Abstract

A pipe support for dampening acoustic propagation from a pipeline is provided. The pipe support can include a support base and a movable base spatially arranged from the support base. One or more fasteners can be disposed through the movable base to the support base, thereby connecting the movable base to the support base. One or more acoustic isolators can be disposed between an upper surface of the support base and a lower surface of the movable base.

Claims

1. An apparatus for dampening acoustic propagation from a pipe to a support structure, comprising:

at least one support base;

at least one movable base, wherein the movable base is spatially arranged from the support base;

one or more fasteners at least partially disposed through each of the support base and the movable base thereby connecting the support base and the movable base; and

one or more acoustic isolators disposed between the support base and the movable base, wherein each acoustic isolator comprises one or more heat resistant materials and one or more vibration absorbing materials, wherein the one or more heat resistant materials comprise fiber reinforced calcium silicate and the one or more vibration absorbing materials comprise one or more plastics, one or more elastomers, or a combination thereof.

2. The apparatus of claim 1, further comprising a clamp adapted for supporting one or more members.

3. The apparatus of claim 2, wherein the member is a pipeline.

4. The apparatus of claim 1, wherein the support base is a substantially flat, metallic plate.

5. The apparatus of claim 1, wherein the support base is a metallic plate fabricated from one or more metal alloys selected from the group consisting of ferrous alloys, galvanized ferrous alloys, and non-ferrous alloys.

6. The apparatus of claim 1, wherein the movable base is a substantially flat, metallic plate.

7. The apparatus of claim 1, wherein the movable base is a metallic component fabricated from one or more metal alloys selected from the group consisting of ferrous alloys, galvanized ferrous alloys, and non-ferrous alloys.

8. The apparatus of claim 1, wherein each fastener comprises one or more studs, carriage bolts, sections of all-thread, or any combination thereof.

9. The apparatus of claim 1, wherein the one or more heat resistant materials are disposed proximate the one or more vibration absorbing materials.

10. The apparatus of claim 9, wherein the one or more heat resistant materials have a bore, notch, or channel formed therethrough for receiving one or more of the fasteners therethrough.

11. The apparatus of claim 9, wherein the one or more heat resistant materials are disposed proximate to the one or more fasteners.

12. A system for dampening acoustic propagation from a pipe to a support structure comprising:

a support base;

a movable base, wherein the movable base is spatially arranged from the support base;

a fastener at least partially disposed through each of the support base and the movable base thereby connecting the support base and the movable base;

one or more acoustic isolators disposed between the support base and the movable base, wherein each acoustic isolator comprises one or more heat resistant materials and one or more vibration absorbing materials, wherein the one or more heat resistant materials comprise fiber reinforced calcium silicate and the one or more vibration absorbing materials comprise one or more plastics, one or more elastomers, or a combination thereof;

a clamp adapted to retain a moving member; and

a support member disposed on a first surface of the movable base at a first end thereof, and disposed on the clamp at a second end thereof, wherein the support member is substantially perpendicular to the first surface of the movable base.

13. The system of claim 12, wherein the moving member comprises a pipeline, a structural member, a support member, a rotating member, an oscillating member, a vibrating member, or any combination thereof.

14. The system of claim 12, wherein the one or more heat resistant materials are disposed proximate the one or more vibration absorbing materials.

15. The system of claim 14, wherein the one or more heat resistant materials have a bore, notch, or channel formed therethrough for receiving the one or more of the fasteners therethrough.

16. The system of claim 14, wherein the one or more heat resistant materials are disposed proximate to the one or more fasteners.

17. A supported pipe, comprising:

at least one pipe section;

at least one support base;

at least one movable base, wherein the movable base is spatially arranged from the support base and the pipe section;

one or more fasteners at least partially disposed through each of the support base and the movable base thereby connecting the support base and the movable base; and

one or more acoustic isolators disposed between the support base and the movable base, wherein each acoustic isolator comprises one or more heat resistant materials and one or more vibration absorbing materials, wherein the one or more heat resistant materials comprise fiber reinforced calcium silicate and the one or more vibration absorbing materials comprise one or more plastics, one or more elastomers, or a combination thereof.

18. The supported pipe system of claim 17, further comprising:

at least one clamp adapted to retain the pipe section; and

a support member disposed on a first surface of the movable base at a first end thereof, and disposed on the clamp at a second end thereof, wherein the support member is substantially perpendicular to the first surface of the movable base.

19. The apparatus of claim 17, wherein the one or more heat resistant materials are disposed proximate the one or more vibration absorbing materials.

20. The apparatus of claim 19, wherein the one or more heat resistant materials are disposed about the one or more fasteners.

21. An apparatus for dampening acoustic propagation from a pipe to a support structure, comprising:

a support base;

a movable base;

an acoustic isolator disposed between the support base and the movable base, wherein the acoustic isolator comprises one or more heat resistant materials and a vibration absorbing material, wherein the one or more heat resistant materials comprise fiber reinforced calcium silicate, wherein the vibration absorbing material comprises one or more plastics, one or more elastomers, or any combination thereof, and wherein the one or more heat resistant materials are independent from the vibration absorbing material; and

a fastener connected to the support base and the moveable base.

22. The apparatus of claim 21, wherein the one or more plastics are in the form of shredded plastic, fibrous plastic, or a combination thereof.

23. The apparatus of claim 21, wherein the fastener extends through the acoustic isolator.

24. The apparatus of claim 21, wherein the fastener extends through at least one of the one or more heat resistant materials.
