Anti- Eccentric Wear Sukcer Rod Coupling

The surface treatment includes black coating, phosphating or per the customers' requirments. Besides, it has good anticorrosion and anti-friction property.

Product Description

Introduction

We have advanced technology, in particular, a two-way protection againsteccentric wear pumping coupling of anti-wear alloy coating technology, a world leader.

Sucker rod coupling is one of our flagship products. One sucker rod coupling must be processed by a few fabrication procedures, such as, Blanking, drilling hole, boring hole, milling, thread tapping, and so on. At the last step, do the surface treatment.

The surface treatment includes black coating, phosphating or per the customers' requirments. Besides, it has good anticorrosion and anti-friction property. The following table shows the related information about the sucker rod coupling.

A. See Figure C.1. b. The nominal size of the coupling is the same as the nominal size of the corresponding sucker rod. C. The small hole coupling is a coupling with a reduced outer diameter. D. For reducing couplings and small hole reducing couplings, the outer diameter and length dimensions should be determined by the maximum thread size. eE. See Figure C.2, the shape is optional by the manufacturer. F. For 1in. foot size and slim hole reducing coupling L=4.500in.(114.3mm) G. For 1 1/8in. foot size reducing coupling L=5.000in.(127.0mm)
