HDD Pilot Hole Geometry Verification

Once the pilot hole is drilled, its as-built geometry rarely matches the design line exactly. This tool compares the surveyed curvature, joint-to-joint bend angles, and minimum radius against the design tolerances to confirm the bore is still drillable and that the product pipe can be installed without exceeding its allowable bending strain.

Catching an out-of-tolerance dogleg at the pilot stage — before reaming and pullback — is far cheaper than discovering it as a stuck or over-stressed pipe string.
