IVAR Alpex Isol disc 32 x 3; 9 mm, 806751025

Product detailed description

This IVAR Alpex Isol pipe is commonly used in residential and commercial buildings for heating and potable water distribution. Installers and technicians use it in underfloor heating systems, radiator circuits, and domestic hot and cold water lines. The PEX-AL-PEX composite design ensures flexibility and thermal stability, making it ideal for systems requiring expansion and contraction resistance. The insulation layer provides additional protection against heat loss and mechanical damage, particularly in concealed installations such as wall cavities or beneath flooring.

Correct installation is crucial for long-term performance. The pipe must be cut cleanly and prepared for connection using either crimping tools with IVAR TA, RA fittings or press-fit fittings from the IVAR PT range. The insulation thickness of 6 mm or 9 mm must remain intact during installation to maintain thermal efficiency. Installers should ensure the pipe is routed without sharp bends and supported at regular intervals to prevent sagging or stress points.

The nominal pressure rating of PN 10 indicates that the pipe is suitable for low-pressure systems typically found in domestic and light commercial applications. The maximum continuous operating temperature of +95 °C makes it appropriate for heating systems and hot water supply. These parameters are essential for determining correct sizing and ensuring compatibility with system design loads and temperature conditions.

Installation and connection

For secure connections, the pipe is joined using either crimping or press-fit methods. Crimping requires a compatible tool and fittings from the IVAR TA or RA series. Press-fit connections use the IVAR PT range and require a suitable pressing tool. The connection size must match the fitting specifications. During installation, ensure the insulation layer is not damaged and that the pipe is free from kinks. Common mistakes include incorrect tooling, mismatched fittings, and failure to support the pipe adequately after installation, which can lead to leaks or structural failure.

Compatibility and accessories

This pipe is designed to work with IVAR TA, RA crimp fittings and IVAR PT press-fit fittings. When planning an installation, ensure all required fittings are available for the chosen connection method. Accessories such as insulation tape or protective sleeves may also be needed for exposed runs or areas with potential mechanical impact. The PEX-AL-PEX construction ensures compatibility with standard heating and water system components.

Technical background for designers

The PEX-AL-PEX construction combines cross-linked polyethylene layers with an aluminium core. This design provides high flexibility while maintaining structural rigidity and thermal conductivity. The insulation layer is made from polyurethane foam with a low-density polyethylene outer sheath, offering thermal and mechanical protection. The system integrates well with underfloor heating, radiators, and water circuits. Long-term performance depends on proper installation, avoiding over-bending, and maintaining correct operating pressures and temperatures.

Service and operation

No specific maintenance is required for this pipe during normal operation. Regular checks should be performed for signs of mechanical damage, kinks, or insulation degradation. In the event of a leak or failure, the affected section should be replaced. The pipe is not designed for disassembly once installed, so any repairs require cutting out the faulty segment and rejoining with new fittings.

Frequently asked questions

Can IVAR Alpex Isol pipe be used for potable water?
Yes, it is suitable for potable water supply due to its non-toxic materials and compliance with relevant standards.

What tools are required for crimping connections?
A crimping tool compatible with IVAR TA or RA fittings is required, along with the appropriate crimp rings and fittings.

Is the insulation layer removable for repairs?
No, the insulation layer is part of the pipe construction and cannot be removed without damaging the integrity of the pipe.

Can this pipe be used in radiant floor heating systems?
Yes, it is suitable for underfloor heating applications due to its flexibility and thermal stability.
