General Information:
A compliment to cold insulated supports, high temperature supports were developed to take advantage of many of the cold insulated support features over standard direct contact devices such as welded or clamp-on supports. The qualified service temperature is -10 º F (-23 º C) to 1200 º F (650 º C), and to 1800 º F (983 º C )for some special applications. These 'hot' supports serve the following benefits -

• Heat conservation.
• Reduces localized stresses.
• Prevents deterioration of the piping insulation.
• Preserves the process temperature of the fluid in the pipe.
• Prevents the heating of the supporting structure.
• Eliminates the welding of high cost alloy supports to alloy piping.
• Eliminates the need for welding pipe supports in pipe fabrication yards.
• Reduces installation cost of piping insulation by eliminating special insulation transition cutouts.

Hot Product Lines:

• Pre-insulated pipe shoes
• Anchors and Guides
• Isolation blocks
• Micarta blocks, Sleeves and washers
• Calcium silicate insulation
• Foam glass insulation
• Mas Coat - Insulation Paint for Personnel Protection.

Features and Quality:

• Latest technology, materials and designs are used.
• Insulation is matched to the thickness and layering of process line insulation per ASTM C585 to insure proper field fit.
• Multilayer insulation capable.
• Custom designs available.
• Eliminates welding to pipe and expensive, cumbersome post weld heat treatment process.
• Eliminates galvanic corrosion problems between pipe and support material due to dissimilar materials.
• Saves cost through energy savings.
• Saves cost by eliminating extra installation steps.
• Each unit is individually bagged to protect against damage during shipping and storage.
• Each unit is shipped completely assembled and ready for installation.
• Reduces piping insulation breaches which are source of corrosion.

Support Designs:

Design	Drawing	Description
Resting	Available soon	Insulated supports that restrain the pipe vertically but allow axial and lateral movements. Some of Rilco's designs, such as the HS-1000 and HS-2000 have high density calcium silicate inserts which insulate the pipe while resisting the vertical and clamping forces of the support. Low density materials, such as calcium silicate insulation are joined with the high density inserts to create a section of insulation to be installed in conjunction with the pipe installed.
Guided	Available soon	Insulated supports that restrain the pipe vertically and laterally but allow axial movement. Guide clips or vertical guide members are provided with these designs, which are attached to the supporting structure and restrain the lateral movement of the support. In addition to the high density inserts to restrain the vertical loads for resting designs, guided designs also have inserts to restrain the lateral loads as well. Some of these designs include Rilco's HG-3000 and HG-4000
Anchor	Available soon	Insulated supports that restrain the pipe vertically, laterally and axially. In addition to guide clips to prevent lateral movement, thrust rings matching the pipe material are welded to the pipe which transfer the axial load to the support insulation, then to the support housing which in turn tranfers the load to the supporting structure. Some typical Rilco anchors are HA-4000 and HA-4100.
Clamp Hanger	Available soon	Insulated supports that restrain the pipe vertically by using a pipe clamp which clamps the insulated pipe. In other words, the pipe is supported by a clamp and the insulation is between the clamp and the pipe. Typical material for the insulation is low or high density calcium silicate. Rilco's most commonly sold models is the HH-3100.

Support Components:

Type	Photo	Description
High density calcium silicate inserts	Available soon	A typical insulation material for high temperature. Rilco has tested this material at the required temperature to determine allowable design stresses. Rilco stocks a variety of densities of calcium silicate material for different loading conditions.
Low density insulating materials	Available soon	If you prefer low density insulating materials to high density calcium silicate, Rilco can provide perlite or foam glass.
Water repellant	Available soon	To protect the insulating materials from water, the insulation section is treated with Rilco MP-11 water repellant. While this is a preventative measure, the support should be covered with plastic or other means if the support is to remain exposed for an extended period of time.
Outer sheet metal jacket	Available soon	A standard feature on most Rilco designs. This is an outer metal jacket, similar to the protective jacket on the line-insulation, wrapped on the outside of the vapor barrier and the insulation section. This jacket should be overlapped with line insulation jacket during installation. Once installed, the insulation section of the support will appear as an integral part of the insulation construction.
Steel housing with base components	Available soon	To support the insulation assembly, many of Rilco designs are supplied with a heavy fabricated steel outer saddle with a base. Depending upon the application, the steel assembly is designed to provide adequate support for the insulation section while properly transferring the loads being restrained to the supporting structure.
