Large diameter tubing has thin walls and high strength

摘要

Cold-pilger manufacturing capacity for large-diameter tubing has been installed at the Timken Co. Gambrinus Steel Plant in Canton, Ohio. The new capability extends the company's cold-pilgered size range to 10.5 inches (266 mm) in diameter. Pilgering is a process in which both wall thickness and diameter are reduced by means of a mandrel and a pair of rolls. Tube manufacturers apply cold pilgering to modify sizes, properties, and surface finishes.
