High Cr Bimetal Abrasion Resistant Pipe Elbow

The outer wall of the structure is composed of carbon steel pipe. Lining: high chromium wear-resistant alloy materials (such as KMTBCR12, chromium content from 12 to 26 or higher) , such as 16MN, 40CR, high chromium cast iron CR and CR28 series. 2. Good abrasion resistance: the high chromium wear-resistant alloy material has good abrasion resistance, the hardness HRC ≥56 of the super-hardness wear-resistant alloy has good abrasion resistance and thermal stability. Good anti-impact performance: the combination of the two metals makes the pipeline has excellent anti-impact performance, in the pipeline system maintenance occurred in the local blockage, can be knocked, hammered, and will not easily damage the pipeline structure, and can be freely cutting, unloading, welding, convenient installation and maintenance. Good comprehensive performance: not only has the high alloy casting wear resistance, but also has high mechanical strength and impact resistance, safe and reliable use. 3. The application scope is widely used in coal-fired power plant, pneumatic ash removal, slag removal, desulphurization, dust removal and other pipelines. The utility model is suitable for the pipeline under the working scene of the filling material, the coal preparation, the ore concentrate powder and the tailings transportation in the mine enterprise. It plays an important role in water-quenched slag, blast furnace coal injection, steel-making red mud, sintered white ash, dust removal pipeline and so on.
