Wear-resistant ceramic-lined composite pipe performance which?

Wear-resistant ceramic lining composite pipe using the main technology is the centrifugal casting composite ceramic technology. This technology is mainly used in the processing of ceramics is a high-temperature technology, in the conditions of high temperature in the elbow out of a layer of fine and uniform wear-resistant ceramic, wear-resistant lining ceramic composite pipe cast ceramic and Steel pipe to form an integrated structure, so when we use this wear-resistant ceramic elbow inside the ceramic and outside things are one, even if the use of a long time do not have to worry about the ceramic layer off.
Wear-resistant ceramic-lined composite pipe performance which?
1 Physical and mechanical properties
The self-propagating technology makes the ceramic composite steel pipe has a unique structure, which determines the excellent mechanical and mechanical properties of ceramic pipe, which not only wear resistance, corrosion resistance, high temperature, but also high hardness, strength and good resistance to mechanical shock and Thermal shock of the comprehensive performance.
2 excellent wear resistance
Ceramic-lined composite pipe with the traditional steel pipe, wear-resistant alloy steel pipe, steel tube, etc. have a fundamental difference. Ceramic steel pipe is the outer layer, the inner layer is dense a type of aluminum oxide (corundum). Corundum layer Vickers hardness of up to 1100-1500 (Rockwell hardness of 90-98), equivalent to tungsten cobalt cemented carbide. Wear resistance than carbon steel pipe is more than 20 times higher than it is usually bonded corundum grinding wheel performance is much better ceramic wear resistance is mainly by the inner layer of corundum layer, the Mohs hardness of 9, second only to Diamond and silicon carbide
3 excellent corrosion resistance
Ceramic tube containing more than 90% of aluminum oxide, aluminum oxide is neutral oxide, and acid, alkali, salt, not from the chemical reaction, acidity 96-98%, with high corundum porcelain acidity, At the same time, aluminum oxide is an inorganic substance, in the light, heat, oxygen and other natural environment long-term effect, there is no deterioration (ie, aging) problem. Ceramic layer can be acid, alkali and electrochemical corrosion, the determination of ceramic pipe corrosion resistance than stainless steel ten times.
4 running resistance is small
Ceramic-lined steel pipe as the inner surface of the smooth, and will never corrosion, nor as the surface of the seamless spiral pipe convex convex, the authority of the unit running ash resistance test, the water resistance coefficient of 0.0193, drag coefficient is less than ordinary steel pipe, Can reduce pipeline running resistance, reduce operating costs.
5 anti-fouling performance and reliable
6 high mechanical impact resistance
Is a professional manufacturer of ceramic wear-resistant products series of high-tech enterprises, focusing on industrial anti-wear technology research and development and application, the main production wear-resistant ceramic pipes, ceramic composite pipe, ceramic patch pipe, ceramic lined composite pipe, Ceramic elbow, self-propagating ceramic composite pipe, steel pipe lined with ceramic, wear-resistant ceramic pipe, wear-resistant ceramic, wear-resistant ceramic liner, wear-resistant ceramic shaped parts, wear-resistant ceramic products are widely used in thermal power, steel, cement , Smelting, coal, mining, chemical, port and other industries wear serious equipment.


 
耐磨内衬陶瓷复合管使用的主要技术就是离心浇铸复合陶瓷技术。这种技术加工出来的陶瓷主要使用的是一种高温技术,在高温的条件下在弯头的内部浇灌出来一层细致而且均匀的耐磨的陶瓷,耐磨内衬陶瓷复合管浇铸出来陶瓷与钢管形成一体化的结构,所以在我们使用这种耐磨陶瓷弯头的时候里面的陶瓷和外面的东西都是一体的,即便是使用的时间比较长也不用担心陶瓷层脱落。
 
耐磨陶瓷内衬复合管的性能有哪些?
1物理机械性能
自蔓延技术使陶瓷复合钢管具有独特的组织结构,该结构决定了陶瓷钢管优良的物理机械性能,它不但抗磨损、耐腐蚀、耐高温,而且有高的硬度、强度和良好的抗机械冲击和热冲击的综合性能。
2耐磨性能卓越
陶瓷内衬复合管与传统的钢管、耐磨合金铸钢管、钢橡管等有着本质性区别。陶瓷钢管外层是钢管,内层是致密a型三氧化二铝(刚玉)。刚玉层维氏硬度高达1100—1500(洛氏硬度为90—98),相当于钨钴硬质合金。耐磨性比碳钢管高20倍以上,它比通常粘接而成的刚玉砂轮性能优越得多,陶瓷钢管抗磨性主要是靠内层的刚玉层,其莫氏硬度为9,仅次于金刚石和碳化硅
3耐蚀性能优良
陶瓷管含a型三氧化二铝90%以上,三氧化二铝属中性氧化物,与酸、碱、盐均不起化学反应,耐酸度96-98%,同高刚玉瓷耐酸度相当,同时,三氧化二铝是无机物质,在光、热、氧等自然环境长期作用下,不存在变坏(即老化)的问题。陶瓷层可耐酸、碱及电化学腐蚀,经测定陶瓷钢管耐蚀性比不锈钢高十倍。
4运行阻力小
陶瓷内衬钢管由于内表面光滑,且永远不会腐蚀,也不像无缝钢管内表面凸状螺旋线存在,经权威单位运行输灰阻力测试,清水阻力系数为0.0193,阻力系数小于普通钢管,可降低管线运行阻力,减少运行费用。
5抗结垢性能可靠
6抗机械冲击性能高
公司是一家专业制造陶瓷耐磨系列制品的高科技企业,专注于工业防磨技术的研发和应用,主要生产耐磨陶瓷管道,陶瓷复合钢管,陶瓷贴片管道,陶瓷内衬复合管,耐磨陶瓷弯头、自蔓延陶瓷复合管、钢管内衬陶瓷、耐磨陶瓷钢管、耐磨陶瓷片、耐磨陶瓷衬板、耐磨陶瓷异形件、耐磨陶瓷,产品广泛应用在火电、钢铁、水泥、冶炼、煤炭、矿山、化工、港口等行业磨损严重的设备上。
