Class T Full Size and Slim hole Coupling
Our company produces coupling including sucker rod coupling, sub-coupling and spray metal coupling, they are design according to API Spec 11 B standard.
Our company produces coupling including sucker rod coupling, sub-coupling and spray metal coupling, they are design according to API Spec 11 B standard. These API Class T couplings are made of 4135 alloy steel and offer excellent resistance to hydrogen embrittlement. They are furnished with all Weatherford sucker rods unless otherwise specified.
Product Description
● Introduction
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”
● API Oilwell sucker rod coupling
1.Size: from 3/4" to 1" slim hole full size
2.Placement: female
3.Technics: hot rolling
4.Grade: T,SM Grade T Sucker Rod Coupling
These API Class T couplings are made of 4135 alloy steel and offer excellent resistance to hydrogen embrittlement. They are furnished with all Weatherford sucker rods unless otherwise specified.
● Grade SM Sucker Rod Coupling
These SM Sucker Rod Couplings are made of 4135 alloy steel and offer excellent resistance to hydrogen embrittlement. This provides a strong metallurgical bond between base metal and the spray metal coating
