Cellular beam bender
BARNSHAW Section Benders has been
involved in several large-scale energy
and renewables projects. A recent
job involved the company’s structural
division working with ASD Westok and
Fisher Engineering, which is a part of
Severfield-Rowen plc.
Working together with ASD Westok,
Barnshaws was asked to produce some
of the deepest cellular beams ever
requested, the largest being a 1,594mm
deep beam formed from one of the
biggest universal beam sections that
Tata produces. The beams were not only
large in terms of depth, but also in length,
with upwards of 23m of bar to be curved.
Barnshaws has also been curving
a number of bars direct for Fisher
Engineering, which includes a variety of
sections and sizes ranging from 457mm
deep universal beams to 400mm deep
rectangular hollow section (RHS).
Both cellular beams and sections have
taken the company’s expert benders 3
to 4 months to form, and together they
weighed approximately 500 tonnes.
Barnshaws has a strong relationship
with ASD Westok, and the early
consultations enabled the client to see
that Barnshaws was willing to invest
heavily in order to meet its requirements.
Barnshaws has invested more than
£70,000 on new equipment and tooling,
which means that the company can
now curve the largest cellular beams
available. Barnshaw Section Benders is
based at six manufacturing sites around
the UK, located in the West Midlands,
Manchester, and Hamilton in Scotland.

Pipe cutting and
end preparation
MACTECH Europe is a supplier of pipe
cutting and end preparation equipment,
including lightweight and rigidly con-
structed machines that can be used in
almost any environment, even subsea.
The company is also able to provide a
wide range of on-site machining services
both in the UK and internationally.
All on-site retained service
assignments are accompanied by
qualified technicians who are well
versed in applications such as weld
excavating, to remove defective weld
material, match boring to enable pipes
with dissimilar wall thicknesses to
be welded together, generating weld
preparations in the standard 30 deg and
37 deg profiles along with compound or
‘J’ bevels and any other problems they
may encounter.
The pipe cutting and end preparation
machines are manufactured to be
durable, and are maintained to the
highest standards, ensuring that they
will perform to demanding tolerances
under virtually all conditions.
Mactech Europe has proven expertise
across many major industry sectors,
including petrochemical, power genera-
tion, LNG, shipbuilding, offshore oil
and gas, subsea, engineering and
fabrication, and papermaking.
The Mactech Europe Air Operated
Trip assembly has been introduced to
offer safe remote operation of the feed
trip pin combined with a two-handed
start control. This ensures the operator
has full control of the operation of the
clamshell lathe while remaining outside
the potentially hazardous zone.
The start handle and the trip assembly
use air taken from the main air supply
to the clamshells pneumatic drive motor
and no other power source is required.
To start the machine the operator must
use both hands; after start up, only one
hand is needed to keep the machine
running, leaving the other hand free to
operate the control of the feed pin. If
the operator releases the run control,
the machine will come to a stop and
the feed pin retracts automatically. The
air operated trip assembly is a direct
replacement for the manual version with
no other modifications necessary.
