Sucker Rod Coupling The sucker rod couplings are used for connecting sucker rods, polished rods and sinker bars. ** The main types of sucker rod couplings are sucker rod couplings, polished rod couplings and sub-couplings. ** All of the three types have two classes: class T(through-hardened)and class SM (sprayed metal). **Material: carbon steel, alloy steel. **Specification:5/8", 3/4", 7/8"1", 1 1/8"
Advanced thermal spraying technology is adopted to melt Ni alloy and other high wear-resisting materials on the blank surface of the collar after high temperature flame spraying, so as to reduce the friction coefficient between the anti-wear collar and the oil pipe to 0.01, which is an effective combination of high hardness and low friction, thus improving the service life of the rod and pipe in oil exploitation. Sucker Rod Coupling Designed and manufactured according to API spec 11B. The couplings are manufactured in grades SM and DES. Increased wear and corrosion resistance. Surface treatment includes black coating, phosphating or as per the customers requirement.
Many sizes of hollow rods for different usages. Its steel degree is high, and it can withstand strong torque and tension. Mechanical properties are H-grade level. When it is used in deep well, the performance is more reliable with the use of three step assemblage. It can come to the depth of 3,000 meters.
Hollow sucker rod
