, spacer elements, a housing housing the damping elements and the spacer elements, a rod extending through the housing, in which the damping elements and the spacer elements are intercalated with each other within the housing. The rod can be mounted with radial interference in relation to the damping elements. The damping elements can be hollow discs of elastomeric material, and the spacer elements can be hollow discs of rigid material. When thermal expansion movement of a pipe occurs, the rod moves in relation to the damping elements. When the dynamic movement occurs due to vibration of the pipe, friction between the rod and the damping elements deforms the latter, causing a hysteretic damping of the movement.
