耐磨陶瓷复合管Wear resistant ceramic composite pipe

耐磨陶瓷复合管充分发挥了钢管强度高、韧性好、耐冲击、焊接性能好以及刚玉陶瓷高硬度、高耐磨、耐蚀、耐热。因此,复合管具有良好的耐磨、耐热、耐蚀以及抗机械冲击与热冲击、可焊接等综合性能。是输送颗粒物料、磨削、腐蚀性介质等理想的耐磨、耐蚀管道。广泛用于电力、矿山、钢铁、水泥、化工等行业。型号有直管、弯头、弯管、三通、大小头,另外可以生产裤衩管,使用效果十分理想。可替代合金管、铸铁管等。

陶瓷复合管特点

1.耐磨性好

陶瓷复合管由于内衬层为刚玉陶瓷,莫氏硬度可达9.0,相当于HRC90以上。因此对冶金、电力、矿山、煤炭等行业所输送的磨削性介质均具有高耐磨性。经工业运行证实:其耐磨寿命是淬火刚的十倍甚至几十倍。

2.运行阻力小

SHS陶瓷复合管由于内表面光滑、且永不锈蚀,也不像无缝钢管内表层有凸状螺旋线存在。其表面光滑度优于任何金属管道,因此该管具有运行阻力小等特点。

3.耐腐蚀、防结垢

由于该刚玉陶瓷层为(a-AL203),属中性特质。因此具有耐酸碱和耐海水腐蚀,并同时具有防垢等特性。

 

4.耐温性能与耐热冲击性能好

由于该刚玉陶瓷(a-AL203),为单一稳定的晶态组织。因此复合管可在-50700℃温度范围内长期正常运行。材料具有良好的热稳定性。

5.工程造价低

陶瓷复合管重量轻,价格适宜。比同内径的铸石管重量轻50%,比耐磨合金管重量轻20%-30%,且耐磨、耐蚀性好,因为使用寿命长,从而支吊架费用、搬运费、安装费以及运行费用降低。

 

6.安装施工方便

由于该管重量轻,且焊接性能好。因此可采用焊接、法兰、快速联结等方式,施工安装方便。

 The wear-resisting ceramic clad pipes give full play to the high strength, toughness, impact resistance, good welding performance, high hardness, high wear resistance, corrosion resistance and heat resistance of corundum ceramics. Therefore, the composite pipe has good wear resistance, heat resistance, corrosion resistance, mechanical and thermal shock resistance, weldability and other comprehensive properties. It is an ideal wear resistant and corrosion resistant pipeline for conveying granular materials, grinding and corrosive media. It is widely used in power, mining, steel, cement, chemical industry and other industries. The model has straight pipe, elbow, elbow, tee, size head, in addition to the production of trousers pipe, the use effect is very ideal. It can replace alloy pipe, cast iron pipe and so on.
Characteristics of ceramic composite pipes
1. good wear resistance.
The ceramic composite pipe is made of corundum ceramics because of the inner liner, and the Mohs hardness can reach 9, which is equivalent to HRC90. Therefore, the grinding media conveyed by metallurgy, power, mining, coal and other industries have high wear resistance. It has been proved by industrial operation that its wear life is ten times or even tens of times of quenching rigidity.
2. running resistance is small.
SHS ceramic clad pipes are smooth and never corroded, and they do not exist as convex spirals in the inner surface of seamless pipes. Its surface smoothness is better than any metal pipe, so the tube has the characteristics of small running resistance.
3. corrosion resistance and scaling prevention
Because the corundum ceramic layer is (a-AL203), it belongs to the neutral character. Therefore, it has the characteristics of acid and alkali resistance and seawater corrosion resistance as well as scale prevention.

4. temperature resistance and heat shock resistance are good.
The corundum ceramic (a-AL203) is a single stable crystalline structure. Therefore, the composite pipe can run normally for a long time at the temperature range of -50 - 700 C. The material has good thermal stability.
5. low construction cost
Ceramic composite pipes are light in weight and suitable for price. It is 50% lighter than the cast stone pipe with the same inner diameter, 20% - 30% lighter than the wear resistant alloy pipe, and has good wear resistance and corrosion resistance. Because of its long service life, the cost of support and hanger, transportation, installation and operation is reduced.

6. installation and construction convenience
Because the tube is light in weight and weldability is good. Therefore, welding, flange and quick connection can be used for construction and installation.
