Periodic structure damping for pipelines and processing method

The invention discloses periodic structure damping for pipelines and a processing method and relates to a ship pipeline noise reduction method. Damping materials A (2) and damping materials B (3) are circularly arranged on the outer surface of a pipeline (1) at intervals and are annularly seamlessly attached to the outer surface of the pipeline (1) at intervals or helically seamlessly attached to the outer surface of the pipeline (1) in a spring shape to obtain the periodic structure damping of the pipeline. By adding two different damping materials, better damping effect is achieved. The periodic structure damping is widely applied to damping and noise reduction of various ship pipelines, only specifications and construction sequences of the materials are required to be changed, modification of original construction process is omitted, and the periodic structure damping has the advantages of simplicity in process, and high operability.
