TIANJIN Zhongshun Petroleumsteel Pipe
Company is a large-scale manufacturer
specialising in the production of ERW steel
pipes and DSAW steel pipes.
With investments totalling US$37mn,
the company operates from a base of over
300,000m2 and produces 600,000 tons of
welded steel pipes annually.
Advanced equipment used in the
company’s pipe production includes three
longitudinally HF welded pipe mills, six
spirally double-side submerged arc welded
pipe mills and two anti-corrosion pipe mills.
The mills can produce longitudinally welded
steel pipes ranging in diameter from 21.3 to
457.2mm with wall thickness ranging from
1.8 to 14.27mm, and spirally double-sided
submerged arc welded pipe with diameters
ranging from 219 to 3,040mm and wall
thickness ranging from 5 to 30mm.
Many kinds of coating can also be
applied, such as FBE, 2PE, 3PE, 2PP, 3PP,
epoxy coal asphalt, internal epoxy coating,
and cement mortar lining.

Leading bar
gauge for hot
rolling mills
ZUMBACH Electronic AG has recently
extended its range of STEELMASTER rod
and bar gauges by a further and bigger model.
The new gauge, SMO 160-S6, is equipped
with 6 high-speed laser scanners ODAC® 160
and delivers up to 6000 measurements/s i.e.
1000 processed profiles/sec. It also features
Zumbach’s calibrated single scan system
(CSS) and the unique EPM method and
software (patent pending).
The gauge is able to measure rounds,
hex, squares, flats and various shapes
with outside dimensions up to approx.
140mm (dep. product vibration) in multiple
modes: static, orientable mode: measures
in 6 directions, 30 degrees spaced; partial
oscillation mode: programmable start and
stop angle, e.g. for squares or flats; full 180°
oscillation: standard mode for rounds, every
30° rotation delivers a full profile.
The EPM method and software, in
combination with CSS, makes the gauge an
effective tool at 3 roll blocks or when the bar
has polygonal or asymmetric shape deviations
– asymmetric underfill or overfills. It calculates
the typical values DT and GT for the initial
roll settings. It can also calculate and display
“Roundness” RON t according the official ISO
definition for any shape.
The mechanical system is the same as the
well proven design of the smaller gauges and
requires minimal maintenance resp. periodic
cleaning only. Smaller gauge models for wire
rod and smaller sizes are also available.
