Product Description

Sucker Rod Couplings

Product Specifications:

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, the base metal is prepared to a No. 1 NACE TM0170 or TM0175 finish prior to the spray metal coating process. The spray coating process is conducted to prevent coupling abrasion wear or coupling corrosion.
