Product Description

                                         API 11B 7/8'' Sucker Rods Couplings

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"

 
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
