  • Planning & Construction Considerations

    An important parameter in the design of a crossing by means of horizontal directional drilling is the bending radius or radius of curvature. The bending radius is determined by the bending characteristic of the product pipe, increasing with the diameter. It is usual in designing HDD paths to consider a bending radius equal to 1000 times the
