Abstract
Abstract A pipe support for high temperature, thin-walled piping runs such as those used in nuclear systems. A section of the pipe to be supported is encircled by a tubular inner member comprised of two walls with an annular space therebetween. Compacted load-bearing thermal insulation is encapsulated within the annular space, and the inner member is clamped to the pipe by a constant clamping force split-ring clamp. The clamp may be connected to pipe hangers which provide desired support for the pipe.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
A support system comprising: a thin-walled pipe containing a liquid therein at an elevated temperature; a tubular metallic inner member comprising a tubular inside wall and a tubular outside wall, said inside wall and said outside wall forming an annular space therebetween, said inside wall having a diameter substantially equal to an outside radial diameter of said pipe, said inner member radially encircling and contacting said pipe; thermal insulating means located within said annular space, said thermal insulating means being encapsulated within said inner member and comprising compacted load-bearing thermal insulation; and means for clamping said inner member to said pipe, said thermal insulating means minimizing the amount of heat transferred from said pipe to said clamping means.
Claim 2
Dependent Claim
118 words
A support system comprising: a thin-walled pipe containing a liquid therein at an elevated temperature; a tubular metallic inner member comprising a tubular inside wall and a tubular outside wall, said inside wall and said outside wall forming an annular space therebetween, said inside wall having a diameter substantially equal to an outside radial diameter of said pipe, said inner member radially encircling and contacting said pipe; thermal insulating means located within said annular space, said thermal insulating means being encapsulated within said inner member and comprising compacted load-bearing thermal insulation; and means for clamping said inner member to said pipe, said thermal insulating means minimizing the amount of heat transferred from said pipe to said clamping means.
Claim 3
Dependent Claim
21 words
The system according to claim 1 wherein said insulation comprises a compacted mixture of diatomaceous silica, asbestos fiber, and inorganic binders.
Claim 4
Dependent Claim
15 words
The system according to claim 1 wherein said means for clamping comprises a split-ring clamp.
Claim 5
Dependent Claim
22 words
The system according to claim 3 wherein said clamp includes means for asserting a substantially constant clamping force on said inner member.
Claim 6
Dependent Claim
20 words
The system according to claim 3 wherein said clamp includes means for compensating for any radial expansion of said pipe.
Claim 7
Dependent Claim
12 words
The system according to claim 1 wherein said inner member is cylindrical.
Claim 8
Dependent Claim
25 words
The system according to claim 1 wherein means for maintaining a substantially constant spatial position of said system is connected to said means for clamping.
