Shot blast machine for pipes
CUSTOMERS that buy from OMSG –
Officine Meccaniche San Giorgio SpA,
based in Milan, are looking for a shot
blast machine that can offer innovative
technology, superior quality of materials
used for the construction and reliability
over a long service life.
The shot blast machine with roller
conveyor type LAUCO 100 H120 aims
to cater for all of those requirements.
The companies products are distributed
to the world’s leading companies in the
petrochemical and oil and gas field in
Brazil, Norway, India, USA, Middle East
and Australia.
The OMSG machine is suitable for
treating pipes with diameters from
200mm to 1,200mm and lengths from
6,000mm to 12,000mm. A distinctive
feature of this shot blast machine is
that, in addition to the external blasting
carried out by means of centrifugal
wheels designed and patented by
OMSG, it is able to treat, at the same
time, the inner surface of the tube using
a nozzle of compressed air combined
with blasting pot of 300 litres capacity.
The obvious advantage is the
considerable reduction of working
times.
The work-pieces are loaded on
a special roller conveyor from an
automatic transfer system. Then they
are introduced by the roller conveyor
into the blast room where, under the
influence of the stainless steel shot
thrown by the wheels, the pipe is blasted
with a degree of SA 2 ½, according to
the reference standard ISO 8501-1.
At the same time, a nozzle of
compressed air previously selected
according to the diameter of the pipe to
be treated is automatically positioned
at the inside of the pipe and begins the
cycle of internal blasting.
At the end of the blasting operation
the pipe is emptied of shot remains by
an automatic lifting system that allows
the pipe to tilt and overturn the shot
into the recovery hopper. By means
of a transfer system, the pipe is finally
discharged from the roller conveyor.
