Ultra High Strength Sucker Rod
In the environment with non-corrosive or light corrosive medium, ultra high strength sucker rod is often used in deep wells or oil wells with big pump volume. It can effectively prolong the oil recovery cycle and reduce the pump hanging weight. Ultra high strength sucker rods newly developed by our company are made from alloy steel. They have same dimension, structure and parameters with Grade D sucker rod, but its strength is much higher than sucker rod. Based on Grade D sucker rod, Grade HY adopts the surface strength of a special surface quenching strengthened rod body, which effectively improves the
anti-fatigue performance of rod body.
