Stellar acquires EIL enlistment certificate
ZHEJIANG Stellar Pipe Industry Co Ltd,
a sub-company of Stellar Tube & Pipe
Group Co Ltd, has attained approval from
Engineers India Limited (EIL).
EIL, which works under the
administrative control of the Ministry of
Petroleum and Natural Gas (MoP & NG),
Government of India, was set up in 1965 to
provide engineering and related technical
services for petroleum refineries and other
industrial projects.
Zhejiang Stellar Pipe Industry started
the EIL enlistment application in October
2010, and received the certificate from EIL
in July 2011.
With this certificate, Stellar is qualified to
directly or indirectly supply EIL associated
projects with stainless steel seamless pipes,
covering the range for OD to 273.05mm and
WT to 12.7mm.
In 2010 Zhejiang Stellar Pipe Industry Co
Ltd also gained qualification from Petrobras
of Brazil.

Sica Symposium: international
experience and innovation
AN important international symposium
took place recently at the company Sica
in Alfonsine, Italy, catching the attention
of extruder manufacturers, corrugators
manufacturers and pipe producers. There
were 43 companies coming from 14 different
nations, with a total of 63 participants.
Visitors saw first-hand new technologies for
pulling, cutting, socketing and packaging of
plastic pipes.
Noteworthy were the haul-off and
saw for HDPE pipes for diameters up to
2,000mm and wall-thickness up to 130mm.
The P 2000/14 Plus haul-off has fourteen
caterpillars; the upper eleven pivot (Sica
patented system), while the lower three are
positionable electromechanically. All the
caterpillars are anchored via connecting
rods to the machine frame, so that reaction
forces are transferred to both sides of the
frame, with clear advantages in terms of
structural efficiency and therefore better
mechanical performance. The caterpillars
have 2,200mm contact length and are made
with special high-friction low-wear rubber.
With DN 1200 to DN 2000 pipes, a maximum
pulling force of approximately 400,000 N
is generated using fourteen caterpillars.
Whereas, with DN 630 to DN 1000 pipes,
the pulling force is approximately 170,000 N
using six caterpillars.
The TRK/C/Sy 2000 is a planetary
saw with a tool that cuts without
removing material; so it is swarfless and
generates no dust. The saw is suitable
for polyethylene pipes with wall thickness
up to 130mm. The external pipe diameter
range is from a minimum of 450mm to a
maximum of 2,000mm. To best adapt to
the pipe surface, the machine is equipped
with universal clamps, with each clamp
arm having multiple rubber and pivoting
gripping elements. The frame of the
planetary saw is made of cold rolled
steel sections affording superior stiffness
and resistance to stresses. To facilitate
safe maintenance procedures, in semi-
automatic mode the movement phases are
performed using two-hands type controls.
The machine’s control system, using PLC
logic, includes a graphical touch-screen for
controlling quickly and intuitively the entire
haul-off and cutting process.
Sica’s new generation of socketing
machines are smaller and definitely
innovative; they have been revised for
higher outputs with considerable energy
savings. Among the models shown during
the symposium, there were socketing
machines for polypropylene, bi-oriented
PVC (PVC-O) and normal PVC pipes.
Unibell is the latest model suitable for
PVC pipes to be socketed with mechanical
mandrel or with integral Rieber type gasket.
The Unibell model on display had a short-
wave infrared oven and a patented cooling
system, which enable the machine to reach
outputs equal to those of standard two-
oven models but with reduced dimensions
and consumption.
Sica, founded in 1962, concluded its
symposium by reminding all guests that its
50th anniversary is approaching. Its goal is
always to be on the cutting edge, continually
investing in research and development.
