SANHE provides a comprehensive range of sucker rod accessory products, from polished rods to downhole pumps. Each product is meticulously designed and engineered to not only meet industry specifications and quality standards but also to ensure exceptional performance during operations.
With corrosion and abrasion challenges becoming increasingly prevalent, SANHE continuously enhances its products through incremental improvements in material selection, manufacturing processes, heat treatment, and advanced surface treatment and coating technologies.
Sanhe offers complete product line of API-11B sucker rod couplings, polished rod couplings and sub-couplings. All couplings are precision- manufactured from heat-treated steel solid bar stock. The raw material undergoes rigorous inspection to ensure reliability and consistency. The threads are cold-rolled to enhance strength, durability, and wear resistance, ensuring reliable long-term performance in demanding applications.

In addition to standard API-11B sucker rod couplings, polished rod couplings, and sub-couplings, SANHE also offers HS couplings. Based on the API design, HS couplings feature a modified chamfer design, enhanced surface finish, and optimized hardness achieved through specialized heat treatment. These improvements deliver superior connection reliability, particularly under high torque loading conditions.

Sitting above the pump and between the sinker bars, stabilizer bars help to centralize the plunger and bottom part of the rod string. Alternatively, stabilizer rod is a hybrid between sinker bar stabilizer bars. It provides both centralization, stability and added weight to keep the rod string from buckling.
