Sucker Rod and Polished Rod

Sucker rod is one of our main products which built up by the essence of advanced technology from home and abroad. Product categories are organized and manufactured in accordance with API SPEC 11B, SY/T5o29 standards. Using the special processing techniques, we have developed the sucker rod with ultra-high strength, high strength, and high toughness, surface coating material and the HL, HY, KD, D grades.
In addition, we also have rod products with high-strength, high-corrosion resistance in accordance with the non-API design standards for special purposes. As the material used in the sucker rod, we have developed the special material with high-strength and high-corrosion resistance with the Xi'an communication University and cooperated with many larger international manufacturers to produce different rod products with a variety of performance levels. These have been widely adapted by various domestic and overseas fields. Currently, our production capacity for the sucker rod products is about 5 million meters annually.
