Two different grades of Sucker Rod Couplings are available: T and SM. The manufacturing process of both the grades is the same with cold worked pre-stressed, roll-formed threads with the anti-galling coating. This process results in stronger/fatigue resistant threads.
The manufacturing inspection, the dimensions and the tolerances of the couplings match or exceed the specifications of the latest API standards.
Grade T Sucker Rod Couplings
These couplings are made up of 5140 alloy steel and are very resistant to hydrogen embrittlement.
Grade SM CO-HARD Sucker Rod Couplings
These couplings are made up of 5140 alloy steel and are very resistant to hydrogen embrittlement. In order to yield a strong metallurgical bond between the base metal of the coupling and the spray metal coating. 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.
1. Designed and manufactured according to API spec 11B.
2. The couplings are manufactured in grades SM and DES.
3. Increased wear and corrosion resistance.
4. Surface treatment includes black coating, phosphating or as per the customers requirement.
