Pipe systems for industrial construction

Industrial pipes are required for a wide variety of production processes. The demands placed on them are diverse. Whether it’s pipes for compressed air, industrial heating, chemicals, solids or inert gases or for the energy-efficient transport of coolants and cooling brines – our RAUPEX and RAUFRIGO industrial pipes provide you with system solutions that are convincing across the board. Cost-efficient to install and operate, they can be flexibly adapted and extended and are reliably functional for industrial pipe constructions.

RAUPEX. Pipe systems for industrial construction

The universal system for large-diameter pipes RAUPEX is suitable for transporting compressed air, argon, nitrogen, vacuum, cooling water, heating water, chemicals, solids and more. The five different pipe colours enable colour assignment in accordance with DIN 2403 or the company's own factory standards. You can see immediately what is flowing. Additionally – thanks to our compression sleeve and SMARTFUSE jointing technique, the system for industrial pipe constructions is permanently sealed. Safe and flexible in operation, it can be expanded at any time, even under pressure.

RAUFRIGO. Cooling pipe system

With the RAUFRIGO pre-insulated industrial pipe system, you can transport refrigerants, cooling brines or process media safely and quickly. The polymer carrier pipe is insulated with rigid polyurethane foam and then protected with a metal outer casing – for large spans and fast installation.

Compression sleeve

Secure without O-ring. Our compression sleeve technology for industrial pipes offers many advantages: a large cross-section, no O-ring and visual controllability. It is easy to learn, safe to operate and, above all, fast.
