Brandt launches thread tables
BRANDT Engineered Products has
designed and delivered pipe handling
equipment known as thread tables
to many tube and pipe producers. Its
thread tables integrate with the most
modern machine tools. These tools are
big bore lathes, often called ‘threaders’
and are being used to produce both API
and premium threads on tube and pipe in
today’s market place. Brandt equipment
offers a competitive edge by positioning
material in and out of the threaders
quickly, keeping up with the improved
cycle times offered by the latest machine
tool suppliers. Maintaining cycle times
with threaders is a critical variable to
ensure the investment in the machine
tool is achieving maximum return.
The Brandt thread table utilises
adjustable stops to position one pipe
at a time on the table. The table is
designed with four independent idler
rolls used to absorb vibration while the
pipe is spinning during the threading
process. The independent idler rolls
were engineered and manufactured
to reduce unwanted pipe movement
at multiple locations along its length.
In the new thread table design Brandt
has added containment rolls. This
dampens the whipping motion of pipe,
allowing the machine tool to produce
API and premium threads on the end
of each pipe with greater confidence.
The new design features independently
controlled turning rolls and containment
rolls. This allows the operator to adjust
the setup for an individual pipe.
Pinch rolls are used at the head of
the thread table to protect the machine
tool and improve position control
while elevating V-rolls enable various
diameter pipes to be fed into the
machine tool at the proper elevation.
In the new design Brandt has improved
the pinch roll assembly by adding twin
lead ball screws. This has resulted in
more consistent pinching of the pipe
and improved position control. The
new design is meant to eliminate costly
repairs caused when pipes bump
the machine tool upon entry. These
improvements also mean a reduction
in overall cycle time to produce a
thread. Saw tooth style paddle arms are
used to transfer the pipe in and out of
the machine simultaneously with quick
cycle times, enabling maximum uptime
and productivity.
The Brandt thread table provides
benefits by maximising valuable
machine tool time, maintaining low
cost of production and maintenance,
minimising rework caused by unwanted
pipe movement and increasing
productivity through quick material
handling.

Roll-less forming for small
stainless steel tubes
AS well as traditional roll forming
tube mills, W&J, Taiwan, has recently
developed roll-less tube forming
technology. W&J Roll-less Mill WNJ-
SMBT is a stainless steel pipe making
machine, using non-roller forming
technology. This innovative design is
used to produce stainless steel tubes
for bellows and soft pipes with very thin
wall thickness and big diameter. The
main structure of line consists of forming
system, welding system, traction system,
sizing system, cutting system and
electrical control system. It is suitable for
tubes of stainless steel 300/400 series,
Inconel 625, 718 and Hastelloy C-276
with wall thickness from 0.12 to 0.5mm.

Slitting and packing lines for
coils from Italy
GUIDA Impianti SpA was established
in 1962 to build slitting and packing
lines for coils. More than 800 lines and
machines have been built to date.
The company’s lines are projected and
built for a long production life (many are
still working after 45 years’ production),
with easy and inexpensive maintenance,
low expense for spare parts, low noise
and low operator effort, and in respect
of safety law requirements to meet
2006/42/EC standards. Guida uses
special materials chosen after many
tests, taking advantage of experience
in the field, checking and testing new
instruments and technologies.
Easy maintenance is achieved by
designing the mechanical units to allow
for disassembly. Low expense for spare
parts is possible thanks to the use of
first quality components that grant long
production life.
The ‘scrap chopper’ is an important
and strategic machine in the slitting line,
used to cut the scraps instead of recoiling
them by use of a traditional scrap
recoiler. Guida uses a specific material
for the scrap chopper blades – a special
alloy studied by Guida technicians in
cooperation with an external partner
with metallurgy experience.
