RT-4500 weld squeeze box
Rafter Equipment Corporation has completed a RT-4500 weld squeeze box for a major North American API pipe producer.
The box is part of an upgrade to the customer's existing HFI pipe mill. It is sized for up to 4.500" OD x 0.262" wall (114.3 mm OD x 6.7 mm wall) HSLA steel pipe.
The design includes push-on-center squeeze roll adjustments, high-capacity tapered roller bearings within the roll tools, and central lubrication piping.
This project is the first of two weld box upgrades for this customer. The second weld box is for a 10" pipe mill. Rafter Equipment Corporation manufactures tube mills, pipe mills, roll forming machines, cutoff machines, auxiliary and other related tube and pipe mill machinery. Additional services include rebuilding and upgrading mill equipment. Originally started in 1917, the Rafter name is known for reliable, high-quality tube mill and roll forming equipment.
