HDPE Pipes
SANS covers three different material designations namely, PE 100, PE 80 and PE 63. Considerable strides have been made to improve the quality of HDPE material and its ability to withstand pressure.
These material designations are based on the long term hydrostatic strength known as the Minimum Required Strength (MRS), The MRS is determined by performing regression analysis done in accordance with ISO 9080. Extrapolation of the regression analysis shows ZAMPIPES have a minimum design life of fifty (50) years.
Applying a design coefficient of 1.25 to the MRS, ZAMPIPES conform to SANS 4427.
