    Polyethylene Properties - pipe in Mexico

    The first PE pipe material used in engineering appliions was Type 50 High Density PE (HDPE) with a long term stress of 50MPa. Subsequently, Medium Density (MDPE) materials, with improved pipe properties when compared to the earlier high density materials, were used in pipes due to their improved flexibility, ductility, slow crack growth resistance and crack propagation resistance.

    the internal roughtness coefficient of HDPE to the flow of fluid are less than any other types of pipe. The use of HDPE type corrugated pipe provides excellent flow performance, so the same flow rate quantities can be achieved using the corrugated pipes having smaller diameter, emit smooth laminar and cotrolled flow charasteristics.
