DIP polywrap
DIP polywrap
(OP)
I have a DIP that is spec'd out to be wrapped in Polyethylene encasement, 8 mil thick. I've never used or been on a job that called for polywrap, and basically I'm afraid that the contractor will have a difficult time keeping wrap intact during installation and when he taps the main. Has anyone used this product before? If so, was it flimsy and easily damaged by construction activities?





RE: DIP polywrap
If you haven't seen it used before, or your contractor hasn't used it, I believe DIPRA has a brochure that shows how to properly install.
If they are going to do taps on the line after it is wrapped, you need to make sure that the polywrap is sealed good around the tap.
Also as with all metal pipes you should make sure you have some type of cathodic protection.

You can actually pull the material through the bore hole with the pipe without problems when you are directionally drilling.
Contact DIPRA for further information.

I think DIPRA and/or DIP manufacturers also have other specific publications, and videos etc., that are helpful specifically in installer training/instruction etc. involving such means of corrosion protection.
