1. Structure: There is deposition of tungsten alloy layer on inner and outer walls of API standard pipes. Liner pipes are perforated on the casing backing material (called liner pipes after drilling), and there are deposition of tungsten alloy layer on inner and outer walls of pipes.
2.
Performance Indicators:
Mechanical Property: The pipe meets API
standards.
Anti-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.
Hardness of Tungsten Alloy Layer: ≥650HV
Tungsten Alloy Layer and Backing Material Binding Force: According to GB/T5270-2005 testing, the plating
layer does not crack or peel off.
Threaded Connection: The threads are of good resistance to thread gluing.
Appearance: Uniformly bright, showing silvery white
Thickness of Tungsten Alloy Layer: ≥60μm
3. Performance Testing Wear and Corrosion
Resistance Test: 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.
Gas Seal Test: Passed the gas seal tests
of Xian CNPC Tubular Goods Research Institute.
