Uni Pipe Plus

Highly flexible multilayer pipe for dim. 16 - 32 mm

Uni Pipe Plus

Uni Pipe PLUS multilayer pipes safe time and costs during drinking water installations

More flexibility and bendability than current multilayer composite pipes

Uni Pipe PLUS consists of a seamless or OWC-technology aluminum pipe which not only prevents oxygen from entering, but also compensates for restoring forces and linear expansion caused by changes in temperature.

The coils of the multilayer composite pipe Unipipe PLUS are significantly more flexible and bendable than current multilayer pipes. This enables you to not only save time during installation, but also save costs caused by extra installation components, which are now no longer needed.
In contrast, Uni Pipe PLUS straight lengths feature a special aluminium layer that is more rigid than conventional. So you can provide a visually attractive, on-wall mounting solution which optimally caters to today’s modern installation technology. Whichever variant you need, you are guaranteed the highest safety possible.
