IVAR Alpex Isol disc 16 x 2; 9 mm, 806171950

Product detailed description

This PEX-AL-PEX pipe is suitable for installation in residential, commercial and industrial buildings. It is commonly used in underfloor heating systems, radiator circuits and hot water supply lines. The pipe allows for both pre-fabricated and on-site assembly, depending on the fitting method selected. Its thermal insulation layer reduces heat loss and maintains consistent temperatures within the system.

The insulation jacket consists of low-density polyethylene with a protective layer, ensuring mechanical durability and resistance to external environmental factors. The core construction includes a cross-linked polyethylene outer layer, an aluminium middle layer for structural stability and a polyethylene inner layer. This combination provides flexibility, kink resistance and long-term performance in pressurised systems.

Technical parameters

Material	Polyethylene pipes

The operating temperature limit of +95°C means the pipe is appropriate for central heating and hot water systems but not for high-temperature industrial applications. The PN 10 pressure rating indicates suitability for standard residential and light commercial pressure levels. The PEX-AL-PEX construction ensures dimensional stability and resistance to thermal expansion over time.

Installation and connection

This pipe can be connected using the IVAR.TA or IVAR.RA series threaded fittings or through press fittings such as those in the IVAR.PT and IVAR.PPSU series. The connection process requires careful alignment and proper tooling to ensure a leak-free joint. Before installation, verify that the insulation jacket is undamaged and that the pipe is free from kinks or bends that could restrict flow. Installers should also confirm that the insulation jacket thickness remains intact during cutting and that the cut end is cleaned before attaching any fittings. Common mistakes include improper tool calibration, which can result in incomplete sealing, and incorrect bending radius that compromises the pipe’s integrity. Always support the pipe along its length to avoid sagging and maintain even distribution of load.

Compatibility and accessories

The pipe is compatible with the IVAR.TA, IVAR.RA series threaded fittings and the IVAR.PT and IVAR.PPSU press fitting series. To complete the system, additional components such as valves, manifolds and insulation tapes may be required, depending on the design of the installation. Accessories should be sourced from the same manufacturer to ensure full compatibility and system integrity.

Technical background for designers

The PEX-AL-PEX construction combines the flexibility of cross-linked polyethylene with the rigidity of an aluminium layer, offering a balance between thermal efficiency and mechanical strength. The insulation jacket minimises heat transfer losses and prevents condensation on the outer surface. This makes it ideal for systems where energy efficiency and space constraints are critical considerations. The operating principle relies on uniform heat distribution through the pipe network while maintaining hydraulic balance.

Service and operation

During operation, regular inspection of the joints and insulation condition is recommended. Check for signs of wear, damage or discolouration on the insulation jacket. Ensure that all connections remain secure and that there is no visible leakage. If the pipe is exposed to sunlight or extreme environments, additional protection measures may be necessary. There are no specific service intervals outlined in the provided documentation.

Frequently asked questions

Can this pipe be used in both heating and drinking water systems?
Yes, the pipe is suitable for radiator heating and hot water distribution due to its construction and material properties.

What tools are needed for press fitting connections?
A certified pressing tool designed for the IVAR.PT and IVAR.PPSU series is required to ensure a secure and leak-free connection.

Is the insulation jacket removable after installation?
No, the insulation jacket forms part of the finished installation and should not be removed unless specifically required for repair or maintenance.

Can this pipe be bent manually without tools?
It is not recommended. Bending should be performed using an approved pipe bender to maintain the correct radius and prevent deformation of the structure.
