Pre-insulated pipe CALPEX UNO 40x91: Pex-a pipe 40x3.7mm, d91mm, 6 bar, 95°C, single, thermal insulation with PUR foam, with corrugated LLDPE outer jacket 1007299

Highly durable pre-insulated pipe CALPEX UNO 40x91 – an effective solution for heating and hot water installations.

The CALPEX UNO 40x91 pre-insulated pipe is a component of a pre-insulated pipe system, designed for the efficient transport of heat and domestic hot water in low-temperature installations. It is a single PEX pipe with a diameter of 40x3.7mm, surrounded by a layer of PUR foam insulation and protected by a corrugated outer jacket made of LLDPE. This construction ensures minimal heat loss, high resistance to mechanical damage and easy installation.

Construction and properties

The CALPEX UNO pipe consists of several key elements that ensure its reliability and efficiency:

• PEX pipe: Made of cross-linked polyethylene (PEX-a) with an EVOH anti-diffusion layer to prevent oxygen from penetrating the installation. This is crucial for protecting installation components from corrosion.
• PUR insulation: Freon-free polyurethane (PUR) foam provides excellent thermal insulation, reducing heat loss during medium transport.
• LLDPE jacket: A corrugated outer jacket made of low-density polyethylene (LLDPE) protects the pipe from mechanical damage, moisture and UV radiation. The corrugations make it easier to lay the pipe, especially in difficult conditions.

The pipe is characterized by high operating parameters – it withstands pressure up to 6 bar at a temperature of 90°C and short-term loads up to 95°C. This makes it ideal for use in central heating systems, underfloor heating and domestic hot water installations.

Application and benefits

CALPEX UNO pipes are widely used both in new buildings and during the modernization of existing installations:

• Supplying heat to buildings: Efficient transport of heat from the boiler room or heat pump to individual buildings.
• Heating network repairs: The possibility of replacing old pipes without the need to cut walls or floors thanks to the flexibility of the material.
• Small and medium-sized air-to-water heat pump networks: An optimal solution for systems using renewable energy sources.
• Local district heating networks: An economical and reliable way to supply heat to small estates or building complexes.

By choosing the CALPEX UNO pipe, you gain:

• Low heat loss: Energy savings and reduced heating costs.
• Corrosion resistance: The EVOH layer protects the installation from the effects of oxygen, extending its life.
• Easy installation: The flexibility of the pipe makes it easy to lay even in complex installation systems.
• Durability and reliability: High quality materials guarantee long-term use without failure.
• Versatility: Can be used in various types of heating and domestic hot water installations.
