Strongsville, Ohio, USA, January 23, 2015 – Rafter Equipment Corporation has completed a RT-7000 weld squeeze box for a major North American tube producer. The box is part of an upgrade to the customer's existing HFI tube/pipe mill. It is sized for up to 8.625" OD x 0.500" wall (219 mm OD x 12.7 mm wall) HSLA steel pipe. The design includes motorized push-on-center squeeze roll adjustments, linear displacement transducers, high-capacity tapered roller bearings within the roll tools, and a removable head roll assembly for quick-change. A second removable head was included to speed the changeover process even more.
Integrated with the weld box was a weld bead upset nicking wheel system and a tandem OD bead trimmer. The nicking wheel unit is designed to provide truly hands-free weld bead upset removal. Also included was an RT-4500 ironing stand for use with the customer's ID scarfing system.
