تاثير بعض المركبات الهيدروكربونية على القيم المميزة لمنحنيات (القوة – الاستطالة ) لانابيب البولي ايثلين عالي الكثافة HDPE المستخدمة في جر مياه الشرب

The aim of this research is to study the absorptive effect of high density (HDPE) polyethylene pipes for the hydrocarbon compounds on the characteristic (Force, Elongation) curves. To verify this, we immerse some parts of the pipe in different hydrocarbon mediums containing gasoline, diesel, and motor oils of (10 and 40) calibre. The result show that these compounds have a bad effect on the submission force, neck formation, and damage force. The experimental results also show that motor (engine) oils have a similar effect on gasoline despite low absorption percentages.
