The invention discloses an anti-wear bush of a pipeline. The anti-wear bush comprises an anti-wear bush body attached to a process pipeline. An anti-overturn part overlapped to the adjacent process pipeline to prevent the anti-wear bush body from being overturned by an air flow is arranged on the outer side face of the anti-wear bush body. In a using process of the anti-wear bush of the pipeline,the anti-wear bush body is fixed to the periphery of the process pipeline, and the anti-overturn part is overlapped to the adjacent process pipeline. When the air flow blows to the anti-wear bush of the pipeline, the anti-wear bush body is subjected to torque action toward to one side and the anti-overturn part is overlapped to the adjacent process pipeline to apply a torque opposite to the direction of the air flow to the anti-wear bush body, so that the anti-wear bush of the pipeline is prevented from being deviated or overturned.
