IVAR Alpex - Duo XS rod 50 x 4, 83550005

Product detailed description

IVAR Alpex - Duo XS rods are commonly used in residential and commercial buildings for central heating, domestic hot water distribution and underfloor heating systems. These pipes are installed by heating and plumbing professionals who require reliable, long-lasting materials for hydronic systems. The PE-AL-PEX composite structure provides flexibility and resistance to thermal expansion, making it suitable for both new builds and renovation projects. The 50 x 4 dimensions are ideal for medium to large diameter circuits, ensuring efficient flow rates and reduced pressure loss in larger installations.

When working with this type of pipe, installers must consider the system’s operating conditions, including temperature and pressure levels. The PN 10 rating indicates that the pipe is suitable for standard domestic and light commercial applications. The operating temperature of up to 95°C makes it compatible with conventional heating systems, including those using radiators or underfloor heating. The PE-AL-PEX material combines the flexibility of polyethylene with the structural strength of an aluminium layer, ensuring dimensional stability and long-term performance.

Technical parameters

The PN 10 pressure rating means the pipe is suitable for systems operating at up to 10 bar nominal pressure. The maximum operating temperature of 95°C indicates it is appropriate for heating and hot water systems but not for high-temperature industrial applications. The PE-AL-PEX construction ensures that the pipe can be bent without kinking, which is important for routing through walls and under floors. These parameters are essential for correct system sizing and selection of fittings and accessories.

Installation and connection

Installation of IVAR Alpex - Duo XS rods involves cutting the pipe to length and connecting it using TA, RA or press fittings. The 50 mm outer diameter requires fittings compatible with this size. Installers should ensure that the pipe is free from kinks and that the ends are clean and square before fitting. Common installation mistakes include over-bending the pipe, which can cause stress fractures, or using incompatible fittings that may lead to leaks. It is important to follow the manufacturer’s guidelines for expansion compensation and support spacing to avoid mechanical stress over time.

Compatibility and accessories

This pipe is compatible with TA, RA and press fitting systems. To complete the installation, it is necessary to order the appropriate fittings and tools for the selected connection method. Accessories such as expansion loops, pipe clips and insulation should also be considered depending on the system design and local regulations. While no specific related products are listed, installers should ensure that all components are from the same manufacturer or compatible with the PE-AL-PEX material to avoid chemical incompatibility or mechanical failure.

Technical background for designers

The PE-AL-PEX construction consists of a polyethylene outer and inner layer with an aluminium layer in between. The pipe is suitable for both direct and indirect heating systems and can be integrated with conventional boilers, heat pumps or solar thermal systems. The service life is influenced by the operating conditions, particularly the temperature and pressure levels, as well as the quality of the installation and the use of compatible fittings.

Service and operation

During operation, the pipe requires no regular maintenance other than visual inspections for signs of damage or wear. Installers should check for leaks, especially at connection points, and ensure that expansion compensation is functioning correctly. There are no specified service intervals for this product, but it is recommended to inspect the system periodically as part of routine building maintenance. Any issues with the pipe or fittings should be addressed promptly to prevent system failure or water damage.
