Manufacturing Process
Exceed polished rod are manufactured and inspected to be fully comply with API-11B spec. Pin threads is cold-formed and rolled, 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.
