Pre-insulated pipe FLEXSTAR UNO 32x70: Pex-a pipe 32x2.9mm, d70mm, 6 bar, 80°C, single, thermal insulation with PUR foam, with corrugated LLDPE outer jacket 1091668

Pre-insulated pipe for efficient heating installations

The FLEXSTAR UNO pre-insulated pipe is a modern solution for heating installations, especially in heat pump systems and district heating networks. It is characterized by high flexibility and excellent insulation parameters, which translates to minimal heat loss and efficient operation of the entire system. It is a product of the Swiss company BRUGG, known for its high quality and reliability.

Construction and properties

The pipe consists of several key elements that provide its unique properties:

• Inner pipe: Made of cross-linked polyethylene PE-Xa with an EVOH anti-diffusion barrier, protecting against oxygen penetration and corrosion of installation elements. This ensures long-term system reliability.
• Thermal insulation: Made of polyurethane foam (PUR), which is characterized by a very low thermal conductivity coefficient (0.201 W/(m.K)), minimizing energy losses.
• Outer jacket: Durable and resistant to mechanical damage jacket made of LLDPE polyethylene, corrugated for easy installation and resistant to UV radiation. Gray color provides good visibility on the construction site.

Thanks to its construction, the FLEXSTAR UNO pipe is resistant to temperatures up to 80°C (continuous operation) and 95°C (intermittent operation) and operating pressure up to 6 bar. The standardized dimension ratio (SDR) is 11, which guarantees adequate mechanical strength.

Application and benefits

The FLEXSTAR UNO pipe is used in:

• Heating supply installations for residential and commercial buildings.
• Modernization of existing heating systems.
• Air-to-water heat pump networks.
• Local district heating networks.
• Connections between buildings (house-house).

Why choose FLEXSTAR UNO?

• Easy installation: The flexible construction of the pipe allows it to be laid even in tight spaces without the need for additional elbows, which speeds up installation work and reduces costs.
• Low heat loss: Thanks to the high-quality PUR insulation, energy losses are minimized, which translates to lower heating costs.
• Durability and reliability: The materials used and compliance with DIN EN 15632-2 and DIN 4726 standards guarantee long-lasting and trouble-free operation of the system.
• Corrosion resistance: The EVOH anti-diffusion barrier protects metal elements from corrosion, extending the life of the entire installation.
• Flexibility: Small bending radius (0.3 m) makes it easier to lay the pipe in difficult conditions.
• Availability: The pipe is available cut to length, allowing for precise adaptation to the needs of a specific project – no need to order full coils and generate material waste.

The FLEXSTAR UNO pipe is an investment in the comfort, savings and reliability of the heating system. Its technical parameters and ease of installation make it an ideal choice for both professional installers and end customers looking for efficient heating solutions.
