The invention discloses polishing equipment for a glass reinforced plastic pipe. The polishing equipment comprises a base, longitudinal moving mechanisms, oil cylinders, a cross beam, a polishing rack, a motor, a belt, a driven pulley, a polishing wheel, the glass reinforced plastic pipe, connecting shafts, supporting wheels and a supporting frame. The polishing equipment solves the problems that the outer circles of the glass reinforced plastic pipe are polished manually by workers in the prior art, the labor intensity is high, the time and the labor are wasted, the stability is low, polishing machines used in the operation process are dangerous and injury accidents occur easily. In the use process of the polishing equipment, the glass reinforced plastic pipe is placed on the supporting wheel in the supporting frame, then the polishing equipment is started to enable the motor to rotate, the motor rotates and drives the polishing wheel to rotate through the belt, then the oil cylinders descend so that the polishing wheel can polish the outer circles of the glass reinforced plastic pipe, and the longitudinal moving mechanisms move in the front-back direction for polishing the outer circles, located at different positions, of the glass reinforced plastic pipe.
