Insulated chimney pipe 250 mm SOLINOX Ø130–180 (inox 316L/304)

The insulated chimney pipe SOLINOX with a 250 mm length (sandwich element) is designed for assembling modular flue systems with an inner diameter of Ø130 mm and an outer diameter of Ø180 mm. This format is often chosen for systems where it is important to retain flue-gas temperature, reduce the risk of condensate formation, and maintain stable draft under variable firing conditions.

The key design feature is the combination of two stainless-steel grades. The inner liner is made of AISI 316L, which offers improved resistance to aggressive combustion by-products and acidic condensate. This is especially relevant for solid-fuel boilers, fireplaces, and stoves, particularly when fuel is not always perfectly dry or the appliance operates under partial loads. The outer shell is made of AISI 304 — a robust stainless steel that resists corrosion and external influences, including humidity and temperature fluctuations. Between the two walls, a layer of thermal insulation reduces heat loss and lowers the outer surface temperature of the chimney, improving overall fire safety.

A 250 mm length is convenient when you need precise height adjustment, have to work around construction constraints, or neatly “make up” a distance between elements. The sandwich pipe can be used as part of vertical and horizontal runs (in accordance with the project and the manufacturer’s installation requirements/standards) and is compatible with typical insulated chimney components such as tees, inspection sections, supports, brackets, terminals, and diameter-matched adapters.

This element is a solid choice when you need a durable stainless-steel chimney with a clear functional logic: 316L inside for condensate and chemical resistance, 304 outside for weather and mechanical protection, and insulation for more stable draft and fewer issues from cooling/moisture in the flue. Suitable for private homes, bathhouses/saunas, boiler rooms, and any sites where neat installation and long service life matter.
