Description

一种增强环氧树脂不锈钢复合管
技术领域
本发明属于机械技术领域，涉及管材，尤其是涉及一种增强环氧树脂不锈钢复合管。
背景技术
不锈钢被广泛应用于石油、天然气、水、煤气、蒸汽等的运输管道材料，普通不锈钢经过长时间使用后，在空气中氧气和水的作用下会被逐渐腐蚀，而且随着时间的推移，这种腐蚀会持续发展下去，最终导致不锈钢表面易碎易开裂，当不锈钢表面出现裂纹后，会迅速向整个体积蔓延，最终使不锈钢断裂。实践中，可以利用油漆或耐氧化的金属，例如，锌、镍和铬进行电镀来保护不锈钢表面。但是，这种保护仅是一种薄膜。如果保护层被破坏，下面的钢便开始锈蚀。而管道内部在长时间流体的冲刷后，会逐渐丧失其光滑表面，而从管壁上脱落的物质会对流体产生污染。
发明内容
为解决上述技术问题，本发明提供一种增强环氧树脂不锈钢复合管。
本发明的技术方案是：一种增强环氧树脂不锈钢复合管，包括中空的无缝不锈钢管，所述的无缝不锈钢管外壁附着有玻璃纤维增强环氧树脂层，内壁附着有颗粒增强环氧树脂层，所述的内外层环氧树脂的厚度均不大于2.0mm。
当从外部对不锈钢复合管施加径向压力时，玻璃纤维可以有效减弱力的作用效果，当表面出现有裂纹时，当裂纹扩展到玻璃纤维处时会被挡住，减弱裂纹的扩展功，防止裂纹继续扩散。
颗粒增强环氧树脂层具有良好的耐腐蚀性和耐磨性，可以很好的解决流体所造成的腐蚀和磨损问题。
进一步，所述的内外增强环氧树脂通过注塑或喷塑方式固定在管体的内外壁上。
进一步，所述颗粒增强环氧树脂层使用碳化硅作为增强粒子。
本发明不锈钢复合管的优点在于：1、设计合理，结构简单，易于加工制造。2、由于环氧树脂具有较高的防腐蚀性能，因此能够有效避免因不锈钢内壁与流体接触而造成损坏。3、玻璃纤维增强环氧树脂层的使用可以有效保护不锈钢外壁，防止裂纹的产生及扩展。
附图说明

具体实施方式
下面结合附图和实施例对本发明进一步说明。
如图l所示，一种增强环氧树脂不锈钢复合管，包括中空的无缝不锈钢管1，所述的无缝不锈钢管外壁附着有玻璃纤维增强环氧树脂层2，内壁附着有颗粒增强环氧树脂层3，所述的内外层环氧树脂的厚度均不大于2.0mm。
当从外部对不锈钢复合管施加径向压力时，玻璃纤维可以有效减弱力的作用效果，当表面出现有裂纹时，当裂纹扩展到玻璃纤维处时会被挡住，减弱裂纹的扩展功，防止裂纹继续扩散。
颗粒增强环氧树脂层3具有良好的耐腐蚀性和耐磨性，可以很好的解决流体所造成的腐蚀和磨损问题。
所述的内外增强环氧树脂通过注塑或喷塑方式固定在管体的内外壁上，所述颗粒增强环氧树脂层3使用碳化硅等超硬耐磨材料作为增强粒子。
本发明不锈钢复合管的优点在于：1、设计合理，结构简单，易于加工制造。2、由于环氧树脂具有较高的防腐蚀性能，因此能够有效避免因不锈钢内壁与流体接触而造成损坏。3、玻璃纤维增强环氧树脂层的使用可以有效保护不锈钢外壁，防止裂纹的产生及扩展。
