關鍵字 casing and liner pipe

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 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. Gas Seal Test: Passed the gas seal tests of Xi’an CNPC Tubular Goods Research Institute. Corrosion Detection Test in Yuanba Gas Field (Xi’an Maurer Petroleum Engineering Laboratory) The website of product detail: http://tft-intl.com/?lang=en
