Pre-insulated pipe FLEXSTAR UNO 40x90: Pex-a pipe 40x3.7mm, d90mm, 6 bar, 80°C, single, thermal insulation with PUR foam, with corrugated LLDPE outer jacket 1091669

Pre-insulated pipe for efficient heating installations

The FLEXSTAR UNO pre-insulated pipe is a modern solution for heating installations, especially in combination with heat pumps and in local district heating networks. It is characterized by high flexibility, minimal heat loss and easy installation, which translates into saving time and costs. The system is designed with the requirements of modern construction in mind, ensuring reliability and long-term operation.

Construction and properties

The FLEXSTAR UNO pipe consists of several key elements that provide its unique properties. The core is made of cross-linked polyethylene PEX with an EVOH anti-diffusion barrier, protecting against oxygen penetration and corrosion of metal elements of the installation. Thermal insulation made of PUR foam minimizes heat loss – its thermal conductivity coefficient is 0.194 W/(m.K). The whole is surrounded by a corrugated outer jacket made of LLDPE, which provides mechanical protection and resistance to UV radiation. Such a construction guarantees high durability and reliability of the system.

The pipe is characterized by a small bending radius (0.3 mm), which makes it easier to lay even in tight spaces without the need for additional elbows. The standardized dimension ratio (SDR) is 11, and the maximum working pressure at 20°C is 15 bar – ensuring safe operation in various conditions. Additionally, the pipe has an anti-diffusion zone, increasing its resistance to moisture penetration.

Application and benefits

The FLEXSTAR UNO system is perfect for:

• Installations supplying heat to residential and commercial buildings.
• Modernization of existing heating systems.
• Small and medium-sized heat pump networks (air-to-water).
• Local district heating networks.
• Connections between buildings.

By choosing FLEXSTAR UNO, you gain:

• Energy savings: thanks to the high thermal insulation, the pipes minimize heat loss.
• Fast installation: the flexible construction makes it easier to lay pipes and reduces the number of connections.
• Durability and reliability: the use of high-quality materials guarantees long-term operation of the system.
• Corrosion resistance: the EVOH anti-diffusion barrier protects the metal elements of the installation against corrosion.
• Easy identification: a patented marking method makes it easier to identify pipes on the construction site.
• Possibility of cutting to size: the pipe is available cut to the meter, allowing for precise adaptation to the needs of the investment.
