Range of electrolytical processes for
pickling and electropolishing
Condoroil Stainless offers a complete
range of electrolytical processes for
the pickling and/or electropolishing of
stainless steel tubes, which is called
Elettra.
According to the need of the customer,
three different units are available:
electrolytical pickling tunnel using
induced current for application in line
with the welding profile; electrolytical
unit for the inside and outside pickling
of tubes having diameter below 250mm;
and electrolytical unit for the inside
and outside pickling of tubes having
diameter above 150mm.
The electrolytical technology, when
compared with chemical processes,
gives several advantages.
These include elimination of toxic acids
like hydrofluoric and nitric acids from
storage, working baths, gas emission
and waste water; reduction of the pick-
ling time, especially when duplex or high
nickel alloys are processed (for example
from 30 minutes to 20 seconds for AISI
304 and from 2 hours to 2 minutes
for duplex alloy); and treatment cost
reduction. The Elettra technology can
also be conveniently used for pickling
of coil sheets, plates, profiles, wire rods
and bars. A new design allows the
reduction of pickling solution volumes
for coil sheets and plates.
