HDPE plastic pipes for potable water :

Advatages :
1- HDPE produced dia. from 20 mm. up till 450 mm.
2- HDPE are produced in the form of coils of 100 - 200 - 300 longitudinal meter for ODs.up till 160 mm., if of larger dia., they are produced in the form of pipes of 10 -12 longitudinal meter .
3- HDPE pipes do not form any toxic materials , import neither taste nor odor , suitable for man use .
4- Low frictional coefficent avoids bactteria development on intererior surface .
5- withstand 40 degrees C. temperature .
6- HDPE pipes do not break down or explode, welded points are much stronger that other parts of the pipe , earthquake resistance .
7- Ability to withstand external harmful forces, thus PE pipes serve for about 50 years compares with iron pipes which serve for 15-20 year .
8- Resistance to many chemical agents, electrical currents and traffic viprations .
