Presenters
Rodney Sands; Harbison-Fischer Manufacturing Company
The polished rod carries the weight of the entire rod string plus the fluid load and the imposed dynamic loads. This paper will show that polished rod failure is caused by fatigue-type stress due to improper installation. It will also review how to recognize the alignment problems and what steps can be done to prevent polished rod failure.
