Strongsville, Ohio, USA, April
21, 2009 – Rafter Equipment Corporation today shipped an RT-9000 five-roll weld squeeze box. The weld box will be installed as part of
an ERW pipe mill upgrade at a prominent North American facility for the
production of up to 16” (400 mm) OD API line pipe.
The weld box features powered
adjustments with actuators that push on the centerline of the weld squeeze roll
tools. This feature eliminates any cantilevered loads and the long-term
maintenance consequences of such cantilevered designs. The unit also includes
position feedback using linear transducers and a graphical operator interface
for more repeatable setups.
Additional quick-change features were added to minimize the amount of
time and effort necessary to change the roll tooling. The new open design
allows for operator access to the downstream side of the unit for easier
inspection, setup, and replacement of the ID weld bead cutting tools. An
integral tandem OD weld bead trimmer and bead winder with powered bundle
push-off were also included.
Rafter Equipment Corporation manufactures welded-seam
tube and 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.
