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.
Sucker Rod Coupling is a joint for Sucker rod, used in oil well downhole for oil pumping and Production. Yunsheng sucker rod couplings are manufactured from high quality Alloy Steel AISI 5140, fully in accordance with API Spec 11B standard, including class SM coupling, class T coupling, Sub coupling, Full Size, Slim Hole and Over Size, and the thread size are available at 5/8â??, 3/4â??, 7/8â??, 1â?? and 1 1/8â??.

Sucker rod is the common equipment in the oil extraction. It is manufactured through many process including the testing, straightening and forging. The sucker rod is placed between the polished rod and oil well pump. To deliver power. Sucker rod is manufactured from high quality carbon steel and alloy steel, which is conform to the API Spec 11B standard. Sucker rod has various types including the common sucker rod, hollow sucker rod and FRP sucker rod. Commonly we use the sucker rod coupling to connect the sucker rod. The sucker rod also has various specs to fit different environments and applications
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.
