Product Description

API 11B 7/8” Sucker Rods CouplingsThe 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 ;The coupling blanks are formed or machined to size and tolerance, threaded using a cold-forming rolled thread tap and coated for anti-galling and lubrication properties.Class T couplings are recommended for installation where abrasion or corrosion-abrasion is not a problem.Class SM couplings are recommended for abration or corrosion-abration position.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-couplings.
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 sizein 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.
According to the surface of the suck rod couplings, it can be divided into smooth surface suck rod couplings and suck rod couplings with two wrench square
