STRUCTURAL FEATURES AND PERFORMANCE
The PE-RT/AL/PE-RT multilayer pipe for underfloor heating, heating and sanitary systems, belongs to the new generation of multilayer pipes for plumbing-sanitary systems.
It consists of composite material, made even and more solid by a technologically advanced process, with which a PE-RT (crosslinked polyethylene with high resistance to high temperatures) pipe is implemented, reinforced by an aluminium core, 0.2 mm thick, welded and covered externally by another layer of PE-RT.

REGULATORY COMPLIANCE
The FIVPert pipe complies with UNI EN ISO 21003 standard (class 2/10 bar, class 5/10 bar) and with the Ministerial Decree Italian 174/2004.
In addition, the FIVPert 16x2 pipe has achieved the DVGW (Technical Rules W542 and W534) and KIWA (Technical Document Ki-0410) quality certificates.

CONDITIONS OF USE ACCORDING TO THE APPLICATION CLASSES PURSUANT TO UNI ISO 21003 (SEE TECHNICAL ATTACHMENTS).
