Oil Well Drilling Class T And SM Sucker Rod Coupling As Per API 11B/ Polished Rod Coupling
Oil Well Drilling Class T And SM Sucker Rod Coupling As Per API 11B/Polished Rod Coupling
Description of sucker rod coupling:
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.
