SHS自燃烧陶瓷复合管的特点

自蔓延高温合成技术的鲤儒陶瓷复合钢管是，即“世纪”技术综合，是全国高科技“863”项目，是原有的国家冶金行业部门，电力项目的专注于促进新产品，由陶瓷（刚玉）层，过渡层和钢层组成的三个部分。

耐磨性好

Ceramic composite pipe due to corundum ceramic (a-AL2O3), Mohs hardness of 9.0 is equivalent to more than HRC90. Therefore, it has high wear resistance for abrasive media conveyed by industries such as metallurgy, electric power, mining, and coal. It has been confirmed by industrial operation that its wear life is ten times or even several ten times that of hardened steel.

Small operating resistance

SHS陶瓷复合管道不像无缝钢管内表面上的凸螺旋线，因为内表面是光滑的，永不腐蚀。测试相关测试单元的内表面粗糙度和透明耐水性特性。内表面的平滑度优于任何金属管。透明的阻力系数为0.0193，略低于无缝管。因此，管具有小的运行阻力的特点，可以降低运营成本。

Corrosion, anti-scaling

由于钢陶瓷层是（A-Al2O3），因此是中性特性。因此，它耐酸和碱和海水腐蚀，它也具有反缩放性质。

Temperature resistance and heat resistance

Due to the corundum ceramic (a-AL2O3), it is a single stable crystalline structure. Therefore, the composite pipe can operate normally in the long-term temperature range of -50--700°C. Material linear expansion coefficient of 6-8 × 10-6/0C, about 1/2 of the steel pipe. The material has good thermal stability.

该项目的成本很低

陶瓷复合管重量轻，实惠。它比具有相同内径相同的铸石管的50％;它比耐磨合金管轻20-30％，由于其使用寿命长，因此具有良好的耐磨性和耐腐蚀性，从而支撑衣架成本，运输成本，安装费和降低运营成本。将设计学院和建筑单位的项目预算与实际项目进行比较，项目成本相当于铸造石。与耐磨合金管相比，项目成本降低约20％。

易于安装和施工

Because of its light weight and good welding performance. Therefore, welding, flanges, quick coupling, etc. can be adopted, and the construction and installation are convenient, and the installation cost can be reduced.

其他知识

陶瓷钢管和传统钢管，耐磨合金铸钢管，铸造石管，钢塑料，钢橡胶管等具有必要的差异。陶瓷钢管的外层是钢，内部是刚玉。刚玉层的维氏硬度高达100-1500（罗克韦尔硬度为90-98），这相当于钨钴硬金。耐磨性比碳钢管高出20倍，它优于通常粘合的刚玉研磨轮。现在刚玉砂轮仍然是研磨机的主砂轮。陶瓷钢管中的刚玉层可以磨损刚玉砂轮。陶瓷钢管的耐磨性主要由几毫米厚的刚玉层的内层，其摩尔斯硬度为9，仅在所有氧化物中均为金刚石和SiC，其硬度最高。

内衬陶瓷耐磨钢管由SHS高温合成离心方法制造，岩磺钢管中熔点为2045℃，刚玉层和钢层具有特殊的结构和应力场，因为工艺原因。在常温下，陶瓷层的压缩应力，钢层的拉伸应力，两个对立面，进入平衡的整体。只有当温度上升到400℃以上时，由于热膨胀系数是不同的，由于陶瓷钢管中的热膨胀和原始应力场产生的新应力场彼此抵消，因此陶瓷层和陶瓷层钢层处于自由平衡状态。当温度升至900℃的内衬陶瓷耐磨钢管进入水中时，反复反复浸泡，复合层不裂开或开裂，显示出普通陶瓷的无与伦比的热抗震性。这种性能在施工方面很有用，因为外层是钢，除了加热内层没有破裂，在施工中，法兰，吹，防爆门可以焊接，也可以直接焊接连接，这不仅仅是耐磨铸造石管，耐磨铸钢管，稀土耐磨钢管，双金属复合管，钢管，钢管，钢管管施工不易焊接或焊接不仅仅是芯片。内部衬垫陶瓷耐磨钢管耐机械冲击良好，在运输，安装搏动和两个支撑重量弯曲变形之间，复合层不会断开。

At present, the practice of dozens of thermal power plants shows that the wear resistance of the inner-lined ceramic steel tube is high, and the resistance to fluid scouring is strong. In the first air duct, the bending pipe wear the most quickly, the wear resistance of the inner liner ceramic wear-resisting steel pipe is more than 5 times times higher than that of the thick wall wear-resisting cast steel elbow.

在实践中，内衬陶瓷耐磨钢管1-2岁以打开观察和测量，复合层没有明显的磨损或脱落，在相同的尺寸和单位长度的管道，内部衬里陶瓷磨损-Resistant钢管重只有耐磨铸钢管或双金属复合管约1/2，每米的成本减少30-40％，仅铸造石管和稀土耐磨钢管重量大约2/5，每米项目成本降低超过20％。在腐蚀性或高温场所使用衬里陶瓷耐磨钢管，其价格只是不锈钢管，镍钛管的一小部分。

Fluid pipeline transportation is not only used in the power industry, but also in metallurgy, coal, petroleum, chemical, building materials, machinery and other industries. When the pipe is transported with large grinding material (such as ash residue, pulverized coal, mineral fine powder, tailings cement, etc., there is a problem of fast abrasion of pipe, especially the bending pipe wear fast; when conveying a strong corrosive gas, liquid or solid in the pipeline, there is a problem that the pipeline is corroded and destroyed quickly. When conveying the material with high temperature in the pipeline, there are some problems such as the price of heat-resisting steel pipe is very expensive. The internal liner ceramic wear-resistant steel pipe market, these problems are solved.
