KraussMaffei, Germany, has supplied a line
for the production of large-diameter PE-HD
pipe (OD 400mm to 1,200mm) to Emirates
Preinsulated Pipes Industries (EPPI), Abu
Dhabi, United Arab Emirates. The line
will be used mainly for the production of
PU-insulated pipe used to transport cooling
liquid for air conditioning systems in tower
blocks.
The extrusion line features a KraussMaffei
Berstorff KME 125-36 B/R single-screw
extruder with KM-RKW 36 and KM-RKW 38
pipeheads. Both pipeheads can be moved
sideways out of the line on tracks.
PES Productive and Industrial Co,
Tehran, Iran has also started operating
a KraussMaffei Berstorff line to produce
large-diameter pipe. This line is headed by
a KME 150-36 B/R extruder and a KM-RKW
39 pipehead. The line achieves an output of
1,700kg/h, producing PE-HD pipe with outer
diameters up to 1,600mm.
KraussMaffei Berstorff supplies complete
turnkey solutions to produce large-diameter
pipe, which are tailored to the specific
requirements of individual users. RKW
pipeheads are capable of producing pipe
with diameters up to 2,000mm and wall
thicknesses up to 100mm.
The company’s 36 L/D single-screw extruder
is capable of an output up to 1,700kg/h. The
36 L/D screw concept provides high output
and a gentle, high-performance plasticising
process. The longer processing unit delivers
a thermally homogenous melt with fillers
and pigment perfectly mixed in.
The company’s pipe extrusion division is
currently experiencing a strong demand
from companies manufacturing large-
diameter plastic pipes. These products are
used in applications such as water supply
and district heating networks.
