Line for small diameter,
heavy wall thickness pipe
MYUNG Jin Machinery has delivered its
first ERWpipemill line for producing pipe
with heavy wall thickness, particularly
for high precision automotive products.
With annual production capacity up to
47,000 tons, the new plant has been
producing tubes from 27.2 to 60.3mm
diameter, and wall thickness from 5.5
to 11.2mm.
As a second project, Myung Jin has
been awarded a contract for the supply
of a high performance pipe mill line
for producing pipe of OD 101.6mm
and wall thickness of 12.7mm, from
pipe manufacturer Seah Steel, for its
requirement of API pipes.
Based on the high durability of each
stand and shaft, the double edge
forming system enables the mill line to
produce pipes with heavy wall thickness
of sch. 140. The complete line will be
supplied along with finishing equipment
such as straightening machine, end
facing and chamfering machine, and
hydrostatic tester.

Three-roll cold forming for finned
tube rolling
ESCOFIER is a specialist in cold rolling
profiles onmechanical parts dedicated to
the automobile market. The company’s
knowledge of this technology and its
associated machines are well known
by major OEMs forming threads and
splines on shafts utilised in gearboxes
and transmission systems.
As a result of its long experience,
and having successfully developed its
Flex Quatroll, a cold rolling machine
dedicated to thin wall stainless tubes
with low fins capable of working from
5 to 6m per minute, the Escofier product
line has now been expanded with the
launch of the new three-shaft Triroll
series machines, specially adapted
for rolling finned tubes utilised in heat
exchangers.
Designed to cold roll fins on steel,
copper or even aluminium tubes from
10 to 80mm in diameter, the three
numeric axes supplied on the base
version, and the various options
available, assure a simple use of the
Triroll.
For example, the machine is able to
stop and recover the finning process on
applications such as bent tubing.
The fully electric Triroll machine is
available in two sizes, and with a range
of options, offering the same modular
concept as the Flex series.
Escofier process engineering teams
have contributed to offer, along with
the Triroll machine, an optimal disk
assembly concept, assuring higher
quality and tool life. The specific design
and development allows aluminium tube
manufacturers the opportunity of saving
up to eight per cent of the material cost
by increasing the fin depth.
