The Manual Hydraulic Series of butt-welding
machines in the new LI-Line generation makes
a statement by its superior manufacturing
quality and its scalability in the form of an easy
upgrade to a data logging-enabled machine
with the installation of an SPG 2.0 data logger
for welding report generation.
■ The machine ships with a hydraulic unit
that features, as a unique first, a totally
integrated enclosure that also is a splash
and dirt shield for all components on the
inside. The front panel controls, too, are
included in the ingress protection according
to the IP 54 rating (where IP 64 is possible
upon request).
■ All connections, including an additional
power socket free to use for the operator’s convenience, are located at the back
of the controller. Both the facing tool and
the heating element are also connected at
the back panel of the hydraulic controller.
Therefore, no additional power distribution
unit is needed.
■ The hydraulic unit also doubles as the
central control panel of the machine with
which the user performs all relevant settings
and process steps. The front panel features
a GT keypad, the critical process controls,
and also the digital temperature control for
the heating element and the extra-large and
conveniently readable pressure gauge.
■ All HÜRNER Manual Hydraulic butt-welding
machines can easily be upgraded with the
HÜRNER data logger SPG 2.0 for welding
parameter viewing, monitoring, and recording. As a consequence the model version
“Manual + SPG” of the butt-welding
machine complies with mains gas distributors’ specification requirements, which state
that data recording and report generation
is mandatory, but do not require automatic
welding processes.
■ The 4th clamp of the machine chassis can
be easily removed by loosening 3 bolts,
for welding operations at locations where
positioning the machine is a challenge and
for joints with tees or other fitting elements.
This turns the machine into a fully functional
“short” chassis with only three clamps.
■ The machine chassis is set on a specifically
developed support frame exhibiting a warp
resistance that manages with ease even the
most extreme pipe parameters. Operators
can be sure that the machine chassis does
not tilt or twist even when very long lengths
of pipe with very thick walls are processed.
■ Large, knurled turning knobs mean easy
handling for the operator who opens or
closes the clamps of the machines sized up
to O.D. 315. No tools are needed for this.
■ The facing tool with integrated micro-safety
switch is driven by a high-quality power
drive engaged by a transmission chain. The
precision heating element ships with a very
rugged anti-stick coating.
■ A carrying rack is provided for the heating
element and the facing tool, to store them
with no worries about the heat.
■ Maximum protection of the machine,
while it is stowed away, is provided (up
to O.D. 315) by an optionally available,
high-quality transport box that has been
specifically designed for the entire machine
assembly, with drawer-style storage compartments for the reducer inserts.
■ For all machines a welding neck support is
of course available, too.
