High density polyethylene - HDPE - is a very popular material for water pipes. It is resistant to chemical easy and light weighted, long life time, low friction,  relatively cheap, flexible and   sun resistant. PE pipes can be used in range of temperatures -40 oC to 60 oC considering the change of operating pressure. Typically the standard specification identify class of a HDPE pipe is by the nominal pressure class ( PN ) up to PN 20 or 20 bar. HDPE pipe can also be classified by the material used ( PE 100, PE 80, PE63, PE 40 or PE 32)
