Pipe IVAR.PE-Xa, 20 x 2, 200 m

Product detailed description

IVAR.PE-Xa pipes are commonly used in residential and commercial buildings for underfloor heating applications. They provide reliable distribution of heated water through thermally efficient cross-linked polyethylene. Installers typically handle pre-insulated manifolds, heat emitters and expansion joints, ensuring correct routing and avoiding sharp bends or mechanical stress.

The pipe is sized according to hydraulic requirements, considering flow rates and pressure drops across the circuit. The PN rating allows for safe operation within specified temperature ranges. Due to the minimum order quantity of 200 m, planning should account for complete circuit lengths to avoid waste or unnecessary joints.

Technical parameters

Nominal pressure	PN 6
Weight	0.116 kg
Code	71020700
Brand	IVAR

These pressure ratings define the maximum allowable working conditions. At +90°C, the pipe supports a nominal pressure of 6 bar (PN6), while at +60°C, it can handle up to 10 bar (PN10). This makes it suitable for low-temperature heating systems operating in typical domestic and light commercial environments.

Installation and connection

To connect the pipe, use IVAR.TP or RP crimp rings with a compatible crimper tool. Alternatively, press-fit connections with IVAR.AC fittings require a dedicated press machine. Ensure the internal diameter matches the fitting specifications and confirm that the oxygen barrier remains intact during cutting. Avoid over-tightening or misalignment when assembling joints, as this can cause leaks or premature failure. Check all connections visually after installation and perform pressure tests at operating temperature to verify integrity.

Compatibility and accessories

This pipe is compatible with standard floor heating components such as manifolds, valves and insulation boards. For secure connections, IVAR.TP, RP crimp rings or IVAR.AC press fittings must be used. Additional materials include insulation, fixing clips and expansion compensators, depending on the system design and local regulations.

Technical background for designers

The cross-linked polyethylene (PE-Xa) structure provides flexibility and resistance to thermal cycling. The oxygen barrier prevents corrosion in closed heating circuits by limiting oxygen diffusion into the system. When integrated into underfloor heating, the pipe's thermal conductivity and low linear expansion help maintain long-term efficiency. Designers should consider pipe spacing, insulation quality and system balancing to ensure even heat distribution and minimal energy loss.

Service and operation

During normal operation, monitor for signs of leakage, discolouration or unusual noises in the system. Inspect connections annually and re-press or re-crimp if necessary. No specific maintenance intervals are provided beyond routine visual checks.

Frequently asked questions

Can IVAR.PE-Xa be used with non-IVAR fittings?
It is recommended to use only IVAR.TP, RP or IVAR.AC fittings to ensure compatibility and sealing performance.

What is the minimum bending radius for this pipe?
To prevent damage, follow standard guidelines for PEX pipe bending based on the manufacturer’s technical data sheet.

Is the oxygen barrier sufficient for all heating fluids?
The oxygen barrier is suitable for use with glycol-based mixtures and water in standard underfloor heating systems.

Can this pipe be cut on-site?
Yes, but ensure clean, square cuts using a suitable tool to prevent burrs or deformation at the end.
