Abstract
A generally tubular laminated acoustic damping pipe cover to be used on a water pipe to reduce the noise level of the pipe, having a sound insulation layer whose area density is 1.5-5.0 kg/m2 and a sound absorptive layer whose thickness is 4.0-10.0 mm, covered with a heat-contractile film which when heat treated will tighten the acoustic damping pipe cover on the water pipe but hold the pipe cover in a sliding fashion. The acoustic damping pipe cover is lightweight and easy to manipulate, and provides an excellent acoustic damping performance.
Claims6
A laminated tubular acoustic damping pipe cover to be used on a pipe, comprising:
- a sound insulation layer whose area density is 1.5-5.0 kg/m2;
- a sound absorptive layer whose thickness is 4.0-10.0 mm, which is held fixed relative to said sound insulation layer;
- and
- a loosely provided outermost heat-contractile cover layer,
- said heat-contractile cover layer to be heat treated so as to shrink and tighten but hold the acoustic damping pipe cover on the pipe in a sliding fashion.
