Multilayer pipe - 40x3,5; PN10, T=+95° C - 5m rods IVAR.ALPEX-DUO XS

Product detailed description

Multilayer pipes such as the PE-AL-PEX type are commonly used in central heating systems, domestic hot water distribution, and underfloor heating applications. These systems require reliable, flexible piping that can withstand thermal expansion and maintain integrity over time. Installers working in residential, commercial and industrial settings frequently handle these materials during system design and retrofit projects. Accurate measurement, proper alignment and secure connections are essential to ensure long-term performance.

Due to their layered construction, these pipes combine the flexibility of plastic with the strength of an aluminium core. This makes them ideal for complex routing around obstacles and through tight spaces. When selecting and installing, professionals should consider the system’s operating conditions, including temperature fluctuations and pressure requirements, which influence the pipe’s suitability and longevity.

Technical parameters

Material	Polyethylene
Operating temperature	+95 °C
Manufacturer	Franskische
Nominal pressure	PN 10
Type of pipe	PE-AL-PEX
Weight	0.543 kg
Code	83540005
Brand	IVAR

The operating temperature of +95°C indicates that the pipe is suitable for hot water and heating applications within standard domestic and commercial systems. The nominal pressure of PN10 means that the pipe is designed to handle internal pressures up to 10 bar under normal operating conditions. These parameters are critical when determining compatibility with existing system components and when calculating system capacity and load.

Installation and connection

During installation, the pipe should be cut cleanly using a suitable pipe cutter to ensure flat, burr-free ends. The connection method typically involves crimping or compression fittings, depending on the system design and component specifications. Ensure that the correct fitting size matches the outer diameter of the pipe. Common mistakes include misalignment between pipe and fitting, insufficient tightening of crimp rings, and failure to account for thermal expansion. Always verify that the connection is leak-free after assembly and before system activation.

Compatibility and accessories

This PE-AL-PEX pipe is compatible with standard heating and hot water systems that utilise similar multilayer piping configurations. For complete installation, additional components such as fittings, valves, insulation and expansion compensation devices may be required. These should be selected based on the specific system layout and operational requirements. Accessories such as pipe clips and insulation sleeves help manage heat loss and mechanical stress.

Technical background for designers

The PE-AL-PEX construction consists of three layers: an inner and outer layer of cross-linked polyethylene (PEX) and a middle layer of aluminium. This combination provides good thermal conductivity while maintaining the flexibility of plastic. The presence of the aluminium layer also prevents oxygen diffusion into the system, reducing the risk of corrosion in metal components. Integration into the system requires consideration of expansion joints and support points to accommodate movement due to thermal changes. Longevity depends on proper installation, avoiding excessive bending or mechanical damage, and maintaining correct pressure and temperature limits.

Service and operation

Routine visual inspections are recommended to identify signs of wear, leakage or deformation. Any irregularities should be addressed immediately to prevent further damage. During operation, ensure that the system does not exceed the specified temperature and pressure limits. In case of suspected issues, the system should be depressurised and inspected by qualified personnel. There are no specific service intervals provided for this product; however, adherence to standard maintenance practices is advised.

Frequently asked questions

Can the PE-AL-PEX pipe be used for both heating and hot water systems?
Yes, the operating temperature of +95°C makes it suitable for both heating and hot water applications within the specified pressure range.

What fitting types are suitable for connecting this pipe?
Compression or crimp fittings are commonly used. Always ensure that the fittings match the pipe’s outer diameter and are compatible with the system’s operating conditions.

Is it possible to bend the pipe manually without special tools?
Manual bending is not recommended. The pipe should be bent using appropriate tools to avoid kinking or damaging the layers, especially in tighter bends.

Does the pipe require insulation in all installations?
Insulation is recommended in exposed runs to reduce heat loss and prevent condensation, particularly in unheated areas such as basements or crawl spaces.
