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
Performance
Testing
Wear and Corrosion Resistance Test:
Having passed a variety of the wear and corrosion resistance tests
carried out by Xian CNPC Tubular Goods Research Institute, Xian
Maurer Petroleum Engineering Laboratory, and Quality Supervision
and Inspection Center of Surface Covering Layer Products for
Machinery Industry.
Mechanical Property Test: Having passed the tests of National Oil Field Wellhead Equipment Inspection Center.
