Steel - high chromium wear-resistant bimetallic composite pipe
The product uses an ordinary wall seamless steel, high chrome cast steel lined composite made by centrifugal molding process to form. Hot simmer elbow bend the outer wall, the inner layer selection of high-chromium steel, high alloy steel with both wear resistance, but also pressure, have a higher mechanical properties.
1. Good overall performance. Wear-resistant composite pipe series is the use of dual-metal composite casting process, ordinary carbon steel pipe tube wall,lined with high-chromium alloy. Both have high wear resistance alloy casting, but also has high mechanical strength and impact resistance, the use of safe and reliable.
2. High wear resistance. High chromium cast hard for M7C3 type carbide, with high toughness and high hardness (HV150-180), Rockwell hardness HRC50 or more, and thus good wear resistance.
3. Strong corrosion resistance, high temperature, high wear resistance. Because Ka carbide composition and structural characteristics as well as high levels of Cr solid solution matrix has a higher heat resistance, corrosion resistance, high temperature or corrosive environments can show resistance to corrosion. In the wet state, there are corrosive media and particle erosion effect of cross-phase conditions, the use of white cast using 28Cr steel. Under dry working conditions, the choice canbe obtained by heat treatment martensitic matrix of high chromium cast steel materials.
