Materials and their Characteristics # 1982 York
Plastics as engineering structural materials are becoming more and more popular in Egypt. In the present paper, the status of the on-going activities on weathering degradation of plastics pipes is presented. Two types of pipes are being considered, namely : (a) PVC plain pipes produced by the National Plastics Co.,and (b) PVC corrugated perforated pipes produced by the Eayptian Authority for Aqricultural Drainage. The effects of outdoor exposure for about a year and UV accelerated exposure on material properties and pipe performance, as determined from various mechanical tests are presented.
