PN = Nominal Pressure.represents the symbol PN and the maximum allowable operating pressure at a given temperature（Such as : PN8, PN10, PN12.5, PN16, PN20, PN25）
SDR = Standard Size Ratio. [SDR=DN/Wall Thickness]（SDR6.3, SDR7.4, SDR9, SDR11, SDR13.6, SDR17, SDR21, SDR26, SDR33）
PE = Grade of HDPE Resin, like PE100, PE80, PE63 etc.
HDPE = High Density Polyethylene (Usually refers to PE100, PE100-RC)
PN 10 denotes the pipe is designed for working pressure of 10 Bar. [1bar=14.5psi]
