Pre-insulated pipes
DELTA pre-insulated pipes are a safe and efficient solution for the transmission of hot and cold domestic water, as well as for heating medium distribution. The carrier pipe diameters range from 20 to 160 mm, enabling versatile applications. The pipes are manufactured in accordance with PN-EN 15632-1 and 3 standards.
The PE foam filling and corrugated polyethylene (PE-HD) protective casing make the pipes flexible and resistant to mechanical damage during installation and when routing around obstacles. The flexible construction also significantly reduces installation time.
The insulation layer made of chemically cross-linked polyethylene foam with low air conductivity minimises heat losses during fluid transfer. As a result, this solution is energy-efficient and environmentally friendly.

DISCOVER ALL ADVANTAGES OF DELTA
VERSATILITY
Reliable transport of domestic hot water and heating medium for connecting residential houses, individual cooling networks and biogas plant installations.
Temperature resistance up to 95°C enables the pipe to be used in a wide range of heating applications with variable heat sources.
The carrier pipe is available in diameters ranging from 20 to 160 mm, forming a complete system with performance tailored to the needs of each customer.
Pipes are supplied in coils with a maximum length of 100 m. Custom pipe lengths can also be manufactured according to individual project requirements.
SECURITY
High pressure resistance of both PEX-a and PE pipes ensures safe and reliable operation of the pipeline throughout its entire service life.
Dezincification-resistant brass fittings are approved by hygienic certification for the transmission of drinking water.
Resistance to soil pressure and additional surface loads provides durability even in demanding ground conditions.
The outstanding service life of the installation is ensured by the high-quality components used in the DELTA system, guaranteeing long-term comfort and reliability.
A dedicated identification marker facilitates future contact with the system manufacturer in the event of pipeline modification or expansion.
SAVINGS
Low value of the thermal conductivity coefficient,
provides measurable savings in the process operation.The ability to self-compensate for thermal elongations.
Reduction of total assembly costs compared to traditional use pre-insulated pipes.
Ease of assembly
Elbows, sleeves and tees available pre-insulated to perform the necessary connections along the pipeline route allow for quick and easy to install directly in the trench.
Thanks to high flexibility and minimal bending radius from 0.25 to 1.26 m, the use of additional couplings for the obstacle avoiding during the pipeline laying process is not required.

Properties of the PEX-A line pipe
PEX-a carrier pipes are manufactured from specially selected material in accordance with PN-EN ISO 15875-1, 2 and 5 standards. During production, the material is extruded under high pressure and temperature in the presence of a chemical catalyst. A cross-linking process compliant with ISO 10147 is also applied, resulting in the formation of permanent three-dimensional molecular bonds. This 3D network structure allows the pipe to behave as a single molecular system, providing exceptional strength and durability.
Pipes designed for heating medium transmission are additionally equipped with an external EVOH oxygen diffusion barrier in accordance with DIN 4726.
Advantages of PEX-a polyethylene:
- Temperature resistance from –50°C to +95°C
- Corrosion resistance
- Outstanding mechanical strength
- Excellent chemical resistance
- Very long service life
- Resistance to scale build-up and flow reduction
