Polished Rods

Exceed polished rods are manufactured and inspected to be fully compliant with API-11B spec. All Pin Threads are cold-rolled to ensure the most durable connection during operation. Creating a much stronger pin compared to old cut thread or burnished process. The rolled threads improve the fatigue performance of the polished rod significantly and reduces common polished rod failures at thread roots dramatically.
