intensive Schmelzekühlung sowie die
Rohrinnenkühlung arbeiten hauptsäch-
lich mit der Umgebungsluft und mini-
mieren so die Betriebskosten und den
Wartungsaufwand.
Die Rohrinnenkühlung verkürzt außerdem
die Kühlstrecke, was für Tehno World we-
gen des begrenzten Raumes in der Pro-
duktionshalle von entscheidender Bedeu-
tung ist. Mit der neuen Extrusionslinie von
battenfeld-cincinnati kann das Unterneh-
men Rohre mit 1,2 m Durchmesser (SDR
17) mit Durchsätzen von mehr als 1.500
kg/h sowie einer Kühlstrecke von weniger
als 40 Metern produzieren.
Die Kühlstrecke enthält zwei vacStream
1200-6 Vakuumtanks und vier cool-
Stream 1200-6 Kühltanks sowie die rest-
lichen Nachfolgekomponenten: einen
Abzug (pullStream R 1200-10 VEZ), eine
Anfahrhilfe (startStream AFH 60), eine
Trennsäge (cutStream PTA 1200) und ei-
nen Kipptisch (rollStream RG 1200).
Die gesamte Linie wird von der bewähr-
ten BMCtouch Steuerung mit einer 19”
TFT Touch Screen Benutzeroberfläche
geregelt, so dass auch die Trennsäge und
der Abzug über den Extruder-Terminal
gesteuert werden können. Die Steue-
rung bietet auch die Möglichkeit der
Fernwartung.
Tehno World is the only producer in
Romania able to produce pipes of this
diameter and has entered the European
market for large diameter pipes. The ma-
jority of the extrusion lines for smooth
and corrugated pipe at Tehno World’s fa-
cility are entirely from or include major
components from battenfeld-cincinnati.
“It has been a great opportunity for
Tehno World to collaborate again with
battenfeld-cincinnati, because we have
reached for new horizons in our field of
activity. battenfeld-cincinnati is a reliable
and valuable business partner for us with
whom we have worked in the past to de-
velop our production capacity. batten-
feld-cincinnati has demonstrated the
high quality of its service and products
while helping us to develop further and
raise our standards of technology and
flexibility,” says Iustinian Pavel, Director
of Tehno World.
The 1.2 m line produces pipe in the pres-
sure classes SDR 11, SDR 17 and SDR 26
and was introduced to Tehno World’s

customers at an Open House event in

The line is equipped with a solEX 90-40
as its main extruder and a uniEX 45-30
as co-extruder. Both operate with a high
level of efficiency, thanks to their AC
drives, optimized screw geometries and
air-cooled, bi-metallic barrels.
For the addition of color stripes, batten-
feld-cincinnati delivered a small, space-
saving coEX 30-25 co-extruder, installed
on a die trolley with a swivel arm for ea-
sy movement.
The new large-diameter line also in-
cludes some FDC (fast dimension
change) components: The pipe head is
equipped with an adjustable die aper-
ture, which consists of a conically shaped
mandrel and an outer sleeve moving in
longitudinal direction. It covers pipe dia-
meters from 900 to 1,200 mm and –
with an extension – also diameters from
500 to 800 mm (SDR 11 – SDR 26). The
FDC components are completely integra-
ted in the BMCtouch extruder control.
The helix 1200 VSI-TZ+ pipe head re-
duces sagging and pipe ovality for thick-
walled pipes, even at high line speeds,
thanks to its two-step distribution con-
cept. The active intensive melt cooling
and inner pipe cooling operate mainly
with ambient air, thus minimizing operat-
ing costs and maintenance requirements.
The internal pipe cooling also reduces
the cooling length, which is of great im-
portance for Tehno World due to limited
hall space. With the new line from
battenfeld-cincinnati, they can run 1.2 m
pipes (SDR 17) with throughputs above
1,500 kg/h and a cooling length of less
than 40 meters.
The cooling section includes two vac-
Stream 1200-6 vacuum tanks and four
coolStream 1200-6 cooling tanks and is
complemented by the rest of the line
components: haul-off (pullStream R
1200-10 VEZ), start-up aid (startStream
AFH 60), cutting unit (cutStream PTA
1200) and tip table (rollStream RG
1200).
The line is controlled by the proven
BMCtouch control with a 19” TFT touch
screen, so that saw and haul-off can be
operated via the extruder terminal. The
control also includes the option of re-
mote servicing.
Die cutStream PTA
1200 Trennsäge kann
je nach Anwendung
die Rohre sowohl
spanlos als auch mit
Spänen ablängen
