Stainless steel specialist
Jürgen Witte Nederland BV is well known in the market for stainless steel
pipes and fittings. Being one of the largest German stockists for special
grades, and due to close, long-standing contacts with well-known European
manufacturers, the company can fulfil requirements and quickly realise special
solutions.
The company’s stock includes pipes, elbows 90°, 180°, SR, LR, 2.5xD, tees,
reducers, stub ends, collars, flanges to ASME and DIN, and high pressure
fittings 3,000 and 6,000 lb to ASME.
Dimensions for seamless products include OD up to 8", partly up to 10", thin
wall and heavy wall, sch 10s up to 80s, partly up to XXS. For welded products
dimensions are OD up to 20", thin wall, sch10s and 40s.
Seamless grades include 321/1.4541, 321H, 316Ti/1.4571, 904L/1.4539, duplex
UNS S31803/1.4462 and 304H/1.4948. For welded products 904L/1.4539 and
Duplex UNS S31803/1.4462 are available.
The company mainly stocks products from manufacturers that are PED and
AD-2000 approved. Most DIN positions are certified to AD-W2 resp VdTÜV.
Jürgen Witte can also quote for other high quality grades, such as nickel
alloys.

From June 2008, Pancar Yem in Konya/
Turkey will be producing irrigation pipe
on a QuickSwitch extrusion line from
KraussMaffei. Pancar Yem is a subsidiary
of the agricultural conglomerate Konya
Şeker, one of Turkey’s largest sugar
producers. The pipe produced by
Pancar Yem will be deployed in Konya
Şeker’s company-owned sprinkler and
drip irrigation systems.
Because the irrigation systems need to
be adapted to local situations, the pipes
are produced in different dimensions
and in relatively small batches.
This makes KraussMaffei Berstorff’s
QuickSwitch extrusion line an effective
and cost saving solution. It allows
Pancar Yem to meet requirements with
very short lead times and low stock
levels.
On a QuickSwitch line, pipe dimensions
can be changed automatically at the
touch of a button within a matter
of minutes, without interrupting
production.
The QuickSwitch line that KraussMaffei
Berstorff is commissioning for Pancar
Yem will produce single-layer pipe made
of PE-HD with a diameter between 70
and 160mm.
The line is headed by a KraussMaffei
Berstorff KME 75-36 B/R extruder with
throughput up to 700kg/h. In addition
to the QuickSwitch core components
(pipehead, suction bell and calibration
basket), the system also has a vacuum
tank, spray baths, haul-off and cutting
equipment modified for QuickSwitch
dimension change. The QuickSwitch
line allows Pancar Yem to change
dimensions within minutes.
This compares favourably with a
conventional pipe extrusion line, where
changing pipe dimensions involves the
time and cost of changing components,
stopping the line, lost production, the
start-upprocess and thewaste produced
as the line is restarted. QuickSwitch
reduces these costs to a minimum.
Drip irrigation systems are increasingly
popular because they make effective
use of water. As the name implies, water
is dripped directly to the roots of each
plant at a rate that exactly matches
the needs of the plant. This highly
Efficient production of irrigation pipe
efficient use of water reduces water
consumption and labour costs, power
consumption and fertiliser use. At the
same time, it increases fruit quality and
quantity.
KraussMaffei is a manufacturer of
machines and systems for plastics and
rubber processing, with three divisions
– injection moulding technology,
extrusion technology and reaction
process machinery. The group offers
a wide range of solutions that include
specialised and fully integrated turnkey
systems.

New 130 amp bevel
consumables
Hypertherm has announced the addition
of new 130 amp bevel consumables
to its HyPerformance ® (HPR™) Plasma
family of products, which will allow lower
power bevel cutting with the HPR130
and the HPR260.
The addition of the new consumables
will extend the existing bevel capabilities
currently available by enabling high
quality, full bevel cutting capabilities up
to 45° on thin plate.
The consumables, which will enable
the cutting of both mild and stainless
steel, are part of the company’s ongoing
commitment to improve cut quality,
consistency, and overall performance
while lowering the operating cost of its
systems.
Dave LaPrade, business team leader
of Hypertherm mechanised systems
commented, “We believe the extension
of these new 130 amp consumables to
our already existing bevel product line
will be very well received in a market that
is looking for this capability.”
Hypertherm designs and manufactures
advanced metal cutting systems for
use in a variety of industries such
as shipbuilding, manufacturing and
automotive repair. Its product line
