upsetters for
tubes
CEMSA has announced a new series of electrical upsetters
for use by manufacturers that have to upset tubes/pipes
mainly in drilling/perforation sectors.
This technique is made possible by a new design of the
front of the existing model RIO 100 SC SP, where a special
clamping system, new current carrier contacts and the
“in dies” more powerful forging press, hold and move the
tubes automatically. The accuracy along the full process
is guaranteed by a sophisticated, but easy-to-use, control
system.
Special care is devoted to control and monitoring the
heating progress and the forging speed in order to keep micro-
structural grains within the international strict limits fixed for
the related applications. These new models can be equipped
either with single phase or with three-phase DC dedicated
transformers, designed for continuous service. Sizes of the
tubes for “in-dies” upsetting will depend upon the relevant
thickness. Productivity will be again depending on the solution
chosen and will be confirmed on dedicated offers.

Rafter ships
seam unit
RAFTER Equipment Corporation has shipped a model RT-
7000 seam orientation unit (SOU). The machine will be used
by a major North American tube producer to hold the weld
seam directly underneath the seam annealing inductor.
The SOU is sized for pipes up to 8.625" OD x 0.375" wall.
Pipes sizes above this diameter up to 16" OD can be passed
through the unit.
Rafter manufactures tube mills and pipe mills, roll forming
machines, cut-off machines, auxiliary and other related tube
and pipe mill machinery.
