Twin Wall

Materials Used: Stainless Steel 304 BA (EN1.4301 - L20), Stainless Steel 316 BA (EN 1.4404 - L50) and Copper.

Inner Wall: Stainless Steel 316 BA (EN 1.4404 - L50) 0.5 mm thick.

Outer Wall: Stainless Steel 304 BA (EN 1.4301 - L20) thickness 0.5 mm or Copper 0.6 mm thick.

Insulation: Rock wool, thickness 25 mm, density 90 kg / cubic meter.

Plate: Stainless Steel 304 BA (EN 1.4301 - L20) or Copper, thickness 2.0mm.

Welding: longitudinal TIG process for the fusion of adjoining pieces, without filler.

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

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

Static intermediate support of a Chimney System or a Flue for conveying and evacuation in open air of the products resulting from the combustion processi (gases, smoke) of natural gas, diesel, wood and mulit-fuel.

For the designation of the Chimney System according to UNI EN 1856-1 the following is allowed:

operation:
- Dry (D)
- Wet (W)

pressures:
- Positive (P1 = 200 Pa)
- Negative (N1 = 40 Pa).

Operating temperatures:
- ≤ 200 ° C with silicone gasket and P1 = 200 Pa

- ≤ 600° C without silicone gasket and N1 = 40 Pa
