Stainless steel chimneys for gas- and liquid-fuel boilers—where flue-gas and condensate tightness are critical
Stainless steel chimneys are used on gas- and liquid-fuel boilers. Flue-gas and condensate tightness are essential. They are manufactured from galvanized sheet, aluminum, 304 or 316L stainless steel; gas appliances typically use 316L (0.4–1 mm) with screw, spot or argon welding.
Assembly options include threaded, welded, seamed and locking systems. Single- or double-wall designs with non-combustible insulation are available for operating temperatures up to 450°C (peaks to 600°C). Condensate should be collected, neutralized when required and discharged safely—not into brick flues without proper lining.
