API Female male threaded sucker rod reducing coupling API 11B slim Hole Sucker Rod Coupling
Introduction
The suck 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 API Specification 11B.
Production
· The sucker rod couplings are manufactured in their own dedicated line.
· Cleaned → prepared → loaded on mandrels → shot blasted → flame sprayed →induction fused.
· The flame spray process is a computer controlled, menu driven operation that holds spray application
· tolerance to within two thousandths of an inch.
Classification
· The main types of sucker rod couplings are sucker rod couplings, polished rod couplings and sub-coupling
§ Sucker rod couplings has same box thread size in both end.
§ The polished couplings are 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 end.
· All of the three types have two classes: class T and class SM.
§ The class T stands for Through-hardened.
§ The class SM stands for sprayed metal.
· The outer diameter of the sucker rod couplings has full size and slim hole types.
