IVAR Alpex - Duo XS disc 18 x 2, 83518701

Product detailed description

IVAR Alpex - Duo XS is a composite pipe designed for use in residential and commercial buildings. It is commonly used in underfloor heating systems, central heating circuits and domestic hot and cold water distribution. The PE-AL-PEX structure provides flexibility during installation while maintaining structural integrity under thermal expansion and contraction. Installers should ensure correct routing and avoid sharp bends to maintain hydraulic performance.

The pipe is supplied in 200 m reels and is compatible with standard connection methods used in modern plumbing and heating systems. It can be integrated into both new constructions and renovation projects where reliable long-term performance is required. The white colour allows for easy visual inspection of connections and system integrity.

Technical parameters

The PN 10 rating indicates suitability for low-pressure applications such as domestic water and heating circuits. The maximum operating temperature of +95 °C makes it appropriate for warm water supply and radiator heating. The PE-AL-PEX construction combines flexibility with dimensional stability, reducing the risk of deformation under thermal stress.

Installation and connection

Installers should use TA or RA crimping tools or press fittings for secure connections. Ensure that all joints are clean and free from debris before fitting. Check that the pipe is not bent beyond its minimum bend radius, which is specified in the manufacturer’s guidelines. Common mistakes include improper tool calibration and incorrect crimping depth, which can lead to leaks or weak connections. Verify that the pipe is properly secured along its length, especially near joints and valves, to prevent movement-induced stress.

Compatibility and accessories

This pipe is compatible with standard crimping and press fitting systems. When installing, ensure that the correct type of fitting is selected based on the application requirements. Additional components such as insulation, expansion compensators and valves may be required depending on the system configuration. Related products should be selected according to the system design and local standards.

Technical background for designers

The PE-AL-PEX structure consists of a polyethylene inner layer, an aluminium reinforcement layer and an outer polyethylene layer. This combination offers good resistance to oxygen permeation and ensures long-term durability in wet environments. The material properties allow for easy handling during installation and reduce the need for additional supports in many applications. The system should be designed to account for thermal expansion, especially in large installations. Oxygen barriers within the pipe help prevent corrosion in metal components within the system.

Service and operation

Periodic checks should focus on the integrity of joints and the condition of the pipe surface. Look for signs of mechanical damage or discolouration that could indicate degradation. The system should be flushed periodically to remove sediment buildup. No specific service intervals are provided in the technical documentation.
