In the past, copper pipes were mainly used in domestic installations. Today, plastic and multi-layer composite pipes are becoming more commonly used. The benefit's are obvious: Multi-layer composite pipes feature excellent flow properties and are highly resistant to incrustation, thanks to their superior chemical resistance. FRÄNKISCHE „alpex“ pipes are physiologically sound and suitable– a combination that ensures safe and easy handling, and reliability in daily use. Unlike copper pipes, plastic/metal multi-layer composite pipes are not prone to pitting corrosion.
Multilayer Composite Pipe
Robbens underfloor heating pipes are high-quality multilayer composite pipes from FRÄNKISCHE, a leading European manufacturer of building and industrial pipes and the strong brand behind Robbens Systems.
The cross-linked multi-layer composite pipes have a butt-welded aluminium core. The two plastic layers and the aluminium layer are permanently bonded together by adhesive layers – providing excellent reliability, extreme durability and longevity.
The underfloor heating pipe can be easily bent which reduces or eliminates the need for connections and fittings. The multi-layer composite pipe allows for optimum bend radii. No special tools are required to bend the pipe of a diameter of 16 x 2.0 mm. All bends needed for underfloor heating applications can be easily made by hand. The continuously welded aluminium mid layer gives the pipe dimensional stability and reduces its tendency to spring back on bending.
