Segmented bends are designed for building ventilation systems based on SPIRAL ducts and plain ducts. They are made of 4 segments; bends in diameters of DN 1120 mm and greater are composed of 5 segments.
The segments are fastened by hemming and seaming. The inside surface of the hemmed seams is sealed, and as a result of the double EPDM gaskets, this solution provides air tightness class D according to EN 12237 for ventilation and recuperation systems.
The piece is connected with a duct by inserting one into the other. The pieces can be made of 1.4404 stainless steel sheet for ventilation systems in swimming pools.
