耐磨铸石管：1、耐磨性：陶瓷复合钢管的内衬陶瓷层中Al2O3含量大于90％，显微硬度HV1000－1600，密度3.8－3.97g/cm3，因而具有极高的耐磨性，其耐磨性比淬火后的中碳钢高十倍，优于钨钻硬质合金。2、耐腐蚀性陶瓷属中性材料，化学性能稳定，具有优异的耐腐性和耐酸性，可抗各种无机酸、有机酸、有机溶剂等，其抗蚀程度是不锈钢的十倍以上。3、耐热性陶瓷层属致密刚玉，其线膨胀系数为6－8×10-6/℃。耐热性能优异，能耐温2000℃以上，可在-50℃～900℃范围内长期工作。4、机械性能：具有优良的机械性能，其压溃强度300－600MPa，压剪强度20－30MPa，抗机械冲击试验在50t能量冲击下15次无明显裂纹。5、易焊接：陶瓷内衬复合钢管可以通过焊接外层钢管达到连接的目的。6、运输安装方便：陶瓷复合钢管与钢管、耐磨合金铸管、铸铁管和铸石管比较，相对重量轻，便于运输和安装。

Wear resistance and wear resistance of cast stone pipe: 1: Al2O3 content of ceramic liner composite pipe in more than 90%, hardness HV1000 1600, density 3.8 3.97g/cm3, so it has high wear resistance, the wear resistance of quenched steel than ten times higher than that of tungsten carbide. 2, corrosion resistant ceramics belong to neutral materials, chemical stability, excellent corrosion resistance and acid resistance, can resist all kinds of inorganic acids, organic acids, organic solvents, etc., and its corrosion resistance is more than ten times of stainless steel. 3. The heat resistant ceramic layer belongs to compact corundum, whose coefficient of linear expansion is 6-8 x 10-6/ centigrade. It has excellent heat resistance and can work over 2000 degrees centigrade. It can work for a long time in the range of -50 ~ 900 centigrade. 4, mechanical properties: with excellent mechanical properties, its crushing strength 300 - 600MPa, compressive shear strength 20 - 30MPa, mechanical impact test under 50t energy shock 15 times no obvious crack. 5, easy welding: ceramic lined composite steel pipe can be welded to achieve the purpose of connecting the outer steel tube. 6, convenient transportation and installation of steel pipe and steel pipe, ceramic composite wear-resistant alloy pipes, cast iron pipes and tubes, relatively light weight, convenient transportation and installation.
