API Two-way Globoidal Protection sucker rod coupling

The Two-way Globoidal sucker rod coupling is our new sucker rod coupling which is processed with some special technology .It' not only coated a layer of abrasion-proof ,corossion resisting and lessening friction coat. What's more, there is a big arc on its surface. So it can not only protect itself but also the pipeline, preventing and slowing down the wear. so that the life of the coupling and pipeline are significantly prolonged,and the operating costs of oil reduced, oil production increased.
