New pipe chamfering machine
MF2-25
DWT is a manufacturer of portable
pipe chamfering machines and
offers specialised equipment for on-
site operations, maintenance and
production of boiler panels for water
wall boilers. Deutsche Babcock, a
German boiler manufacturer, developed
the portable pipe chamfering machines
for the need and with the experience of
their own people on-site. Consequently
the machines are constructed in
a very sophisticated manner. The
most important advantages are: very
low weight and ergonomic; special
applications for boiler tubes; high
effectivity and power; and long lifetime.
Using the new machine MF2-25 boiler
tube chamfering of tube and fin in a
simultaneous operation at a steam boiler
panel wall is possible. The machine
can be operated with pneumatic or
electric motor and uses crown milling
pipe cutters for this special operation.
Especially for supercritical boilers with
smaller pipes but high wall-thickness
the machine is outperforming, because
the pipe chamfering machine clamps
the pipe from outside and gives the best
fixation for this operation. Pipe edges up
to 15mm wall thickness can be bevelled.
In practice it has been proven
that weld preparation of pipe edges
significantly influences the quality of
the welding junction. Automatic orbital
welding technology is getting more and
more common, which requires a perfect
and effective weld preparation by use of
mechanised pipe weld preparation.
