Flange is an item that connects two components of a piping system, which enables its dismantling by non destructive operations, thanks to a circle with holes where the union bolts are matched. The Pressed Flange ﬁttexport is the improvement not only in design and functionality but also in price of the traditional Back-Up Flange (we will also call it “solid ﬂange” or “plate ﬂange”). It’s the same product and oﬀers the same technical performance in less weight and less price.
A pressed ﬂange is 61% lighter than a solid ﬂange, which means also a noticeable reduction of the price. The pressed ﬂange is cheaper than the solid ﬂange. Thanks to its lightness, the pressed ﬂange is easier to install than the solid ﬂange.
The morphology of the pressed ﬂange increases the water-tightness inside the system, because it has a ﬂap in the interior diameter in contact with the collar, which exerts a pressure on the collar higher than the one exerted by a solid ﬂange.
In summary, the pressed ﬂange has the same behaviour as a solid ﬂange, with more features.
