Inspection, length measurement and
weighing
Brandt Engineered Products has
provided finishing floor solutions for the
tube and pipe industry for over 30 years.
During that time it has engineered ways
to ensure its equipment produces high
quality pipe, while being robust enough
to withstand the difficult environment
that it operates in.
The company’s Weigh Measure Mark
Stencil (WMMS) provides a quick
and accurate way to help ensure that
customers are receiving material that
adheres to their strict standards. The
WMMS uses a PLC to automatically
move pipe and capture measurements.
It uses a walking beam to transfer pipe
to each station. Each unit has the option
for inspection, length measurement,
weighing, pin stamping, stencilling and
colour banding pipe.
Each of the steps is recorded in a custom
data logger, sent to the customer’s
database and available on screen for
instant observation.
Lengths and weights need to be
measured accurately and repeatedly.
Brandt has been able to employ photo
sensors and high-resolution encoders
that can ensure lengths are measured
and recorded within the guidelines of
associations such as API. The weigh
station is able to maintain defined
tolerances over repeated
use.
Shock absorbers and
load cells are designed to
ensure that the weights are
measured precisely over a
wide range of lengths and
diameters, often within ±0.5
per cent.
Labelling the pipe with a
visual record of specifi-
cations and information
observed during testing is
accomplished by stamping,
stencilling and colour banding. Being
able to produce a stamp and stencil
that can print the correct information
as well as being visible at the end
of the mill process is a difficult task.
Brandt works closely with customers
to understand the environment and
correctly choose the appropriate inks
and paints.
Stencilling is accomplished with either
a travelling stencil carriage attached
to an overhead truss, or by moving
the pipe and keeping the stencilling
equipment stationary. Stencilling
will brand each pipe with customer-
specified information such as length,
weight and any logos that may be
required. Further solutions can include
application of barcodes for quick and
accurate pipe tracking.
A turning roll is used to turn the pipe
during the application of a colour
band. Paint is supplied to automatic
spray guns via large pressure pots with
agitators to ensure the equipment is
usable on demand. Stamping is another
option that customers can choose to
add to the WMMS.

Scarfing longitudinally welded tubes
During the last 15 years, Saar-Hartmetall
und Werkzeuge GmbH has reinforced
its team, dedicated to techniques of
scarfing longitudinally welded tubes.
The company’s staff have
completely revised its range
of products, and have made
important innovations in the
design of the tooling and in the
quality of the carbide inserts
concerning geometry and
carbide grades.
The company is always
involved in specific projects
and customised equipment.
Its hydraulic inside scarfers
start from 19mm inside
diameter, and its mechanical
tooling from 14mm ID.
Saar-Hartmetall’s partnership with a
coating centre allows the company to
improve all kinds of specific scarfing
problems.
New products include short inside
scarfing tow bars, and a new hydraulic
power pack with pre-selected pressures
and return button to accelerate the
‘out of cut’ movement. The company
has also produced a new impeder
filtration and pressure station with easy
handling.
