Heat-shrinkable cover REHAU RAUTHERMEX for DUO pipe 50+50/182

Heat-shrinkable cover REHAU RAUTHERMEX for DUO pipe 50+50/182 is a factory-made thermal protection sleeve engineered to fit DUO-profile pipes with a 50+50/182 geometry. The product is made from a cross-linked polyolefin material that, when heated, shrinks to form a dense protective layer around joints, transitions and exposed pipe sections. It provides combined thermal insulation and mechanical protection aimed at reducing heat loss and shielding pipework from moisture, dirt and minor mechanical impacts in heating, plumbing and utility installations.

Advantages

The REHAU RAUTHERMEX cover delivers a uniform, close-fit insulation layer without the need for complex mechanical fastenings. Its shrink-fit behaviour ensures reliable adherence to the pipe profile and maintains shape stability after cooling. The material resists common environmental factors encountered in building services and utility networks, including moisture and dirt, and offers improved mechanical resilience compared with untreated pipe surfaces. The product is produced to match the DUO 50+50/182 profile, allowing quick alignment and installation at joints and transitions.

Suitable for

• Insulating joints and transitions on DUO 50+50/182 pipes in heating systems
• Protecting exposed pipe sections in plumbing and utility conduits
• Field repairs and retrofit insulation where a matched DUO profile is required
• Applications requiring combined thermal and mechanical protection of pipework

Key specifications

• Designed for DUO-profile pipes with 50+50/182 geometry
• Heat-shrinkable cross-linked polyolefin construction
• Provides thermal insulation and mechanical protection
• Shrink-fit installation creates a tight, durable outer layer
• Suitable for use on joints, transitions and exposed pipe sections

How to use

Position the RAUTHERMEX cover over the prepared pipe joint or exposed section ensuring correct alignment with the DUO 50+50/182 profile. Apply controlled heat using an appropriate heat gun or shrink device across the sleeve surface, moving steadily to achieve even shrinkage. Continue heating until the sleeve attains a close-fit around the pipe profile and any wrinkles or gaps are eliminated. Allow the sleeve to cool and verify that the fit is consistent and secure before returning the system to service.

Usage recommendations

Ensure surfaces are clean, dry and free of loose material before installation. Use a heat source that allows temperature control to avoid overheating and potential damage to the sleeve or underlying pipe. For long-term performance, verify compatibility with the operating temperatures and environmental conditions of the installation site and follow local installation codes and safety practices.
