Minimum Bend Radius of Plastic Pipe

thread378-31410

Minimum Bend Radius of Plastic Pipe

Minimum Bend Radius of Plastic Pipe

(OP)
I'm using Polyethylene tubing as innerduct in a gas pipe.  The internal pressure of innerduct is 0 psig.  Would the minimum bend radius specified for innerduct assumed to be used to contain internal pressure still apply, or could a smaller bend radius be used without compromising integrity?  Plastic pipe is often coiled with a bend radius less than that specified for permanent installation.
