The aluminium flanges are located inside the pipe and lean against a welding collar, which is welded to the pipe, and represents the only part of the joint in contact with the fluid. In this way, it is possible to use this flanges’ typologies with strong fluids too.
The use of the aluminium flanges in the plants is characterised by many advantages, such as a good resistance to the corrosion and the lightness: this allows the installation and the maintenance in an easier way, guaranteeing the strength and the resistance of the stainless steel flanges, anyway.
In our company are available steel flanges with suitable dimensions to the pipes both with dimensions that respect standards UNI 6089 and with metric dimensions.
