New Rod Inspection
New rods are measured with calibrated precision instruments to ensure conformance to all API Spec 11B specified dimensional tolerances, as well as detection of rejectable process-of-manufacture conditions such as forging flaws, machining flaws, thread rolling flaws, and bar rolling flaws. Pin and coupling thread forms are verified with API P-6, P-8, B-2, and B-6 gages. Body straightness is verified with total indicator runout (TIR) measurement.
Historically, our reject rate for new sucker rods has ranged between 2% and 12%. Typically, every string of new rods that is inspected will have rejects, with some strings having over a 20% reject rate.
In addition to identifying reject rods in a new string, our inspection process will reduce the residual stresses in your rods which resulted from the manufacturing process, and we will improve the corrosion resistance of your rod. Through our shot peening process, we will increase the case hardness by the pre-stress compression applied at the surface of your rod.
