Hdpe minimum bend radius
WebCreated Date: 2/5/2004 5:55:42 PM Webof curvature is limited by the bending radius of the drill rod and the pipe. More often, the permitted bending radius of the drill rod controls the curvature and thus signifi cant bending stresses do not occur in the pipe. The designer should minimize the number of curves and maximize their radii of curvature in the right-of-way
