RAUVIPEX. Accelerating your journey to net zero

RAUVIPEX district heating pipe does it all.
Whether you are connecting a heat pump for individual buildings or for transporting heat within a heat network—RAUVIPEX is the all-round performer.
Quick and flexible to install, RAUVIPEX offers the optimum combination of thermal insulation and flexibility.

Safety for the long haul. RAUVIPEX not only offers impressive insulation properties, it has many safety features you can rely on for decades – including a robust outer jacket, a fully bonded pipe system and the trusted REHAU PE-Xa carrier pipes.

Extremely versatile. A range of product variants, a broad spectrum of sizes and unparalleled compatibility – RAUVIPEX can be used across multiple applications.

Saves construction time and costs. The improved flexibility of RAUVIPEX makes installation much easier For you it means: reduced bending forces and faster construction time. The pipe structure allows more compact pipe coiling. The new standard coils with a reduced outer diameter of 2.4m can now be transported much more cost-effectively by standard HGVs. Special project-specific coils with widths of up to 1.6m and heights of up to 2.8m are available.

Products

RAUVIPEX

pre-insulated pipe for heat networks

Endless possibilities: To support limitless versatility of applications, RAUVIPEX is available as a UNO and DUO pipe in dimensions d20 to d140.

1 Outer jacket:
The unique geometry of the pipe’s outer jacket cleverly combines flexibility and safety: U-shaped wave crests with wide contact surfaces and high wall thickness make it extremely robust for deployment on construction sites. In combination with the V-shaped pipe troughs, the jacket is noticeably easier to bend during installation.

2 Longitudinal watertightness barrier:
Welded all around, the longitudinal water barrier offers the best possible protection against moisture penetration into the pipe insulation, even if the outer jacket is partially damaged.

3PUR foam:
For professional heat and cooling distribution. The newly developed formula for fine-pored PUR foam combines outstanding insulating properties with excellent bending elasticity.

4Carrier pipes:
Reliable transport of hot and cold water: Our extremely durable PE-Xa carrier pipes in REHAU quality – tried and tested for more than 40 years.
