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

    2002-6-1 · Bend radius by definition is the forward distance required for a drill string to make a 90-degree turn (see figure on pg. 61). In practicality, bend radius is an indication of how much bending a pipe can take without doing significant damage to the drill stem. In the past, drill pipe manufacturers used different methods to establish the bend radius rating for the their pipe.

    2021-5-20 · Exceeding the allowable bend radius can result in significant damage to the pipe or drill rod. While drill-rod manufacturers may use different methods to establish the bend-radius rating for their pipe, SAE standard J2022 provides a voluntary guideline for evaluating drill rods using the same baseline. It is necessary to know what method of calculation is being used by a manufacturer when comparing the bend radius of drill rods from different manufacturers.

  • Choosing Drill Rods for Trenchless Tunneling

    2017-12-12 · In addition to calculating the total length, the bend radius of the drill rod is also calculated. Essentially, the bend radius is the forward distance a drill string must make to make a 90-degree turn. The exact calculation to determine the bend radius of a rod varies from manufacture to manufacture. However, exceeding the calculated variance damages the rod.
