Single Wall

Materials used: Stainless Steel 304 BA (EN 1.4301 – L20), Stainless Steel 316 BA (EN 1.4404 – L50).

Thickness: 0.5 mm.

Belling: done with a mould and counter mould hydraulic expansion system ensuring calibrated joints with a tolerance of +/- 2mm.

Welding: longitudinal TIG process for the  fusion of adjoining pieces to ensure the seal of each individual component.

Accessories: triple lip silicone gasket to ensure the joint is sealed; locking band to secure the joint and ensure the continuity of the system.

Among the products offered we also make flues in Stainless Steel 304 BA 0.8 mm thick, not intended for the construction of Chimney Systems in accordance with the requirements of UNI EN 1856-1.

In such cases the forms are made with vertical edge forming machines. The female form is nominal internal diameter, the male form is tapered. Such features, not allowing for the use of gaskets and locking bands, do not ensure the seal of the system.

Its use is intended to manually regulate the draught in a flue. It can also be used to balance the flows inside a branched flue.

An elliptical valve placed inside the flue and manually adjustable from the outside using a "butterfly" mechanism performs this function. Even if completely closed, it does not obstruct the system thus ensuring it is completely safe.
