Hi,
I met a problem abour HDPE pipe. There are 2 codes related with HDPE pipe:

ASTM D3035
Standard Specification for
Polyethylene (PE) Plastic Pipe (DR-PR) Based on Controlled
Outside Diameters

ASTM F714
Standard Specification for
Polyethylene (PE) Plastic Pipe (SDR-PR) Based on Outside
Diameter1

The only difference I found is that the pipe Dia is from 3" to 54" in F714, and from 1/2" to 24" in D3035;

Any other differences between the two codes?
