Sucker Rod Coupling

Date:2024-05-08 Popularity:475

RockySea Sucker Rod Coupling



The sucker rod couplings are used for connecting sucker rods, polished rods and sinker bars. Material of the couplings is high quality carbon steel or alloy steel, which are conform to and exceed the requirements of intl standards.


Description 

According to surface of suck rod couplings, they can be divided into sucker rod couplings with smooth surface and sucker rod couplings with wrench square.

Sucker rod couplings with wrench square.

Sucker rod couplings with smooth surface

According to different needs, RockySea Petro provides users couplings under different processes. All of the three types have two surface treatment classes: class T and class SM. The class T stands for through-hardened and the class SM stands for sprayed metal. The outer diameter of the sucker rod couplings has FS(full size) and SM(slim hole) types.



The main types of RockySea Petro rod couplings include sucker rod couplings, polished rod couplings and sub-couplings. The Sucker rod coupling has same box thread size in both end. The polished coupling is designed to connecting polished rod and sinker bars. The sub-coupling is also called cross over coupling. It has different box thread size in both ends.


Data sheet 

Specification
  • Type: sucker rod coupling, polished coupling and sub-coupling.
  • Grade: T and SM.
  • Length: 4″, 4.5″ and 5″.
  • Thread size: 5/8″, 3/4″, 7/8″, 1″and 1-1/8″.
  • Material: high quality carbon steel or alloy steel, such as AISI 1045, AISI 4135.

Features

Application 

The sucker rod couplings are used for connecting the sucker rod and sinker bars with the same dimensions. But it is not used in the polished rods, which may cause the fracture of the couplings. The polished couplings are designed to connect the polished rod and sinker bars. The sub-coupling is widely used for the connection of different sizes of sucker rod, pony rod and sinker bars.

Good corrosion and wear resistance. Black oxide coated for anti-galling and lubricating properties. Automatic flame spray production minimizes the tolerance.
