Abstract
Abstract An anchor and insulation arrangement for a conduit or pipe employed in cryogenic conditions includes an outer housing for surrounding the conduit, the housing including longitudinally extending, spaced members secured thereto and extending inwardly thereof and reinforcing members secured to said housing adjacent the ends thereof. A cage arrangement is adapted to be secured to the pipe within the housing and includes end members with members extending longitudinally therebetween which are in spaced relation about the conduit. Rigid, cellular type material such as polyurethane preferably having a density in the range of about 4 to about 30 pounds per cubic foot, is formed in the housing and fills the space between the housing and the conduit, whereupon the housing and cage cooperate to act as an anchor to inhibit any relative movement between the conduit, the housing and cage, as well as providing an insulation arrangement. The rigid cellular type material includes annular projecting segments at each end to aid in inhibiting icing.

Total Claims: 19
Claim 1
Independent Claim
198 words
An anchor and insulation arrangement for a conduit including: a. a cage arrangement for securing to the conduit, said cage arrangement including: 1. annular end members secured transversely to the conduit; and 2. members, each including an opening therein, secured between said end members and extending therebetween in circumferentially spaced relation about the conduit; b. a short outer housing for surrounding the conduit; c. said outer housing including longitudinally extending, circumferentially spaced members secured to and extending inwardly of said housing, said longitudinally extending meMbers being radially spaced from said cage arrangement to form a void therebetween; d. means connected to the outer housing for anchoring the housing to a support; e. polyurethane surrounding the cage and conduit and filling the void between said cage arrangement and outer housing for insulation of the conduit; and f. said housing including inwardly extending reinforcing rings spaced from said longitudinally extending members on said housing, said reinforcing rings on said housing and said cage arrangement end members being positioned relative to each other to act in an opposing manner toward each other to inhibit movement of the conduit anchor and insulation arrangement due to end thrust in either longitudinal direction thereon.
Claim 2
Dependent Claim
198 words
An anchor and insulation arrangement for a conduit including: a. a cage arrangement for securing to the conduit, said cage arrangement including: 1. annular end members secured transversely to the conduit; and 2. members, each including an opening therein, secured between said end members and extending therebetween in circumferentially spaced relation about the conduit; b. a short outer housing for surrounding the conduit; c. said outer housing including longitudinally extending, circumferentially spaced members secured to and extending inwardly of said housing, said longitudinally extending meMbers being radially spaced from said cage arrangement to form a void therebetween; d. means connected to the outer housing for anchoring the housing to a support; e. polyurethane surrounding the cage and conduit and filling the void between said cage arrangement and outer housing for insulation of the conduit; and f. said housing including inwardly extending reinforcing rings spaced from said longitudinally extending members on said housing, said reinforcing rings on said housing and said cage arrangement end members being positioned relative to each other to act in an opposing manner toward each other to inhibit movement of the conduit anchor and insulation arrangement due to end thrust in either longitudinal direction thereon.
