Product Description

Product Description

Polished Rod

1. Introduction:   
Polished rods are designed for connecting sucker rod strings to beam pumping units via polished rod packing. The rods are round cross-section bars.
We provide three  types of polished rods: normal polished rod, polished rod-metal spray and polished rod-upset on one end.
2. Characteristics:
1) Designed in accordance with API standards; 
2) Manufactured through cold-drawing, rolled threading, and surface grinding, etc. 
3) Has high strength, good toughness, smooth surface and long lifetime, etc.

Polished Rod Coupling
Polished rod couplings are designed for connecting of the polished rod to the top rod of the string. Contrary to rod couplings, polished rod couplings have a female cone that eliminates the coupling twist-off in the course of operation.
1. Standard: API Spec 11B
2. Materials: AISI5140 (high quality carbon steel)
3. Coat thickness: 0.010in-0.020in
4.  Coat Material: Ni60A Alloy Coating
5. Classification: full size and slim hole
6. Coupling diameter: 5/8"; 3/4"; 7/8"; 1"; 1-1/8"
7. New product: Two-way globoidal protection sucker rod coupling;
               Full size sucker rod coupling with big chamfer


Polished Rod Clamps
Our polished rod clamps are forged from high-grade heat-treated steel, and they can hold the heaviest rod string in rod pump and PC pump applications. The clamping surface is drilled and reamed to the exact size of the polished rod. In addition, the contact areas are spaced apart to provide maximum clamping effect. If the hanger bar is flat, both ends are squared with the hole to prevent eccentric loads.
