The new machine, the second threading
machine supplied by SMS group to JFE,
will be designed to thread pipes in the
diameter range from 139.7 to 406.4 mm
with wall thicknesses from 7.0 to 50.8 mm
and lengths of up to 15 m. The type TCG
43/4 machine operates according to the
“stationary tool – rotating pipe” principle.
With this method it can cut standardized
inside and outside threads as well as all
premium threads. Thanks to latest FMEA
(failure mode and effects analysis) technology
and temperature control, the machine
has excellent stability and produces threads
of highest quality. The pipe threads comply
with the production standards for all API
5CT steel grades, JFE grades and other
international standards.

HMI system. The caster will produce the
starting material for hot charging into bar
rolling mill.
The rolling line will consist of a furnace
discharging area, a 6-stand roughing mill,
a 6-stand intermediate train and a 4-stand
finishing train. All rolling stands will be of
the Red Ring Series 5 design. The rolling
mill will also include an inline PQS quenching
system and a 54-m-long cooling bed,
