1. Features:

Effectively improved the corrosion resistance;

Effectively improved the eccentric wear resistance;

The amorphous tungsten alloy on the surface is of high strength (the yield strength and tensile strength are both higher than 2Gpa)

and without

cracks, which enable the fatigue life of sucker rods to be greatly improved - to work more than one million times in corrosive environment!

 2. Structure

There is deposition of tungsten alloy layer on the outer surface of API standard sucker rods, and there is protection for threads

at the both ends.

 

 

 3. Performance Indicators:

Mechanical Property: The backing material meets API Standards

Corrosion Property: Resistance to H2S/CO2 corrosion in high temperature, salt water corrosion, alkali corrosion and weak acid

corrosion, meeting the corrosion resistance requirements of NACE 0177 Standards.

Wear Resistance: Good, equivalent to that of hard chromium layer.

Tungsten Alloy Layer and Backing Material Binding Force: According to GB/T5270-2005 testing, the

 plating layer does not crack or peel off.

Appearance: Uniformly bright, showing silvery white.

Thickness of Tungsten Alloy Layer: 30-50μm

 4. Performance Testing

Wear and Corrosion Resistance Test: Passed a variety of the wear and corrosion resistance test carried out by

Xi'an CNPC Tubular Goods Research Institute, Xi’an Maurer Petroleum Engineering Laboratory, and Quality Supervision

and Inspection Center of Surface Covering Layer Products for Machinery Industry.

Mechanical Property Testing: Passed the testing of Quality Supervision and Inspection Center for National Oil

And Gas Wellhead Equipment

Testing of cracking Caused by Hydrogen Sulfide Corrosion and Stress (Xi’an Maurer Petroleum

 Engineering Laboratory)
