Acoustic dampening pipe shoe
View Patent ↗Pipe shoe can include pipe retained by clamp attached to top plate. Acoustic isolation block is disposed for compression between top plate and bottom plate. Top plate is retained to bottom plate by stud(s) and nut(s). Flexible peripheral seal is disposed around acoustic isolation block between top and bottom plates. Pipe shoe can include thermal insulation and/or protective covering over any portion of pipe shoe and/or hot pipe.
1. A pipe shoe for dampening acoustic propagation from a hot insulated pipe comprising:
an acoustic isolation block disposed and compressed between opposing top and bottom plates, wherein the acoustic isolation block comprises fiber-reinforced calcium silicate;
at least one clamp connected to the top plate supporting a pipe;
at least one fastener retaining the top plate to the bottom plate and comprising a stud connected to the bottom plate extending through a bore in the acoustic isolation block and the top plate to a nut;
a flexible peripheral seal between the bottom and top plates around the acoustic isolation block;
thermal insulation over exposed surfaces of the pipe, the at least one clamp, the top plate, the seal, or a combination thereof; and
a protective covering over the thermal insulation.
2. The pipe shoe of claim 1 , wherein the acoustic isolation block comprises fiber-reinforced calcium silicate.
3. In a pipe support system comprising a hot insulated pipe supported on a pipe shoe comprising a pipe support member attaching the pipe to a base plate, the improvement comprising:
an acoustic isolation block disposed and compressed between the base plate of the pipe shoe and an opposing sub-base plate;
a flexible peripheral seal between the base and sub-base plates around the acoustic isolation block;
at least one fastener retaining the base plate to the sub-base plate;
thermal insulation over exposed surfaces of the pipe and pipe support member and one or a combination of the sub-base plate, the acoustic isolation block, the peripheral seal, or the base plate; and
a protective covering over the thermal insulation.
