Ricom pipe straight piece PP-AL L1000 DN60/100 for ventilation and flue connections

Ricom pipe straight piece PP-AL L1000 DN60/100 is a straight transitional duct section designed for ventilation and flue connections that require a concentric or dual-diameter arrangement. Manufactured from polypropylene with an intermediate aluminum layer (PP-AL), this 1000 mm long section combines chemical resistance and light weight of plastic with improved stiffness and thermal stability provided by the metal layer. The component is intended for use in residential and light commercial HVAC and exhaust systems where a reliable transition between DN60 and DN100 pipes is needed.

Advantages

The PP-AL construction offers enhanced dimensional stability compared with single-material plastic pipes, reducing deformation at elevated temperatures and under mechanical load. Its polypropylene surfaces provide resistance to common condensates and many chemical agents found in ventilation and flue gas streams, while the aluminum layer increases rigidity and helps maintain concentric shape. The straight 1000 mm length simplifies installation by minimizing the number of joints and potential leak points.

Suitable for

• Concentric or transitional connections between DN60 and DN100 ducts
• Residential ventilation systems and exhaust extraction
• Light commercial HVAC installations requiring plastic–metal composite ducts
• Flue gas ducts where corrosion resistance and dimensional stability are required

Key specifications

• Material: polypropylene with aluminum intermediate layer (PP-AL)
• Length: 1000 mm
• Nominal diameters: DN60/100 (concentric/transition)
• Construction: straight pipe section for duct/flue connections
• Typical applications: ventilation and flue/exhaust systems in residential and light commercial settings

How to use

Fit the PP-AL straight piece between corresponding DN60 and DN100 duct components, ensuring concentric alignment where specified. Use compatible clamps, couplings or gasketed connectors recommended for PP-AL composite ducts to secure joints and maintain airtightness. Observe manufacturer instructions for axial insertion depths and joint sealing methods. Avoid excessive bending or mechanical stress on the section during installation to preserve the integrity of the aluminum layer and polypropylene surfaces.

Usage recommendations

For best performance, install the section in systems operating within the temperature and chemical exposure ranges specified for polypropylene and aluminium composite ducts. Inspect joints periodically for signs of wear or loosening, and replace the section if deformation or corrosion of the aluminum layer becomes apparent. Use appropriate supports at regular intervals to prevent sagging over long runs.
