摘要
为了延长挖泥船吸排泥管的使用寿命,使用了耐磨管材。介绍吸排泥管耐磨管材的选用方法和耐磨复合钢管制作工艺。着重对高铬合金和Q345低合金刚作性能比较。新管材的使用取得良好的经济效益。
In order to prolong the service life of the suction-dredging pipe of the dredger,the wear-resisting material has been used.The choice method of wear-resisting material for suction-dredging pipe and manufacturing technology of wear-sesisting compound steel pipe have been introduced.Emphatically the performance of high chromium alloy and low alloy Q 345 bave been compared.The good economic results has been got for the usage of new material.
