Filtration systems for
welded tube production
AGR Filtri produces filtration systems
for emulsion used in metal processing
machinery such as HF welded tube
production lines and profile mills for both
the Italian market and abroad.
Filtration systems study, design
and manufacturing are carried out
within the 2,000m2 wide manufacturing
facility. The experience obtained after
35 years in the business allows the
company to offer not only a range
of standard products but also as
a series of special, individual and
centralised systems, built according
to the customer’s specific technical
requirements.
To meet the market needs in the
field of filtration, AGR Filtri provides
quality systems with lasting reliability
and completely safe thus reducing
maintenance costs to almost nil.
The continuous search to improve
its products, technical assistance and
spare parts service is an essential part
of the company’s activity all aimed
towards customer service and customer
satisfaction.
Emulsion used by HF welded tube and
profile mills for cooling and lubricating
needs gets dirty quickly because of
the high quantity of metal contaminant
particles released during the production
cycle.
The continuous sludge releasing
and accumulation into the emulsion
involves the following negative effects:
fast emulsion lubrication and cooling
properties loss; rust formation on tubes
and profiles; fast wear on forming and
sizing rolls; emulsion temperature
increasing with consequent production
of waste products; fast emulsion
putrefaction with nasty odour emission
and bacteria formation; frequent
interventions for coolant replacement;
frequent interventions for cleaning
operations on basements, channels,
underground, collection and settling
tanks; high maintenance and operating
costs; nozzles blockages; sludge
deposit into heat exchangers, cooling
towers and chillers; and bad welding
tube and bad profiles quality caused
by the possible lines formation on their
surface.
In order to solve all these problems
it is necessary to adopt
a filtration system able to
remove continuously and
automatically the sludge
contained into the emulsion
allowing a considerable
yearly money saving on
maintenance costs.
