The ceramic-lined steel pipe is a kind of ceramic and metal organic combining composite pipe, ceramic tube is a combination of alumina the advantages of high hardness, good chemical inertness and steel, excellent wear resistance, corrosion resistance, heat resistance and thermal shock and mechanical shock resistance.
1, abrasion resistance, ceramic composite steel pipe lined with porcelain layer of Al2O3 content is more than 95%, micro hardness HV1000-1500, and therefore has a very high wear resistance, its wear resistance more than 10 times higher than the medium carbon steel after quenching and is better than that of tungsten carbide drill.
2, the corrosion resistance of ceramics is a neutral material, stable chemical performance, excellent corrosion resistance and acid resistance, can resist various inorganic acid, organic acid, organic solvents, such as its resistance to corrosion is stainless steel is more than ten times.
3, heat-resisting performance, can heat resistance above 2000 ℃, can be in - 50 ℃ ~ 900 ℃ within the scope of work for a long time.
4, easy to welding: the ceramic-lined steel composite pipes can be achieved through the outer steel tube welding connection, the purpose of the ceramic-lined steel composite pipes can be connected by welding, flange, such as flexible quick connectors, installation is very convenient.
1. High wear-resisting pipe: thermal power, thermal power plant pulverized coal ash slag () transmission, pipeline, concentrator tailings conveying pipeline, and concentrate port pulp and sediment pipeline, pulverized coal slurry pipeline, etc.
2. Heavy media select (wash) coal plant coal conveying pipeline, requiring high corrosion resistance thermal power generation desulfurization slurry transport pipeline.
3. Molten aluminum liquid transport pipeline.
4. High wear resistance, high corrosion resistance and high temperature resistance.
