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

Ceramic lined pipe elbows

Ceramic - lined pipe  is the use of SHS – Manufacturing centrifugation, the melting point of alumina  ceramic  pipe in 2045 ℃, alumina layer and the steel layer

Ceramic Tile Lined Bend

Ceramic tile lined bending have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface. It is well understood that conveying velocity of ash, its density as well as size of ash particles are major factors that determine wear rate of Bends and Y-Pieces. Here, the use of Alumina Ceramic in Ash Handling systems help in lowering the possibility of wear and damages caused to the internals. Here, our expertise lies in filling the linings in casings manufactured at our works or can also be fitted directly in worn out volute casing at plant site. Well package of Alumina Ceramic Lined Bends Some of the industry areas where these are used include: Coal Fired Thermal Power Projects Mineral processing units Steel Plants Cement Plants Coal and Mineral washeries Aluminium plants

Large diameter ceramic lined tile pipe

  The Ceramic tile lined pipe spool is composed by steel pipe, adhensive and abrasion-resistant ceramic, we use 20 # seamless steel pipes shaping with hot bending (it is different from centrifugal casting or steel plate rolling), the ceramic tiles bonding with GWJ-350 high temperature-resistant inorganic adhesive which was developed by TsingHua University and affix abrasion-resistant ceramic in the steel pipes, we use miss match installation instead of directly bonding (this technology was used in the bridge building a thousand years ago), and forms a firm wear-resistance layer after heating solidification. Ceramic tile lined pipe spool is applicable for the pneumatic powder-feeding, and can be used under a temperature of 350℃without aging and peeling for long life. The service life is 4-5 times than the normal abrasion-resistant pipes. Advantage Super wear-resistant, high density: we use 95% of chromium corundum, 100 tons dry-pressing.

Cast basalt lined steel pipe

Cast basalt lined steel pipe is consist of steel pipe, cast basalt pipe and the concreteness of cement mortar. The excellent performance of cast basalt lined steel pipe is that it sets tenacity of steel pipe, abrasive resistance of cast basalt pipe, concreteness of cement mortar in one. After 30 years of practical use proved cast basalt lined steel pipe is a reliable and effective combination of wear—resistant materials. Be used in a variety of transportation of corrosive materials in working condition. This greatly improves the products adaptive capacity in complicated operation conditions. At the same time. cement mortar is selected as the filling material and this can make the inside surface of steel pipe in alkali mediums. So the surface of steel pipe generates purifying films. These films can prevent being rusted. Flange connection is one kind of common pipeline installation connections. The parameters of the outside steel pipe will be decided according to the working pressure of ...

Wear resistant alumina ceramic rings
