Cangzhou Boyang Pipeline Equipment Manufacturing Co., Ltd. of KMTBCr28 bimetallic wear resistant pipe with good wear resistance and weldability becoming reliable power, steel, chemical, metallurgical and other industries material handling system is more reliable anti-wear solutions described as follows: a, KMTBCr28 bimetallic wearable About RE resistant steel pipes, high chromium cast iron pipes and other single-metal wear and hardness of steel welded directly affect performance, in order to properly use and install only reduce the hardness, so its hardness only can HRC40 below, however, it is still far from ideal weldability, prone to cracking during welding. For high wear resistance, weldability, corrosion to find a balance between the impact resistance, KMTBCr28 bimetallic composite wear-resistant pipe emerged since the late 1990s, has been widely used. KMTBCr28 bimetallic composite pipe elbow can guarantee toughness, weldability and strength (compressive strength) requirements, but also to ensure sufficient resistance to abrasion, is an ideal material handling solutions with a wear-resistant pipe. Second, the material characteristics of the alloy material, hardness and wear resistance of the best high chromium white cast iron and high quality abrasion resistant alloy steel (collectively referred to as super-hard wear-resistant alloys). High chromium cast iron is hard phase KMTBCr28 M7C3 type carbide, which hardness HV1500 ~ 1800, and thus has good wear resistance, and because of this Ka carbide rod-like structure, so that it has a high toughness. And on the basis of traditional ingredients added mixture of hard metals and boron carbide, greatly increasing the hardness and fatigue resistance of traditional products to wear better than other products. Third, the scope 1, the power industry: coal system silos, hoppers, funnel, powder feed pipe. 2, the coal industry: Coal mine coal preparation pipeline heavy, wet coal handling systems, sand backfill mining. 3, the mining industry: mining filling, conveying powder concentrate, tailings pipeline. 4, the steel industry: coke pipes, pipe mill, separator, elbow, Cone, the separation barrier. 5, the cement industry: coal transport, slag transport. 6, the machinery industry: milling plants, dust, ash system equipment lined, steel dust removal equipment lining. Fourth, the performance characteristics of a good wear resistance, hardness HRC≥56 hardness wear-resistant super alloys, with good abrasion resistance and thermal stability. 2, excellent impact resistance, metal-binding properties, thermal shock resistance KMTBCr28 bimetallic composite wear-resistant pipes, the joint surface of the two metals metallurgical bond is completely safe to use and reliable. Both the thermal expansion coefficient equivalent to expansion and contraction cracking phenomenon does not occur. Elbow wall with steel, lined with super-hardness wear-resistant alloy, the product has a high alloy products both wear and corrosion resistance properties, have high mechanical properties and high impact resistance. 3, good heat resistance, corrosion resistance, super-hard alloy substrate material has a strong heat, corrosion resistance, high temperature or corrosive environments can exhibit excellent corrosion resistance, wear resistance. In wet, corrosive media and particle erosion under the action of cross-phase, using ultra-cast hardness wear-resistant alloy used is more appropriate; and in order to abrasive wear as the main failure mode of dry working conditions, the selection of a species may be obtained by heat treatment of ultra-hard wear-resistant alloy martensitic matrix. 4, low cost composite, the wear-resistant tube with good quality and advanced technology manufacturing EPC, high yield, good product dense, uniform thickness, quality and stability. 5, transportation, installation, easy to use dual-metal composite wear-resistant pipe flange can be, quick connectors, soldering directly connected. And because the fight hit the high performance composite pipe, occurred in the piping system overhaul partial blockage, you can freely percussion, hammered, you can arbitrarily cut, unloading change, welding, installation, maintenance is very easy
