material table simplifies material handling
directly at the cutting point. The machine
comes with a micro spraying system as
standard.
The machine can be supplemented as
required with infeed and discharge roller
conveyors, measuring devices and cross
conveying systems, as well as NC angular
adjustment. Behringer GmbH supplies
these highly process-reliable customized
transport solutions from its own in-house
steel production facilities.

First spiral pipe
produced on a
Schuler plant
Plant at Tuberías Procarsa in
Mexico ready for operation
Experts predict that in North America alone,
over 10,000 kilometers of new pipeline will
be laid per year by 2020. And most of that
will be spiral pipes. Tuberías Procarsa, one
of the leading manufacturers of steel pipe
in Latin America, is equipped for this trend:
the company with headquarters in Monclova
(Mexico) has put a spiral pipe plant from
Schuler into operation and used it to produce
large-diameter pipes.
The offline spiral pipe plant can produce large-
diameter pipes with a diameter of 508 to 2,235
millimeters (20 to 88 inches) and a length of 12 to
24.4 meters. The raw material up to 25.4 millimeter-
thick sheet metal band made of high-quality steel (up
to X100) comes on a hot rolled coil (HRC). The spiral
mill forms the diameter and welds the spiral pipe
within the first step by tack welding. In a further
process, the final pipes will be weld by several final
welding stands with a submerged arc welding process.
An innovation from Schuler is the integrated coil
preparation stand. It ensures short changeover times,
high occupational safety and an exact 90-degree
cut of the beginning of the band. A crane transfer
is no longer necessary. All relevant work steps on
the spiral mill are automated: settings are no longer
made manually; instead, setting is done directly on
the well-organized control panel and implemented
by servo motors. This results in an energy savings
of up to 30 percent and short changeover times. At
a length of 285 meters, the pipe plant also includes
various equipment for inspecting the large-diameter
pipes in accordance with the API 5L standard.
Ultrasonics, X-rays and water pressure stands are
used here. The production capacity of Tuberías
Procarsa will be increased by 200,000 tons a year
thanks to the Schuler system.
