The sucker rod couplings are used for connecting sucker rods, polished rods and sinker bars.\u00a0
\u00a0-The main types of sucker rod couplings are sucker rod couplings, polished rod couplings and sub-couplings.
– All of the 3 types have 2 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″
\u00a0
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.
\u00a0
\u00a0<\/strong>Class T<\/strong> 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.<\/p>\n

Production<\/strong><\/p>\n

    \n
  • The sucker rod couplings are manufactured in their own dedicated line.<\/li>\n
  • Cleaned \u2192 prepared \u2192 loaded on mandrels \u2192 shot blasted \u2192 flame sprayed \u2192 induction fused.<\/li>\n
  • The flame spray process is a computer controlled, menu driven operation that holds spray application<\/li>\n
  • tolerance to within 2 thousandths of an inch.<\/li>\n<\/ul>\n

    Classification<\/p>\n

      \n
    • The main types of sucker rod couplings are sucker rod couplings, polished rod couplings and sub-couplings.<\/li>\n
    • Sucker rod couplings has same box thread size in both end.<\/li>\n
    • The polished couplings are designed to connecting polished rod and sinker bars.<\/li>\n
    • The sub-coupling is also called cross over coupling. It has different box thread sizein both end.<\/li>\n<\/ul>\n
        \n
      • All of the 3 types have 2 classes: class T and class SM.<\/li>\n
      • The class T stands for Through-hardened.<\/li>\n
      • The class SM stands for sprayed metal.<\/li>\n
      • The outer diameter of the sucker rod couplings has full size and slim hole types.<\/li>\n
      • According to the surface of the suck rod couplings, it can be divided into smooth surface suck rod couplings and suck rod couplings with 2 wrench square<\/li>\n
