Tubes

PRODUCT

This Polyethylene Raised Temperature tube is made of 5 layers. The first and the fifth layer are made of PE-RT type 1. The second and fourth layers are an adhesive layer for the attachment of the third layer, the EVOH layer. This layer guarantees that the tube stops the oxygen diffusion. The U-tube is impermeable to oxygen diffusion according to DIN 4726. 

FEATURES

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.
