The Stainless Steel "FF" Length is a double female form component in accordance with the requirements of UNI EN 1856-1.
Among the products offered, we also make flues in Stainless Steel 304 BA 0.8mm thick, not intended for the construction of a Chimney Flue System 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 internal nominal diameter and 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.

Thickness: 0.5 and 0.6 mm in 304 AISI (EN 1.4301), only 0.5 mm in 316 AISI (EN 1.4404).
Welding: longitudinal TIG process for the fusion of adjoining pieces, without filler.
Belling: done with a mould and counter mould hydraulic expansion system guaranteeing calibrated joints with a tolerance of +/- 2mm.
