Orbiter™ MCL

A standard spray nozzle is attached to the robot arm, with the centre line immediately above the girth weld. To guarantee uniformity of coating thickness the speed of movement is precisely controlled.

The robot orbits the pipe several times according to a defined sequence, which prevents excess deposition of coating, even when the movement reverses direction.

Tested on pipe sizes from 12 Inch and upwards, the operator benefits from the Graco® plural metering machine being integrated with the spray robot control. This improves quality over a large operating range regardless of which manufacturer’s coating system is in use, reducing the use of materials and the number of operators required.
