Preinsulated flexible pipe systems made of cross-linked polyethylene core pipe and polyurethane insulation for hot potable water supply applications.
Advantages of HeatFlex Sanitary system include: quick and convenient installation, narrow pipe trench and tight bending radius of the flexible bonded system.
HeatFlex Sanitary carrier pipe is made of PEX-a SDR7.4 guaranteeing maximum pressure of 10 bar at 80°C continuous working temperature.
This highly efficient pipe system boats an outstanding thermal conductivity value of 0.021 W/mK.
HeatFlex Sanitary is the best solution for:

HeatFlex pipes are connected using press or clamp connectors of different configurations (weld adaptors, couplers, elbows, tees).
The installation of the press connector requires the pipe end to be expanded before placing the metal insert into the pipe; this is followed by the compression of the outer sleeve onto the pipe’s outer surface with use of an industry-standard PEX press tool.
To install the clamp connector no need for pipe end to be expanded is required: the fittings installation is done with use of a conventional nut driver without the need for any special tooling.
The foaming of pipe joints is made with insulation shells of different configurations:
– straight piece
– elbow 90°
– tee branch
The sealing of the joint against water and humidity penetrations is guaranteed by special lateral gaskets perfectly fit to the external corrugated casing of the pipe.
These insulation shells are quick and easy to install without the need for special tooling.
