Cryogenic Pipe Support Systems - Rilco …

1 Cryogenic pipe Support Systems Overview Rilco Cryogenic pipe supports are developed to Support cold piping in various applications ranging from chilled water to liquefied natural gas. The qualified service temperature is from -425 F (-253 C) to 275 F (135 C). Rilco Cryogenic supports are the latest technology in cold pipe Support Systems . These supports are an innovative design that utilizes the most efficient and cost effective materials that provide long-term energy savings. Since the supports are pre-insulated the expensive process of welding to pipe is eliminated and leads to labor cost savings since our installation process has been completely streamlined. Furthermore, the threat of CUI (corrosion under insulation), or any associated field corrosion problem, has also been eliminated with the implementation of Rilco s latest Cryogenic Support technology.

Guided 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 . Anchor Insulated supports that restrain the pipe vertically, laterally, and axially.

4 Anchor supports are provided with guide clips that prevent lateral movement. Clamp Hanger Insulated supports that restrain the pipe vertically by using an insulated pipe clamp. The pipe is supported by the clamp and the insulation is located between the clamp and the pipe . Support Components Type Photo Description High Density Polyurethane Foam One of the best materials for cold insulation. Rilco produces various density supports and can also customize the density to specific project needs. The foam section can be stepped both radically and longitudinally to tie in with the same layering thickness as the line insulation to prevent straight heat path to the pipe .

5 For alternative insulation options contact a Rilco sales representative. Vapor Barriers A paper or plastic back sheet that wraps 360 around the foam section that protects against moisture ingress. The vapor barrier is glued to the foam and overlaps the joint between the two insulation halves by at least 1 in/25 mm. Protective Mastic If pipe supports are installed before the insulation is installed, we will apply protective mastic on the exposed surfaces of the supports to protect from the weather conditions until the insulation installation is completed. Outer Sheet Metal Jacket The metal jacket is typically wrapped around the foam section and outside the vapor barrier and is a typical feature on most Rilco designs.
