Steel pipe diameter: Ф 108 —Ф1 016

        Steel pipe length: 8000mm-12000mm

Process speed: 1200mm/min - 5 000mm/min

3, the pipeline conveyor

According to user requirements, our single layer of epoxy powder coating Ф 108 -Ф1 016 pipe coating line is designed as a transmission line in a single round of the power unit, so that the speed of the pipeline operation more smoothly and easily adjust the size of the pitch tube. The reducer adopts WPA type, and the power is 7.5 KW inverter motor, a total of 6 sets. The power control adopts centralized control, the control cabinet is a piano cabinet, and the frequency converter is concentrated in four control cabinets. The frequency converter adopts domestic famous brands. The base of the conveyor is welded with GB 20# channel steel, 20# rectangular steel and 14mm thick steel plate. The specification of this production line conveyor is 2000mm × 6000mm × 13 (four sets of tires per rack). 2000mm × 800mm × 10, (including eight sets of tires, one assembled high-temperature wheel, and two single-frame each set of two sets of tires). The transfer wheel is a 600-9 pneumatic tire (stronger than the solid wheel, the pipe runs smoothly). The base of the transmission wheel is fixed on the adjusting rail with the same hole spacing by 4 screws to facilitate the adjustment of the size of the pipe. The angle adjustment adopts the screw adjustment, which improves the pipeline transmission accuracy and reduces the labor intensity. The total length is 90 meters.
