Many seamless tube producers in North America use cross-roll piercing mills built in the 1950s that were based on designs from the1930s. 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.
