Pre-insulated pipe CALPEX DUO 50+50x162: Pex-a pipe 50x4.6+50x4.6mm, d162mm, 6 bar, 95°C, double, thermal insulation with PUR foam, with corrugated LLDPE outer jacket 1007314

Pre-insulated pipe CALPEX DUO 50+50x162 – an effective solution for modern installations

The CALPEX DUO 50+50/162 pre-insulated pipe is an advanced solution for building efficient and energy-saving heating and plumbing networks. Designed for durability and ease of installation, it is ideal for both new buildings and the modernization of existing installations. Thanks to the double pipe, it enables the simultaneous transport of two media – e.g., hot and cold domestic water – reducing costs and simplifying the system.

Construction and properties

The pipe consists of several key elements, ensuring its reliability and longevity: two inner pipes made of cross-linked polyethylene PEX-a (PE-Xa) with an EVOH anti-diffusion barrier, which prevents oxygen from penetrating the installation, which is particularly important in heating systems. Thermal insulation made of CFC-free polyurethane foam (PUR) minimizes heat loss, resulting in energy savings. The whole is surrounded by a corrugated outer jacket made of low-density polyethylene (LLDPE), which provides protection against mechanical damage and weathering. The corrugated surface makes it easier to lay the pipe and increases its flexibility.

• High thermal insulation: PUR foam ensures minimal heat loss, which translates into lower operating costs of the heating system.
• Corrosion resistance: The materials used to produce the pipe are resistant to the action of most chemical substances present in water and soil.
• Flexibility and ease of installation: The corrugated outer jacket makes it easier to route the pipe in difficult conditions, and the PEX-a material allows bending without the risk of damage.
• Durability: The use of high-quality materials guarantees a long service life of the pipe, even in demanding operating conditions.
• Double pipe: Enables the simultaneous transport of two media, reducing installation costs and simplifying the system.

Application and technical parameters

The CALPEX DUO 50+50/162 pipe is used in:

• Central heating networks in residential and commercial buildings.
• Domestic hot water installations.
• Heat pump systems (air-to-water).
• Local district heating networks.
• Repair of existing heating installations.

The pipe is characterized by the following parameters:

• Nominal diameter: DN40 + DN40
• Outer diameter: 162 mm
• Working pressure: 6 bar (at 90°C)
• Maximum momentary working temperature: 95°C
• Inner pipe material: PEX-a with EVOH barrier
• Insulation material: PUR (polyurethane)
• Outer jacket material: LLDPE (low-density polyethylene)

Thanks to the combination of these features, the CALPEX DUO 50+50/162 pipe is a comprehensive solution for professionals and individual customers looking for a reliable and efficient heating and plumbing system. It provides comfortable use for many years, minimizing operating costs and environmental impact.
