Carry out open-case inspection of equipment, propose handling suggestions to damaged or missing parts

Mark out or pop up cross curve as per the layout chart

Hoist and put the roller bed drive system in place as per the cross curve position

Align and level the roller bed drive system, ensure center line and elevation of longitudinal roller consistent

Hoist and put the cutting trolley system in place as per the cross curve position

Align and level the cutting trolley system, ensure cutting trolley system and roller bed drive system parallel

Hoist cutting power system and other dismantled parts

Install electric wires and connect with gases

Carry out a preliminary maintenance to the equipment

The equipment and distribution box must be connected by licensed technician

Single Machine Commissioning

Switch off the power switch on the electrical cabinet, press the start button on the panel and switch on the power.

Test whether cutting torch base lifter, double yawing joint of cutting torch and ovality detector work normally.

Drive cutting trolley system, test whether it can run in the guide normally and front and back limit switch works.

Turn to the forward switch and reversing switch of roller bed drive system and test whether the rotation direction of the pipe is correct.

Conveying the pipe into the roller bed drive system by the lateral conveying system, test whether the limit works normally. Adjust the limit switch and corresponding components as need.

Test whether axial displacement and rotation precision of the pipe reach the requirements on the roller bed drive system.  

Switch on the cutting power for plasma and flame cutting, check whether cutting effect reaches the normal level.

Improve the manufacturing quality and installation quality, and modify the parameter based on the commissioning results of the machine.

Ganged Machine Commissioning

Follow the following procedure, put a pipe not less than 6 m in length and DN600(24 ")/ DN120(48 ") in diameter on the roller of lateral conveyor, and then proceed length measuring, pipe end and pipe mouth profile cutting.

Improve the manufacturing quality and installation quality, and modify the parameter based on the commissioning results of combined operation.
