PE-RT Pipe with EVOH oxygen barrier in corrugated sleeve
The pipe is classified for Class 1 at 8 bar, Class 2 at 8 bar, Class 4 at 10 bar and Class 5 at 8 bar, which covers hot water supply as well as heating circuits. The class chosen for the installation sets the design conditions, so check it against the technical data sheet before specifying the pipe for a given service.

Description and application
PE-RT pipe with EVOH oxygen barrier in corrugated sleeve is a three-layer PE-RT pipe running inside a protective sleeve. It is used in pipe-in-pipe systems for heating and water distribution from a manifold. The barrier keeps oxygen out of closed circuits, and the sleeve lets a damaged pipe be pulled out and replaced without opening the wall or floor.
PE-RT pipe with EVOH oxygen barrier in corrugated sleeve is a three-layer PE-RT pipe supplied already inside a corrugated protective sleeve. The pipe conforms to EN ISO 22391-2 and DIN 4726. Its maximum operating pressure is 8 bar and its maximum operating temperature is 70 °C. It is classified for application classes 1, 2, 4 and 5. The EVOH layer is an oxygen barrier. It stops oxygen from passing through the pipe wall into a closed heating circuit, which protects boilers, heat pumps, pumps, valves and other costly equipment connected to the system from oxidation and corrosion. The pipe comes in Ø16x2.0 mm in 100 m coils, in red or blue for hot and cold lines. A single length can run from the manifold to the outlet, round bends and through walls and floors, so fittings are only needed at the two connection points. This is a pipe-in-pipe system. The pipe is laid in walls, screeds and floors inside its sleeve, and each line is run separately from a central manifold to a wall box or an emitter. The sleeve protects the pipe during building work and in service. If a line is ever damaged, it can be pulled out of the sleeve and a new pipe pushed in without breaking open the structure. For this to work, the sleeve must be fixed securely to the structure close to the manifold and the wall boxes, and runs should have gentle bends. Connections are made with fittings designed for 16x2.0 PE-RT pipe.

Questions
- Why should I use a PE-RT pipe with an EVOH oxygen barrier in a closed heating circuit with a boiler, pump and radiators?
- A PE-RT pipe with an EVOH oxygen barrier stops oxygen from passing through the pipe wall into a closed heating circuit. This protects the boiler, heat pump, pump, valves and other metal parts from oxidation and corrosion. The EVOH layer is part of the three-layer pipe wall, and the pipe conforms to EN ISO 22391-2 and DIN 4726.
- Can the PE-RT pipe in a corrugated sleeve be pulled out and replaced if it gets damaged inside a concrete floor or wall?
- Yes. The PE-RT pipe in a corrugated sleeve can be pulled out of its sleeve and replaced with a new pipe, so the wall or floor does not have to be opened. For this to work, the sleeve must be fixed securely near the manifold and the wall boxes, and the run should avoid tight bends. A qualified installer should isolate, drain and replace the line, then pressure-test it before the system goes back into service.
- Which application classes and pressures is the 16x2.0 sleeved PE-RT EVOH pipe rated for in heating and hot water systems?
- The 16x2.0 sleeved PE-RT EVOH pipe is classified for Class 1 at 8 bar, Class 2 at 8 bar, Class 4 at 10 bar and Class 5 at 8 bar under EN ISO 22391-2. The stated maximum operating pressure is 8 bar and the maximum operating temperature is 70 °C. The technical data sheet gives the full conditions for each class.
- Is the sleeved PE-RT pipe with EVOH barrier suitable for hot and cold water lines from a manifold in an apartment building?
- The sleeved PE-RT pipe with EVOH barrier is classified for Class 1 and Class 2, the hot water supply classes of EN ISO 22391-2, so it can carry hot and cold water from a manifold. Whether it can be used for drinking water depends on the hygiene approval required in the country of installation. Please confirm the approval status with us before specifying it for potable water.
- How is a 100 m coil of sleeved PE-RT pipe laid between a manifold and wall boxes, and where are fittings needed?
- A 100 m coil of sleeved PE-RT pipe is laid as one continuous run from the manifold to the wall box or emitter, so fittings are only needed at the two ends. The pipe goes through walls, round corners and across floors inside its sleeve without intermediate joints. The ends are connected with fittings designed for Ø16x2.0 PE-RT pipe.
