While it would be advantageous to replace such aged equipment, that isn't always necessary. A minor equipment upgrade can do wonders. Improving the bar steadiers—the devices that hold the mandrel the steady as the pipe exits the mill—can greatly improve the mill's output and reduce the pipe's wall thickness variation.
Compared to conventional laser processing machines, the OPTIPLEX Fiber significantly increases the productivity of thin worksheet cutting with impressive accuracy and cuts up to 0.875” in CRS. The laser is designed to process reflective materials with greater thicknesses and at greater speeds than its CO2 counterpart.
