Tube Mills & Roll Forming
Machines
The roll forming process in a state-of-the-art
tube mill not only incorporates the best of
what stamping, extrusion and press brake
bending deliver: it also accommodates
so-called secondary operations so smoothly
as to obscure the distinction. Welding. Hole
punching. Embossing. Trimming to length.
The roll former folds them all in. It does so
while producing high-toleranced parts in
long lengths and high volumes; continuously;
without missing a beat.

OCTG & Pipeline
Manufacturing
Oil Country Tubular Goods may be the
broadest category in the tube and pipe
industry, covering as it does a span from
sensitive instrumentation tubing to petroleum
pipeline but physical size is only one factor
among many across this spectrum. A section
of pipeline in which a man can stand upright,
with his raised arms touching only air, is a
marvel. The companies reviewed here are
aware that, from this behemoth of the desert
down to the narrowest drill string, the integrity
of that piece of OCTG is wholly dependent on
the quality of its manufacture.
