Pre-insulated pipe CALPEX DUO 63+63x182: Pex-a pipe 63x5.8+63x5.8mm, d182mm, 6 bar, 95°C, double, thermal insulation with PUR foam, with corrugated LLDPE outer jacket 1007315

Pre-insulated pipe for efficient heating and hot water installations

The CALPEX DUO pre-insulated pipe is an advanced solution for central heating and domestic hot water installations. The two-pipe (DUO) construction allows for simultaneous transport of heating and return medium in a single jacket, simplifying installation and reducing costs. Used in both new buildings and renovations, it performs well in low-temperature networks, connections to heat pumps, and district heating networks.

Construction and properties ensuring durability

The heart of the pipe is cross-linked polyethylene PEX-a with an EVOH anti-diffusion barrier, which prevents oxygen from entering the installation and protects against corrosion. The pipe is surrounded by high-quality, non-freon polyurethane (PUR) foam insulation, minimizing heat loss and ensuring high energy efficiency – the thermal conductivity λ is only 0.0199 W/m*K (at an average temperature of 50°C). The whole is protected by a corrugated outer jacket made of LLDPE polyethylene, resistant to mechanical damage, moisture and UV radiation. The corrugation increases the flexibility of the pipe, making it easier to lay in difficult conditions.

Key advantages for installers and users

• High flexibility: Facilitates routing of installation routes, even in tight spaces.
• Low heat loss: Significantly reduces heating costs thanks to PUR insulation.
• Corrosion resistance: The EVOH barrier protects the installation from the effects of oxygen.
• Strength: The pipe withstands working pressure up to 6 bar at a temperature of 90°C and short-term peaks up to 95°C.
• Easy installation: The DUO two-pipe construction simplifies connections and reduces installation time.
• Durability: High-quality materials guarantee a long system life.
• Versatility: Suitable for various applications – from single-family homes to district heating networks.
• Savings: Reduced heat loss translates to lower heating bills.

Technical specifications

The CALPEX DUO 63+63x182 pipe is characterized by the following dimensions: nominal diameter DN50, outer diameter of the conduit pipe 63 mm (wall thickness 5.8 mm), and the outer diameter of the entire pre-insulated pipe (with PUR foam and jacket) of 182 mm. This combination of parameters ensures an optimal balance between performance and size. The pipe is available for sale by the meter, allowing for precise adaptation to the needs of a specific installation.
