  • Drill Master: Understanding Bend Radius - Trenchless ...

    2002-6-1u2002·u2002The largest bend radius of either the drill pipe or product pipe is the number that must be used for planning and completing the bore. What is the penalty for exceeding the bend radius of the drill pipe? From a monetary standpoint, it can be significant. When the bend radius is exceeded, the useful life of the drill pipe decreases dramatically.
