Guan County in Shandong Huayu Power Equipment Co., Ltd. is the high-tech enterprises in Shandong Province, the company is located in northern China Shuicheng - Liaocheng. Companies adhere to the principles of technology and development, quality of survival, to provide customers with first-class products and quality service. Main products: 1, ceramic-lined composite pipe, wear-resistant ceramic elbow, wear-resistant ceramic mosaic ceramic wear elbow, wear-resistant ceramic chip, wear-resistant ceramic pipes, wear size head, ceramic lined elbow ceramic composite pipe, ceramic lined pipe, wear-resistant ceramic links, and automatic compensation between ceramic wear a variety of Pipes, two, double plate wear-resistant ceramic valves. Guan County Arima electricity production lined pipe ceramic wear characteristics: 1, good wear resistance due to the ceramic composite pipe lining 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 high abrasion resistance. Confirmed by the industrial operation: its hardened steel wear life is ten times or even several times. ? 2, running resistance? SHS ceramic composite pipe due to smooth inner surface, and never rust, nor as seamless steel pipe inner surface convex spiral exists. After internal surface roughness of the test units and water resistance characteristics of the test, the inner surface smoothness superior to 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? Because the steel ceramic layer (a-AL2O3), a neutral character. So with acid and sea water resistant, and also has anti-fouling properties. ? 4, heat resistance and good thermal performance punch Fou? Since the corundum ceramics (a-AL2O3), a single stable crystal structure. Therefore, long-term composite pipe running within -50--700 ℃ temperature range. Linear expansion coefficient of 6-8 × 10-6 / 0C, around about 1/2 of the steel pipe. Material has good thermal stability. ? 5, low construction cost? Ceramic composite tube light weight, affordable. Lighter than cast stone pipe with an inner diameter of 50% by weight; 20-30% lighter weight than the wear-resistant alloy tube, and wear and corrosion resistance, long life because so hanger fees, handling fees, installation fees and reduce operating costs. By the relevant design institutes and construction unit project budget and compare actual engineering, construction cost of the pipe and cast stone fairly, compared with the wear-resistant alloy tube, down about 20 percent of project cost. ? 6, installation easy? Because of its light weight of the tube, and good weldability. So can weld, flanged, quick links, etc., to facilitate the construction and installation, and can reduce installation costs. 7. Other knowledge ceramic pipe with traditional steel, wear-resistant alloy steel pipe, cast pipe and steel-plastic, steel pipe and other rubber has essential difference. Ceramic outer layer is steel pipe inner corundum. Corundum layer up to 100-1500 Vickers hardness (Rockwell hardness of 90-98), the equivalent of tungsten-cobalt hard gold. High wear resistance than carbon steel pipe more than 20 times, it is much more superior than the usual adhesive wheel made of corundum performance. Now is still a variety of corundum grinding wheel grinder cut hardened steel main wheel. Ceramic pipe layer in the corundum corundum grinding wheel wear out. Wear-resistant ceramic pipe corundum mainly by a few millimeters thick inner layer, the Mohs hardness of 9, second only to diamond and silicon carbide, oxide in all, it is the highest hardness. Wear-resistant ceramic lined steel pipe is the use of self-propagating high-temperature synthesis - Manufacturing centrifugation, the melting point of alumina ceramic pipe in 2045 ℃, alumina layer and the steel layer structure due to process special reasons, the stress field is also special. At room temperature ceramic layer compressive stress, tensile stress by steel layer, the two opposites, into a balanced whole. Only the temperature rises above 400 ℃, both due to the thermal expansion coefficient is not the same, the new stress field generated by the thermal expansion of the ceramic and steel in the presence of the original stress field cancel each other, so that both the ceramic layer and the steel layer is in free equilibrium. When the temperature rises to 900 ℃ to wear-resistant ceramic lined steel pipe placed in the water Ling, repeated immersion times, the composite layer does not crack or split, showing ordinary ceramic unparalleled thermal shock resistance. This performance in the construction of great use, because of its outer layer is made of steel, coupled with the inner temperature does not crack in the construction of the flange, purge port, explosion-proof doors can be welded directly to the welding method can also be used connection, than wear and cast stone pipe, wear steel pipe, wear-resistant steel rare, double metal composite pipe, steel pipe, steel rubber tube in the construction can not be easily welded or soldered better. Lined pipe ceramic wear resistance to mechanical shock resistance or, in between the transportation, installation and beat two brackets weight bending deformation, not broken off the composite layer. Currently, dozens of thermal power plants proved that: wear-resistant ceramic lined steel pipe high wear resistance, anti-erosion ability fluid. In a wind pipe, pipe wear fastest, wear-resistant ceramic lined steel pipe elbow thick abrasion wear resistance than steel elbow more than 5 times. In practice, wear-resistant ceramic lined steel pipe 1-2 years after the opening to observe and measure, the composite layer had no significant wear or loss, in the same piping specifications and terms of unit length, lined with ceramic wear resistant steel weighs only steel tube mill or bimetallic composite pipe about 1/2 of its construction cost per meter lower by 30-40%, only about cast stone pipes and wear-resistant steel weight RE 2/5 per meter reduced by more than 20% of project cost . Lined with ceramic wear steel in corrosive or high temperatures used, the price is only stainless steel pipe, a fraction of the nickel-titanium tube. Fluid pipeline not only used in the power industry, but throughout the metallurgy, coal, petroleum, chemicals, building materials, machinery and other industries. When transporting large grinding pipe materials (such as ash, coal, mineral powder, tailings cement, etc.), there is a pipe wear faster problem, especially fast bends wear; when the pipeline transportation has strongly corrosive gases, liquids or solids, are present so as to be quickly corroded pipeline damage problem; when the pipeline transporting material having a higher temperature, there is a heat resistant steel is very expensive problems. Second, the application:? 1, metallurgy, electric power industry application in metallurgy, electric power industry, transport coal, ash, mud, lime and gypsum slurry, etc. need to consume a large amount of metal pipes each year. Ceramic composite pipes to replace the other channels, with high wear resistance, long life, easy installation, with significant economic benefits characteristics. Run Power Plant in Shandong Liaocheng, China Liaocheng plant, Beijing New Building Materials Group, Henan Hebi power plants, Pingliang Power Plant, Taiyuan Coal, Hunan Shimen Power Plant, Hebei Jinniu Energy Co. Gequan Coal, Xingtai Coal other industrial operation, the operating life is a steel pipe more than ten times or even several times. ? 2, mining, coal industry in the application (1) Mining:? Mine filling, powder concentrate and tailings pipeline transporting serious wear, slag pipelines used in the past such as Panzhihua, Daye ore than life a year, instead of the tube can improve the life of about five times. ? (2) coal: coal and long-distance pipelines transporting coal generally wet, wear and they both require delivery pipe corrosion, the use of the pipe as longevity pipeline, economic benefits. ? 3, the other? (1) does not pollute and stick the tube linking the molten aluminum. Manufacture of iron contamination sensitive, and the need to use heavy labor after finishing and repair equipment molten aluminum, aluminum liquid pipeline, riser tubes is the ideal material. ? (2) of the tube due to heat and corrosion and wear resistance. For conveying solid particles containing corrosive materials and high-temperature corrosive gases, sulfur geothermal water and other corrosive media. ?
