Latest Patents

Lefebvre holds a patent for a method of making a seamless hot-finished steel pipe. The patent describes a process where a billet heated to a shaping temperature is pierced to create a thick-walled hollow ingot. This ingot then undergoes a radial forging process using an internal tool and at least two forging jaws of a forging machine. The forging jaws act on the outer surface area of the hollow ingot, which is turned and axially advanced in a clocked manner during the idle stroke phase of the forging jaws. This innovative method enhances the efficiency and quality of steel pipe production.
