For example, an NC38 on 3½-in., 13.30-lb/ft G-105 drill pipe is downgraded to Class 2 when the OD wears below 4 21 ⁄ 32 in. At this diameter, the tool joint is less than 80% as strong as Premium Class pipe. The HT 38 connection can tolerate wear down to a diameter of 4⅜ in. before it reaches the same limit.

TurboTorque is a family of three distinct connection configurations designed for the specific and different needs of each individual pipe size. For 3½- to 4½-in. sizes, connection torque capacity is of primary importance. The common use of these sizes makes makeup speed more desirable than incremental hydraulic gains.
