Pipes
Pipes
Kuzeyboru pre-insulated pipes are manufactured in accordance with international standards (TS EN 253, TS EN 448, TS EN 12201-2+A1), offering high quality and user convenience. Developed using the latest technology, these pipes minimize heat loss to enhance energy efficiency while providing long-lasting and durable performance.
Reliable and Efficient Thermal Insulation
The polyurethane foam used between the carrier pipe and the outer casing absorbs thermal expansion stresses and transfers friction forces between the soil and the pipe to the carrier pipe. This eliminates the need for additional expansion compensators, resulting in a more efficient and cost-effective infrastructure solution.
Widely used in geothermal energy systems, hot water distribution lines, industrial facilities, and the marine industry, Kuzeyboru pre-insulated geothermal pipes deliver reliable performance with their high strength and superior insulation properties.
Key Features of Pre-Insulated Pipes
- High-Density Polyethylene (HDPE) Carrier Pipe: Offers excellent resistance to abrasion and chemicals.
- Polyurethane Foam Insulation: Thermal conductivity coefficient at 50°C is <0.026 W/(mK), providing outstanding heat retention.
- Protective Outer Casing: Made from high-density polyethylene, it ensures superior resistance to impact and external factors.
- Waterproof Closed-Cell Structure: Prevents water ingress for extended service life.
- High Thermal Resistance: Continuous operating temperature up to 120°C, with peak resistance up to 140°C.
- Compliance with TS EN 253 Standard: Foam core density ≥ 60 kg/m³, overall density ≥ 80 kg/m³, providing excellent mechanical strength through high compression and shear resistance.
- Heat Loss Rate: Just 1°C over 20 km, indicating high insulation performance.
Kuzeyboru pre-insulated geothermal pipes are the ideal solution for energy-efficient projects requiring durability, excellent thermal insulation, and long service life.

Frequently Asked Questions
An insulated pipe is a type of piping covered with special thermal insulation material to prevent heat loss and protect the pipe from external influences. Commonly used in central heating systems, geothermal energy projects, and industrial facilities.
Geothermal pipes are used to transport hot water in geothermal power plants, district heating networks, central hot water systems, greenhouses, and industrial applications.
Pre-insulated geothermal pipes, pre-insulated steel pipes, and high-temperature resistant PPRC or HDPE pipes are used. These ensure minimal heat loss due to their thermal insulation and temperature resistance.
Thanks to their resistance to heat and pressure, pre-insulated geothermal pipes have a service life of over 50 years. The insulating layer enhances durability and ensures long-term energy efficiency.
Pre-insulated steel pipes can continuously operate at 120°C and endure peak temperatures up to 140°C for short durations.
They consist of three layers: the carrier pipe (HDPE or steel), the insulation layer (polyurethane foam), and the outer casing (HDPE or metal sheathing).
Insulation thickness depends on the pipe’s diameter and the temperature of the transported fluid. Typically, polyurethane foam insulation ranges between 20 mm and 100 mm.
The outer casing protects the pipe from impacts, chemicals, and UV radiation. Made from HDPE or metal, it ensures a long service life for the pipe.
By minimizing heat loss, insulated pipes improve energy efficiency, reduce operational costs, and support sustainable energy usage.
