Double pre-insulated pipe AustroPEX WPE A160-2xDN50 corrugated stainless steel pipe, for monoblock heat pumps, thermal insulation with PE foam, corrugated HDPE outer jacket PIP-XPH-160D50

Highly durable pre-insulated pipe for central heating and heat pump systems

This AustroPEX WPE twin-pipe pre-insulated pipe is designed for efficient central heating and monoblock heat pump systems. The construction with corrugated stainless steel 1.4404 (AISI 316L) inside, combined with high-quality PE foam insulation and an external HDPE jacket, ensures durability, minimal heat loss and easy installation. The pipe is particularly recommended for applications requiring corrosion resistance and high flexibility.

The pipe is versatile thanks to two empty ducts, which allow for convenient routing of control and power cables for the heat pump – all in one system. The corrugated surface of the external HDPE jacket makes it easier to lay the pipe, even in difficult installation conditions.

Construction and application

The AustroPEX WPE pipe consists of several key elements:

• Conducting pipes: Made of corrugated stainless steel 1.4404 (AISI 316L), providing high corrosion resistance and mechanical strength. The corrugation increases the flexibility of the pipe, making it easier to adapt to existing infrastructure.
• Insulation: Made of cross-linked PE foam (XPE) with a closed-cell structure, minimizes heat loss and water absorption (below 1% according to DIN 53428). This ensures that the installation maintains high energy efficiency for a long time.
• Protective jacket: A durable external jacket made of corrugated HDPE protects the insulation from mechanical damage and weathering. The corrugated surface also increases the flexibility of the pipe, making it easier to unroll and lay.
• Ducts: Two empty ducts allow for aesthetic and safe routing of control and power cables for the heat pump, eliminating the need for additional fastening elements.

The pipe is ideal for use in:

• Central heating systems (supply and return).
• Monoblock heat pump installations – a dedicated solution for efficient building heating.
• District heating networks – both local and municipal.
• Domestic water installations – thanks to corrosion resistance and high-quality materials.

Advantages for installers and users

• Fast installation: Flexible construction and corrugated jacket make it easier to lay the pipe, reducing installation time.
• High energy efficiency: Minimal heat loss thanks to XPE insulation translates into lower heating costs.
• Durability: Stainless steel 1.4404 (AISI 316L) ensures corrosion resistance and long installation life.
• Versatility: The ability to route control cables in ducts eliminates the need for additional fastening elements.
• Safety: The materials used to manufacture the pipe are safe for the environment and user health – free from FCFC, HCFCKW and HFKW.
• Cost savings: Minimised energy losses translate into lower heating bills for years to come.
