Re: HDPE pipe size

Dear Jack,

You are very right...in my own experience, the largest HDPE pipe that I had experienced is only 250mm. The problem with HDPE pipe with very large diameter is the joint fusion. Maybe it is not very preferable to use HDPE pipes with very large diameter due to its material properties. I think CL/CC (cement lined/cement coated) steel pipe is advisable.
