The Preinsulated HDPE coil pipe (EPPI-Flex) is made up of HDPE coil pipe, 100% CFC free Polyurethane insulation foam and corrugated LDPE seamless casing.
EPPI-Flex is durable and lightweight. It is easy to install due to its availability in 100mtr long coils that can be custom cut to fit any application. It is easier to handle and requires less number of joints. Core pipe shall be flexible HDPE-PE100 in accordance with ISO 4427/DIN 8074/ DIN 8075 and with pressure rating of 16 bar (SDR11)
Thermal insulation shall be closed cell CFC polyurethane foam; having a density of 48 kg/m3 (minimum) and thermal conductivity coefficient (λ) of 0.0280 W/mK (maximum). The foam insulation is applied over the pipe and then the seamless LDPE jacket is extruded around it.
