🚜 ASTM F1962 HDD Geometry (Bend Radius R = 100 x Pipe Outer Dia, Pitch %)

Horizontal Directional Drilling (HDD) Geometry Calculator

Design 3D guided bore paths for trenchless pipe and fiber installation beneath rivers and highways under ASTM F1962 & PRCI guidelines: calculate minimum allowable elastic bend radius (R = 100x to 120x pipe outer diameter for steel and HDPE to prevent plastic yielding), drill rod maximum bend limits (3.0° per 10-ft rod), entry/exit angles, and HDD profits.
