Wholesale coal yard wearable elbow | Hongyuan wear elbow wear fittings (Contact: Feng Hongmei Contact: 15,932,713,817, QQ: 1,763,757,819) ceramic composite tubes due to the inner liner of the the corundum ceramic (a-AL2O3), Mo The hardness of up to 9.0 equivalent of HRC90 more. Therefore, metallurgy, electric power, mining, coal transportation industry grinding media with high wear resistance. Industrial operation confirmed: hardened steel ten times or even several times the wear life. 2, the running resistance SHS ceramic composite pipe inner surface is smooth, and never rust, not like the seamless steel pipe inner surface of convex spiral. For detection units internal surface roughness and water resistance characteristics test, the inner surface smoothness superior to any metal pipes, Qing drag coefficient of 0.0193, slightly lower than seamless. Therefore, the tube has a small running resistance can reduce operating costs. 3, corrosion-resistant, anti-fouling due to the steel ceramic layer (a-AL2O3), is a neutral trait. Therefore have acid and seawater corrosion resistant, and also has anti-scaling and other characteristics. 4, good performance because of the corundum ceramics (a-Al2O3), as a single, stable crystalline organization. Composite pipe in a temperature range of -50 - 900 ° C for long-term normal operation. The expansion coefficient of the material lines 6-8 × 10-6/0C, approximately about 1/2 of the steel pipe. The material has a good thermal stability. The project cost light weight, low-ceramic composite pipe affordable. Than cast stone pipe of the same inside diameter to 50% lighter; 20-30% lighter than the wear-resistant alloy tube weight, and good wear resistance, corrosion resistance, because of the long service life, thus supporting the hanger fees, handling fees, installation fees and lower operating costs. Actual comparison about design institutes and construction unit project budget and engineering, and project cost of the pipe and cast stone quite compared with wear-resistant alloy tube, a decrease of 20% of project cost. 6, installation and construction convenient due to the light weight of the pipe, and welding performance. Can be welded flange, quick coupling, construction and installation, and can reduce the cost of installation. Edit this paragraph paste wearable elbow good wear resistance by Powder Metallurgy Institute of South Africa work measurement, the special ceramic wear resistance is equivalent to 266 times of manganese, 171.5 times as high chromium cast iron, excellent wear resistance. Wear elbow milling system applications greatly reduce the wear and tear of the equipment. 2 high strength and hardness was measured by the Shanghai Institute of Ceramics, Chinese Academy of Sciences, the the I produced corundum ceramic Rockwell hardness for HRA80 85, much higher than the hardness of the wear-resistant steel and stainless steel. Density is only half of the steel. Mount solid ceramic piece attached to the mother, in the process temperature above 1000 degrees, affixed to the ceramic using a short period of time will not fall off, conveying the pulverized coal pipeline to good use, and have been promoted.
