ALUMINIUM, ALWAYS A GOOD CHOICE
Loose aluminum flanges, for pressure till 10/16 bar, are a very interesting alternative to those made in other materials, thanks to the following characteristics, which are at the same time present in the aluminium:
Being less heavy (over30%) than steel, aluminium is more functional in installation, maintenance, loading, unloading, storage and transport.
In most cases the physical and chemical characteristics of aluminium allow the use of these flanges without any surface preservative treatement. Optionally you can cover the flanges with a coat of epoxy paint.
The practical use of millions of G.E.A. flanges for many years has shown that the aluminum flanges of our production give an absolutely reliable hermetically joint.
Thetmal conductivity – EN 47000 – at 20°C → 130-150 W/(mk)
The temperature of our aluminum flanges is considerably lower than the one of pipes: this is because the capacity oh heat conductivity of aluminum is 3 times higher than that of carbon steel alloys and over 6 times than that of steel alloys.
