UHMWPE Blue Sucker Rod Centralizer 7/8" for Oil Pumping Well
Oilfield Downholw Tools Snap-On,Circular NEPG Blue Sucker Rod Stabilizer 2-1 / 2 "X 7/8"
Description of Sucker Rod Stabilizer:
Sucker Rod Centralizer/Guide
Sucker rod centralizers or rod guides keep the rod and couplings away from the tubing to eliminate the internal tubing wear, also can keep paraffin off the tubing as paraffin scrapers. The sucker rod guides minimize costly metal-to-metal contact between the sucker rods and tubing. Even when the tubing buckles during upstrokes, the guides help prevent contact between the rods and tubing.
**Application: Rod Pumping Rod
**Standard: API 11B
**Material: Plastic, Nylon, Rubber, Steel, Aluminium
**Type: Snap-on rod guide, Twist-on rod guide, Wheeled rod guide
Sucker Rod Coupling
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”
