Pipe extrusion lines: A success story
for China - made in China

Expansion of the market position thanks to the
successful Performance Series
“Economical production, high outputs and perfect
end product quality have also long been standard
requirements in the mechanical engineering and
system construction industry in China,” emphasized
Michael Hofhus, Vice President Extrusion at
KraussMaffei Berstorff in China. “As a competent
system supplier, we have been satisfying precisely
these needs of our customers through our product
portfolio in the Performance Series from our plant
in Haiyan for several years. On a highly competitive
local market processors focus on both quality
and lower unit wage costs,” said Hofhus. The twinstrand line, which will produce PP-R pipes live from
12.00 to 13.30, will demonstrate very clearly how
economical production functions in a confined
space.
“In the last few years we have placed complete
lines up to a diameter of 1200 mm on the market.
However, we are not only very successful as a
system supplier for complete lines, but also in
business with individual machines,” added Hofhus.
“With our single-screw extruder model KME 6030 B/R from the Performance Series, we offer
processors a suitable machine concept, especially
in regard to locally used materials,” said Hofhus.
The 30D Series, an extension of the single-screw
series that has been used successfully for many
years, is perfectly designed to process local PP-R
material thanks to its revised screw concept. “The
advantage here is the short processing unit which
ensures optimum thermal and material melt
homogeneity with high output, and therefore
a final product of the highest possible quality.
Another important criterion for Chinese producers
who are increasingly setting themselves apart from
competitors on the local market through highquality products,” said Hofhus. The exhibit in the
30D Series, which is produced at the production
plant in Haiyan, is equipped with the new userfriendly C6 control system with its modern
operating philosophy.
The line will produce PP-R pipes with a diameter
between 20 and 40 mm at a speed of up to 25 m/
min per strand and an axial distance of 450 mm.
The core components of the line are the singlescrew extruder KME 75-30 B/R, two co-extruders
KME 20-25 D/C for strip production and two pipe
heads KM-RKW 32 from the locally produced
Performance Series. The line is completed by other
components ranging from a suction conveyor, a
cooling zone, a saw and a haul-off through to a
