Rafter Equipment Corporation has shipped a RT-5500 weld squeeze box for a major North American OCTG pipe producer. The box is part of an upgrade to the customer's existing HFI pipe mill. It is sized for up to 7.000" OD x 0.375" wall (177.8 mm OD x 9.5 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.

In addition to the weld box, the upgrade included a new single-sided turkshead straightener. The turkshead unit included 2-axis remote motorized adjustment with linear displacement transducers.

Finally, the upgrade included a sizing mill drive train upgrade. The existing single-motor, three-gearbox arrangement was replaced with three (3) individual motor drive units. The drive electrics were designed to integrate with the existing line electrics.
