Embodiment Construction
[0025] The invention relates to a damping sleeve used for vibration and noise reduction of metal pipelines and a cladding method.
[0026] The outer diameter of the metal pipeline is set as D, and the diameter of D can reach Φ30-Φ300mm.
[0027] combine Figure 1-2 , the damping sleeve 1 with a thickness of T is mostly semi-cylindrical and made of rubber material. The material is either neoprene, nitrile rubber, or polyurethane rubber, and an anti-aging agent is added to the rubber material.
[0028] The inner diameter of the multi-semi-cylindrical shape matches D, the expanded width of the multi-semi-cylindrical shape is ≥3лD / 4, and several cavity holes 2 are arranged on the outer surface of the damping sleeve, and several cavity holes 2 are arranged along the damping sleeve The axial direction of the pipe 1 is arranged in several rows, the distance between two adjacent cavity holes in each row is equal to K, and the distance between the cavity holes in adjacent rows is als...
