Hot (Pyrogenic) Supports
PyroWrap
The PyroWrap pipe supports systems are manufactured to match the diameters of the Aspen Aerogels® Pyrogel® XT-E insulation thickness allowing for seamless transitions from the support structure to the line insulation and for the piping to be nested closer together throughout the system’s design. The Pyrogel® XT-E insulation is hydrophobic; however, it still allows water vapor to escape through the insulation, significantly reducing the onset of CUI (Corrosion Under Insulation) at the pipe support locations.
The graphic below indicates a diameter comparison of Pyrogel XTE insulation compared to several other materials. All four designs provide the same level of thermal protection.
The design of the Rilco PyroWrap system also permits for the modularization of the pipe. This feature provided the option for the supports along with the insulation to be pre-installed off-site, or at a safe location on-site. The system’s durability enables the pre-installed sections to be transported to the project site without damage.
Additionally, Rilco PyroWrap™ pipe supports are differentiated from alternatives by their hydrophobic properties throughout the entire matrix of insulation rather than merely on the surface level. The structural integrity of the system is unsurpassed due to the durability and resilience of the supports and insulation. PyroWrap™ supports are 50-75% thinner than systems with traditional hot insulation such as Calcium Silicate, making them lighter and, therefore, less costly to install. Furthermore, our supports are uniquely designed for each project and backed up with physical testing in order to ensure they perform for the life of a project.
Finally, one of the most essential benefits that the PyroWrap™ systems provide is the ability to support the pipe without sacrificing the dimensional and thermal insulation benefits of the Pyrogel XTE™ material. When the Pyrogel™ is backed by the Rilco support design and product expertise, the result is the highest quality pipe support for our clients.
Rilco PyroWrap Pipe Support systems are applicable for environments up to 1200 degrees F. The Pyrogel® XT-E Insulation material is used widely in refineries, petrochemical, and gas processing industries. It is up to 5 times better in regard to thermal performance than alternative insulation materials.
PyroWrap supports are 50-75% thinner than systems using traditional hot insulations such as Calcium Silicate, making them lighter, and therefore, less costly to install. The size reduction is largely due to the efficiency of the Pyrogel® XT-E insulation and the cutting edge design of the support structure.

Calium Silicate / Chilled Water
Rilco engineers and produces the traditional Calcium Silicate pre-insulated pipe supports. These supports can be stepped both radially and longitudinally to tie in with the same layering thickness as the line insulation to prevent straight heat path to the pipe.
Rilco manufactures two different designs of hot shoe designs including sleeve and bent ear.
Sleeve Design
The Rilco sleeve design is the modern approach to supporting piping which will soon become standard that all other pre-insulated supports are judged by. The sleeve design is referred to as such due to the unique use of steel tubes (sleeves) attached to both the upper and lower support components. The use of the Belleville washers included with the fasteners are the key to the effectiveness of the support design and require the “float” of the fastener within the upper sleeve to manage the expansion and/or contraction while maintaining proper clamping force on the pipe to prevent displacement between the process pipe and the pipe support. Rilco has performed manual calculations, FEA and thermal analysis, and physical testing on these style supports to have the confidence to say that Rilco can design supports that meet your loading, movement and heat loss requirements.
This Rilco standard design includes steel sleeves and Belleville washers. The washers, included in this sleeve design, are engineered to maintain a constant clamping force throughout the pipeline temperature range to accommodate the expansion and contraction of the process pipe.
Bent-Ear Design
The Rilco traditional design of bent ear which is the standard which is currently the accepted standard for the pre-insulated pipe support. This design relies on the elasticity of the formed ear section of the cradle to maintain the clamping force throughout the pipeline temperature range.
