Q2-Shear Tool is designed to protect sucker rod string from excess stress. It is designed to fail at a predetermined load, which is less than the maximum allowable load of sucker rod string.
Q2-Shear Tool is used to disconnect the sucker rod string from the pump when pump seizes or rod gets stuck in the tubing or seating nipple. To ensure maximum coupling wear resistance, a high strength steel with excellent work hardening characteristics has been selected. Shear pin holes have sufficient counter sinking to permit moderate coupling wear without the possible loss of shear pins.
