Double insulated pipe AustroPUR double A175-2x32 – efficiency and durability in central heating systems

AustroPUR double A175-2x32 pipe is an advanced solution for central heating installations, combining the insulating properties of PUR foam with the strength and flexibility of PE-Xa pipes. The double-layer construction ensures minimal heat loss and makes the system exceptionally energy efficient. It is an ideal choice for both professional installers and customers who value comfort and savings.

Construction and application

The pipe consists of two PE-Xa (cross-linked polyethylene) conductive pipes, surrounded by a layer of polyurethane (PUR) insulation. The whole is protected by a layer of cross-linked XPE with a closed-cell microcellular structure and a corrugated outer layer made of HDPE (high-density polyethylene). This construction guarantees not only excellent insulating properties, but also high resistance to mechanical damage and corrosion. The return pipe is clearly marked, which facilitates correct installation and connection of the end pieces. The pipe is intended for transporting hot water in central heating installations, and its flexibility allows it to be adapted to complex installation systems.

Product advantages

• Excellent thermal insulation: PUR foam minimizes heat loss, reducing the operating costs of the heating system.
• High flexibility: Allows easy routing of pipes in difficult conditions, without the need for additional fittings.
• Corrosion resistance: PE-Xa pipes are resistant to corrosion, ensuring long-term reliability of the installation.
• Low weight: Facilitates transport and installation of pipes.
• EVOH anti-diffusion barrier: Prevents oxygen from penetrating the installation, protecting it from corrosion from the inside.
• Quick and safe installation: Marking of the return pipe facilitates correct connection of the end pieces.
• Long service life: The use of high-quality materials guarantees long-term operation of the system.
• Ecological production process: The production of pipes is carried out with respect for the natural environment.
• Factory cut to size: Availability of pipes cut to size avoids material waste and speeds up installation.

AustroPUR double A175-2x32 pipe is characterized by a maximum working pressure of 6.6 bar at +95°C and a maximum operating temperature of +95°C. PE-Xa pipes have an SDR 11 parameter, which indicates their mechanical strength. The system is compatible with various installation solutions and can be used both in new buildings and during the modernization of existing heating systems.
