Grade D sucker rod produced by our company has reliable quality and excellent performance, which obtained the right of using API logo in 2013, and won the honorary title of famous brand products in Shandong Province.
The series products are made of high-quality low carbon alloy steel, adopting heating patent technology independently designed in casting, so that casting quality can be strictly controlled. Domestic advanced technical equipment for thermal treatment are adopted for integrally hardening and tempering so as to ensure the overall mechanical performance, and numerical control processing of the rod heads ensures the threaded precision and intensity. Through the technology mentioned above, the sucker rod is ensured to have excellent integral performance.
Grade D sucker rod produced by our company has high tensile strength and good performance of bearing larger asymmetrical cyclic load and resisting corrosion, and has been widely used in oil extraction.
