Unidelta pipes in PE-RT (Uniert, TriPert and MultiPert Plus) are made using PE-RT type II, defined by standards EN ISO 22391 and DIN 16833/16834 as the PE-RT raw material with the highest mechanical strength Unidelta PE-RT pipes can be used at an operating temperature up to 70°C and their excellent flexibility makes them extremely easy to bend. Due to these characteristics, they are mainly installed in radiant heating systems.
