IVAR Alpex - Duo XS disc 32 x 3, 83532201

Product detailed description

IVAR Alpex - Duo XS 32 x 3 mm PE-AL-PEX pipe is commonly used in residential and commercial buildings for domestic hot water distribution, central heating systems and underfloor heating applications. Installers working in these sectors often encounter requirements for materials that ensure long-term performance, thermal stability and hygiene. This pipe provides a reliable solution for such installations, especially in systems requiring flexibility and resistance to thermal expansion. Its structure combines the benefits of polyethylene with the structural integrity of an embedded aluminium layer, making it suitable for both rigid and flexible layouts.

The pipe is supplied in a 50 m coil and is designed for use with mechanical compression or press fitting techniques. It is essential to verify the compatibility of fittings and tools before installation to ensure leak-free connections. The material composition allows for easy handling during installation while maintaining durability under operational conditions. It is particularly suited for systems where thermal expansion and contraction are expected due to frequent temperature fluctuations.

Technical parameters

Material	polyethylene
Operating temperature	+95 °C
Manufacturer	Franskische
Nominal pressure	PN 10
Pipe type	PE-AL-PEX
Weight	0.358 kg
Code	83532201

The nominal pressure rating of PN 10 indicates the pipe is suitable for low-pressure systems operating at temperatures up to +95 °C. The operating temperature limit defines the maximum heat exposure the pipe can withstand without degrading. These parameters are critical for correctly dimensioning the system and selecting appropriate fittings and accessories. The material composition ensures the pipe remains stable under these conditions while maintaining flexibility for routing around obstacles.

Installation and connection

Installation of IVAR Alpex - Duo XS requires the use of TA, RA crimping tools or press fittings. The connection process involves preparing the pipe end by removing the outer PE layer and inserting it into the fitting. A crimp ring or press tool is then used to secure the connection. It is important to ensure the pipe is cut straight and free of burrs before insertion. Common installation errors include incorrect crimping pressure, misalignment of the fitting and failure to clean the pipe surface before connection. Installers should verify that the correct tool is used for the specific fitting type and that the pipe is fully inserted into the fitting body. A visual inspection after installation helps identify potential issues such as gaps or uneven crimping. Regular checks during installation help prevent leaks and ensure system integrity.

Compatibility and accessories

This PE-AL-PEX pipe is compatible with standard TA and RA crimping systems as well as press fittings designed for PE-AL-PEX materials. To complete the installation, additional components such as valves, manifolds, insulation and expansion joints may be required depending on the system design. Accessories such as pipe clamps and supports should also be considered to manage thermal movement and prevent stress on the connections.

Technical background for designers

IVAR Alpex - Duo XS is a three-layer composite pipe consisting of polyethylene, an embedded aluminium layer and a second polyethylene layer. The aluminium core provides structural rigidity and minimises thermal expansion, while the PE layers offer chemical resistance and flexibility. This construction makes the pipe suitable for both hot and cold water applications. In heating systems, the pipe integrates seamlessly with radiators, underfloor heating mats and circulation pumps. The service life and efficiency of the system depend on proper installation, correct sizing and the use of compatible fittings. The pipe’s thermal conductivity is influenced by the aluminium layer, which helps maintain consistent heat transfer in underfloor heating systems. Designers should account for these properties when planning layouts and calculating pressure drops.

Service and operation

Routine maintenance for IVAR Alpex - Duo XS includes periodic inspections of connections for signs of wear, leakage or corrosion. As the system operates without internal coatings or additives, it is important to ensure the water quality remains within acceptable limits to prevent scaling or chemical degradation. No regular service intervals are specified for this product; however, any visible damage or performance issues should be addressed immediately.
