Product Description

Product Description

 

Sucker Rod Couplings

Sucker Rod Couplings are manufactured from quenched and tempered alloyed steels. API 11B couplings are classified into two classes: T Class and SM Class (Spray Metal).

SM Class coupling has a spray-welded metal layer on the surface. The appearance is silver-white generally, the surface hardness is high, and the wear resistance and corrosion resistance are relatively good.
Compared with T Class couplings, SM Class couplings have the following features:
(1) High surface hardness and good wear resistance
According to SY/T 5029-2013, the surface hardness required for T Class couplings is HRA56~62, and the metal hardness of the spray welding layer of SM Class couplings is ≥595HV0.2.
(2) The surface finish is high. The surface roughness required for T Class coupling is ≤ 3.2, and that of SM Class coupling is ≤ 1.6

Our sucker rod couplings, reducer couplings, small wellbore couplings, spray welded couplings and polished rod couplings can meet the requirements of API 11B. We can also produce couplings of different classes according to the requirements of our customers.

Polished Rod Coupling

Polished rod coupling is designed to connect polished rod and sucker rod. Sucker rod coupling cannot be used to connect polished rod; polished rod coupling can be used to connect sucker rod.
