Inflex EHD is designed for all kind of pipes for transporting liquids in heating, sanitary installations and district heating systems. The main advantage of this pipe is the amount of space inside giving more freedom of choice of medial pipe to be put inside. The pipe is made from external HDPE corrugated pipe with flexible EPE foam insulation inside. A multilayer layer elastic foam provides excellent thermal insulation over a wide temperature range. The insulation's closed-cell structure prevents water absorption and water vapour permeability. Due to high impact resistance and mechanical strength EHD-PE can be buried underground and is suitable for areas where there is a risk of mechanical damage. The external layer is resistant to oil, corrosion and most chemicals. The materials used and the construction of the pipe allows high flexibility, small bend radius and easy handling.
