A plurality of fasteners secured through fastener holes in the plates to connect the plates together. A masterlink is used to adjust the plates to various diameters of the process pipe. A safety cage can be connected to or over the standoff ring encircling the process pipe. ## Claims ### Claim 1 A standoff ring for temperature transfer to a process pipe, the standoff ring comprising: a. a plurality of single ring plates, each single ring plate having a plurality of single ring plate fastener holes; b. a plurality of double plate ring plates, each double plate ring plate having a first plate and a second plate, the first plate and the second plate having identical sizes and each first plate and second plate having a pair of aligned fastener holes, the single ring plates alternating with the double plate ring plates to form the standoff ring; c. at least one adjustable masterlink fastened between a pair of aligned double plate ring plates, wherein the adjustable masterlink comprises a plurality of alignment features allowing for adjustment of a size of the standoff ring, and further wherein each alignment feature comprises an alignment hole; d. a plurality of fasteners for fastening into the fastener holes, wherein each single ring plate connects between the first plate and the second plate of the double plate ring plates, the fastener holes of the three plates are aligned, and one of the plurality of fasteners engages the aligned fastener holes of the three plates simultaneously; and wherein each alignment feature mechanically interacts with a double plate ring plate of the plurality of double plate ring plates, mechanically interacts with a single ring plate of the plurality of single ring plates, or mechanically interacts with a fastener of the plurality of fasteners, further wherein each double plate ring plate of the plurality of double plate ring plates and each single ring plate of the plurality of single ring plates have a substantially identical shape. ### Claim 2 (depends on 1) The standoff ring of claim 1, wherein the at least one adjustable masterlink is a turnbuckle. ### Claim 3 (depends on 1) The standoff ring of claim 1, wherein each plate is solid 100 percent aluminum excluding the fastener holes. ### Claim 4 (depends on 1) The standoff ring of claim 1, wherein the fastener holes have a diameter from ¼ of an inch to 2 inches. ### Claim 5 (depends on 1) The standoff ring of claim 1, wherein the identical shape is selected from the group: rectangular, elliptical, triangular, or square. ### Claim 6 (depends on 1) The standoff ring of claim 1, wherein the plurality of single ring plates have a different length than the plurality of double plate ring plates. ### Claim 7 (depends on 1) The standoff ring of claim 1, wherein the plurality of single ring plates and the plurality of double plate ring plates have identical sizes. ### Claim 8 (depends on 1) The standoff ring of claim 1, wherein each of the plurality of fasteners is: a pin, a nut and bolt assembly, a removable pin with detent, a rivet, or combinations thereof. ### Claim 9 (depends on 1) The standoff ring of claim 1, further comprising a safety cage connecting to and extending from the standoff ring, wherein the safety cage encircles the process pipe providing a safety zone between users proximate the process pipe. ### Claim 10 (depends on 9) The standoff ring of claim 9, further comprising an aligned attaching hole for each double plate ring plate and each single ring plate, wherein the aligned attaching hole penetrates both plates of each double plate ring plate for securing the safety cage to the standoff ring. ### Claim 11 A standoff ring for temperature transfer to a process pipe, the standoff ring comprising: a. a plurality of single ring plates, each single ring plate having a pair of opposing single ring plate fastener holes, each single ring plate having a contact point for engaging a process pipe, the single ring plates each having identical sizes; b. an adjustable masterlink fastened between a pair of single ring plates, wherein the adjustable masterlink comprises a plurality of alignment features allowing for adjustment of a size of the standoff ring, and further wherein each alignment feature comprises an alignment hole; c. a plurality of fasteners for connecting pairs of single ring plates together, wherein each fastener of the plurality of fasteners engages at least two single ring plate fastener holes; and wherein each alignment feature mechanically interacts with a single ring plate of the plurality of single ring plates or mechanically interacts with a fastener of the plurality of fasteners, further wherein each single ring plate of the plurality of single ring plates is triangular or elliptical. ### Claim 12 (depends on 11) The standoff ring of claim 11, wherein each contact point has a blunt end. ### Claim 13 (depends on 11) The standoff ring of claim 11, further comprising a safety cage connecting to and extending from the standoff ring, wherein the safety cage encircles the process pipe providing a safety zone between users proximate the process pipe.
