YOUR OWN COLOR, YOUR OWN TEXT, YOUR OWN CERTIFICATION?
As a system manufacturer you want to stand out. U-Tube Systems makes this possible. A pipe in your own color, with the name of your brand. The options also include your own KOMO certification. In this case the, a color pigment is applied to the adhesive layer that the EVOH layer is fitted on, with permeability to the oxygen diffusion. Thus, the basic PE-RT layer remains intact and the thermal features of the pipe remain optimal.
This Polyethylene Raised Temperature pipe is made of 3 or 5 layers. The first layer or the basic layer is made of PE-RT type 1. The second layer is an adhesive layer for fixing the third layer, the EVOH layer. This layer guarantees that the pipe stops the oxygen diffusion. The U-Tube Systems pipe is impermeable to the oxygen diffusion in accordance with DIN 4726.
The PE-RT type 1 resin has a good flexibility. It is an ethylene-octene copolymer with a unique molecular structure, based on a controlled distribution in a side chain. Consequently, it proves its higher behavior with respect to the lifetime until breakdown, without requiring the crosslinking PEX.
The PE-RT type 1 resin is optimally stabilized anti-ageing, so that the piping systems fitted on these PE-RT have a calculated lifetime of at least 50 years under normal operating conditions, based on the internationally accepted regulations. In addition, the material is authorized as per the most used regulations with respect to drinking water.
The pipes made of PE-RT type 1 resin may be used at a temperature range of 5ºC to 80ºC. The short-term peak charges of up to 95ºC at an internal hydrostatic overpressure of 6 bar at most are supported without any issues.
