陶瓷复合钢管，全称陶瓷内衬复合钢管，是采用高技术生产工艺--自蔓燃高温离合合成法制造。该管从内到外分别由刚玉陶瓷、过渡层、钢三层组成，陶瓷层是在2200℃以上高温形成致密刚玉瓷（AL2O3），通过过渡层同钢管形成牢固的结合。复合管因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瓷高硬度、高耐磨、耐蚀、耐热性好，克服了钢管硬度低、耐磨性差以及陶瓷韧性差的特点。因此，复合管具有良好的耐磨、耐热、耐蚀及抗机械冲击与热冲击、可焊性好等综合性能。是输送颗粒物料、磨削、腐蚀性介质等理想的耐磨、耐蚀管道。
Ceramic composite steel pipe, all known as ceramic lined composite steel pipe, is made of high technology production technology, self burning high temperature separation synthesis. The tube is composed of corundum ceramic, transition layer and steel three layers from inside to outside. The ceramic layer is formed at high temperature above 2200 degrees, forming compact corundum porcelain (AL2O3). It forms a strong combination with the steel tube through the transition layer. Due to the high strength, toughness, impact resistance, good welding performance and high hardness, high wear resistance, corrosion resistance and heat resistance of corundum porcelain, the composite pipe has overcome the characteristics of low hardness, poor wear resistance and poor toughness of ceramic pipes. Therefore, the composite pipe has good comprehensive properties, such as good wear resistance, heat resistance, corrosion resistance, mechanical impact and heat shock, good weldability and so on. It is an ideal abrasion resistant and corrosion resistant pipeline for conveying granular material, grinding, corrosive medium and so on.
