Wear-resistant ceramic elbow

Self-propagating ceramic composite pipe full play due to high steel strength, toughness, impact resistance, good weldability and corundum high hardness, high wear resistance, corrosion resistance, heat resistance, and to overcome the low steel hardness, wear resistance and poor Ceramic poor toughness characteristics. Thus, self-propagating ceramic composite pipe has good wear, heat, corrosion and resistance to mechanical shock and thermal shock, and good weldability overall performance. Is wear and corrosion pipeline ideal particulate material, grinding, and other corrosive media. Since the spread of the performance characteristics of the ceramic composite pipe: 1, wear self-propagating ceramic composite pipe liner due corundum ceramics (a-AL2O3), Mohs hardness of up to 9.0 equivalent of HRC90 or more. Therefore, metallurgy, electric power, mining, coal transportation and other industries grinding media have a high abrasion resistance. 2, running resistance of small self-propagating ceramic composite pipe due to the smooth inner surface, and never rust, nor as seamless steel pipe inner surface having a convex spiral exists. After testing the inner surface roughness and water resistance characteristics of the test, the inner surface smoothness better than any metal pipe, clear the drag coefficient of 0.0193, slightly lower than seamless. Therefore, the tube has a running resistance and other characteristics, can reduce operating costs. 3, corrosion resistance, anti-fouling self-propagating ceramic composite steel tube since the ceramic layer (a-AL2O3), is a neutral character. So with acid and resistance to seawater corrosion, and also has anti-fouling properties. 4, heat resistance and thermal performance good punch from spreading pottery ceramic composite tube since the corundum ceramics (a-AL2O3), a single stable crystal structure. So that the composite tube long-term normal operation within -50--700 ℃ temperature range. Linear expansion coefficient of 6-8 × 10-6 / 0C, around about 1/2 of steel. Material has good thermal stability. Rhea Guan County in Shandong Power Equipment Co., Ltd.
