Withstands High Breakout TorqueTests under bottom hole temperatures ranging from 50° through 400° F showed Bakerlok withstood greater torque than standard joint welded in three places with 2-inch beads. Unaffected by Vibration.At 400° F Bakerlok was subjected to steady vibration from a 6 lb air hammer. Breakout torque was increased until six times the 3,000 ft-lb makeup torque finally broke the joint.
