Pipe IVAR.PE-Xa, 17 x 2, 600 m

Product detailed description

This cross-linked polyethylene (PEX) pipe is commonly used in low-temperature radiant floor heating systems in residential and commercial buildings. Installers typically work with this pipe during underfloor heating layout projects, where thermal distribution requires flexible yet durable piping that can withstand repeated thermal cycles and maintain structural integrity over time. The pipe is suitable for embedding in screeds, under tiles,木地板 or suspended floors, where it operates efficiently within pre-defined pressure and temperature limits.

The IVAR.PE-Xa pipe is sized to allow for efficient heat transfer while maintaining long-term resistance to internal corrosion and chemical degradation. It is often part of a closed-loop system that circulates heated water from a boiler or heat pump. Due to its flexibility, it allows for precise routing around obstacles and tight spaces, making it ideal for complex floor plans and retrofit projects.

Technical parameters

Installation and connection

The installation process involves unrolling the pipe from the 600 m coil and laying it in the required pattern—typically parallel or spiral—before securing it with clips or tapes. Connections are made using IVAR.TP or IVAR.RP crimp fittings with a dedicated crimper tool, or with IVAR.AC press fittings that require a hydraulic press. It is crucial to verify that the pipe ends are clean and free from burrs before fitting installation.

• Confirm that the crimp ring or press sleeve is fully seated and aligned with the pipe wall thickness.
• Check that the tool used matches the fitting size and type specified by the manufacturer.
• Ensure that the pipe is not bent beyond its minimum bending radius during routing.
• Avoid over-tightening of fittings, which may cause micro-cracks or deformation.

Compatibility and accessories

This PEX pipe is specifically compatible with IVAR.TP and IVAR.RP crimp fittings, and with IVAR.AC press fittings. To complete a full installation, additional components such as manifolds, valves, and insulation layers may need to be sourced separately. Installers must ensure that all components are from the same manufacturer range to guarantee system integrity and leak-free operation.

Technical background for designers

The IVAR.PE-Xa pipe is made of cross-linked polyethylene, a material known for its high flexibility and resistance to thermal expansion. The oxygen barrier layer prevents the diffusion of oxygen into the system, reducing the risk of oxidation-related corrosion in metal components such as pumps and valves. This material integrates well with standard heating circuits, especially those operating at medium temperatures and pressures. Long-term performance depends on proper sizing, correct installation, and avoiding exposure to UV light or sharp bends.

Service and operation

During regular system checks, inspect connections for signs of leakage or wear, particularly after long periods of operation. Ensure that the pipe is not exposed to mechanical stress or root intrusion in embedded applications. Since no specific service intervals are provided in the brief, routine visual inspections and pressure tests are recommended to confirm continued system integrity.

Frequently asked questions

Can IVAR.PE-Xa be used with press fittings?
Yes, IVAR.PE-Xa can be connected using press fittings from the IVAR.AC series. A hydraulic press tool is required for secure and leak-proof joints.

Is this pipe suitable for hot water supply systems?
No, this model is specifically designed for floor heating applications and does not meet the requirements for domestic hot water distribution systems.

What is the minimum bend radius for this pipe?
According to the manufacturer’s technical data sheet, the minimum bend radius must be maintained to avoid kinks and flow restrictions.

How many metres are available per reel?
Each reel contains 600 metres of pipe, and orders must be placed in multiples of this quantity due to packaging constraints.
