Performance comparison between roll
change robot and flexible pipe mill
NOW that automatic roll change has
become the first choice of many buyers,
the performance comparisons between
the robot and flexible pipe mill are as
follows, according to Dalian Field:
• The roll change robot keeps the
original features of an agile pipe mill
and product variety but without any
restrictions. There are a lot of restrictions
when using a flexible pipe mill because
the roll cannot be changed freely and a
variety of products cannot be produced.
• Factory space and labour costs are
increasingly high and the production line
is more and more expensive because
of the rising cost of automation. The
production of higher specification
products with the smallest and most
efficient pipe mill will soon become a
mainstream customer demand. It is very
easy for a pipe mill with a roll change
robot to create products with a wide
number of potential specifications, but
it is difficult for a flexible pipe mill to do
the same.
• Roll cost for flexible pipe mills is high-
er than that of normal pipe mills. When
compared with a roll change robot, roll
disassembly time and shut-down time
for a flexible pipe mill will be longer.
From the above analysis it is not
difficult to see that the robot not only
keeps the existing pipe mill with its
advantages of simple structure, reliable
and convenient operation and easy
maintenance, but also realises the
automatic change of specifications.
Therefore the future mainstream of pipe
mill is the roll change robot, not flexible
pipe mills.

Testing, measuring and quality control
CONTRÔLE Mesure Systèmes (CMS)
is a specialist in non-destructive testing,
and with its complete NDT range of
products in eddy current, ultrasonic
and measuring methods the company
can supply solutions for most industrial
applications.
CMS’s product line is designed to
meet inspection, testing, measuring
and quality control on both ferrous and
non-ferrous products in steel, copper,
alloys, carbon steel, stainless steel and
aluminium. All the systems (on- and off-
line) meet quality standards such as
API, ASTM and DIN.
Based on its RotoUTscan ultrasonic
rotating head the latest product from
CMS, RotoUTDim is designed for
dimensional measurements of tubes
and cables from 4 to 250mm diameter in
the production line. Measurements are
performed all around the product, with
more than 500 measurements per turn.
RotoUTDim measures in real time and
in 360° the wall thickness and coating
thickness, ID, OD, ovality, concentricity
and eccentricity. A wide range of
industrial applications are covered,
including nuclear, automotive, precision
tubes and cables, medical, and multi-
layer coating.
