Flexible Stainless Steel Flue Pipes – Flexinox De Marinis

The Flexinox De Marinis stainless steel flexible pipes are designed for the renovation and construction of flue systems in complex environments where rigid ducts cannot be installed. The AISI 316L BA double‑wall stainless steel structure ensures high‑temperature resistance, long‑term durability and excellent adaptability to irregular or narrow installation paths.

Main Features

• AISI 316L BA stainless steel with high resistance to corrosion and acidic condensates.

• Double wall with smooth internal surface to improve draft and reduce pressure losses.

• Corrugated external wall for superior flexibility and an optimal bending radius.

• Operating range from -100°C to +700°C, suitable for high‑temperature generators.

• Compatible with low‑pressure installations (below 40 Pa) and condensate presence when used with dedicated joints.

• Effective vibration and noise absorption, ideal for connections to boilers, fireplaces and ventilation systems.

Recommended Applications

• Renovation of shafts and technical ducts with irregular paths.

• Installations in tight spaces or layouts with non‑linear bends.

• Connection between rigid pipes and combustion appliances.

• Systems requiring resistance to high temperatures and corrosive agents.

Accessories and Installation

To ensure compliance with current regulations, dedicated connection sleeves must be used between rigid and flexible pipes. These accessories are available within the De Marinis product range.
