It's #150.
PN 20 is equal to ANSI 150 & ANSI 300 equals PN 50.
PN16 and ANSI 150 are not the same, although they are often used in similar applications. PN16 refers to a pressure rating in bar for European standards, indicating a maximum pressure of 16 bar at a specified temperature. In contrast, ANSI 150 is an American standard that denotes a pressure rating of 150 psi at ambient temperature. The two standards are based on different measurement systems and may have variations in flange dimensions and pressure capabilities.
The PN16 flange is equivalent to either the ASME 150 or 300. The PN is related to Nominal Pressure and the ASME is the standard for the American Society of Mechanical Engineers.

Answer I'm no expert here with this but through minimal experience with HDPE pipe, PE stands for polyethylene and is used for water supply because polyethylene is neutral in water - meaning nothing in polyethylene reacts with water which would seep into the water. There are different pressure grades "PN" which must be considered for your specific use. PN 2.5 through PN16 indicate how much pressure the pipe can withstand.
