Sucker Rods
Quench & Tempered Rods Vs Normalized & Tempered Rods
For decades, the sucker rod market has lacked the infrastructure to mass-produce quality Quenched & Tempered sucker rods. The machinery is costly, the process is difficult to master, and the industry has widely defaulted to the more easily manufactured Normalized & Tempered rods.
Today’s operators are missing out on the most substantial benefit of Quenched & Tempered sucker rod – Fatigue Resistance. And it’s what our rods do best. Stress cracks are inevitable with all steel, especially under stress loads. The fatigue resistance of a steel determines how resistant to failure a rod will be once those stress cracks initiate. Aside from chemical programs, well design, rod handling, and many other variables that plague sucker rod failures. Operators should have confidence that the rod they’re receiving is the most durable and reliable product they can find. Below are the results of a blind Charpy Impact test which was conducted by an independent, third-party metallurgy lab in Houston. They collected “KD” (4320, 4330, 4720, etc.) and High Strength (4138, 3130, etc.) rod samples from all major manufacturers to conduct this test. The test results unanimously showed that Q&T rods are more fatigue resistant than N&T rods in all categories, but most notably in high strength applications.
