Wheel conveyor for blasting and side extrusion coating lines
The wheel conveyor is used in the blasting and side extrusion coating lines. The pipe moves forward while rotating (helix movement). The wheel angle adjustment is activated by means of spindle jacks, powered by an electric motor. The helix adjustment is fitted to accomplish an adjustable rotation versus linear movement of the pipe.
Variable pipe production speed
A frequency control system in sections is provided to obtain a variable pipe production speed and to catch up and break away the pipes at the incoming and outgoing parts of the conveyor, by increasing the conveyor speed of the relevant section. In order to accommodate various pipe diameters, the conveyors are generally foreseen of side to side distance adjustment of the wheels supporting the pipe.
