The line of AVIT flange products, which features standard connection dimensions in accordance with ISO 6164, has been continuously expanded and improved throughout the decades. Changes in the design ensure a flange connection that is more reliable, compact, robust and maintenance-free than conventional SAE-, ANSI- or DIN -/ EN-flange connections.

Due to different flange head lengths the dividing joint was shifted to achieve an asymmetrical division. The flange head is centred in the counter loose flange. This relieves the bolts of transverse forces which are responsible for the possible loosening of a connection. The leakage path is diverted in case of a gasket failure, in order to prevent potential source of danger. Assembly is easier and more precise due to the centring and the loose flange system. This eliminates misalignment in the pipe and any related turbulences or flow losses.
