Pipe in conduit white 15x2.5 25/20 200m Uponor Combi Pipe 1033081

Universal multilayer pipe for water supply and heating installations

The Uponor Combi Pipe in a white protective sleeve is a comprehensive solution for water and heating installations, combining flexibility and durability. Available in a length of 200 meters, a diameter of 15 mm and a wall thickness of 2.5 mm, it is ideal for both new installations and modernization of existing ones. The four-layer construction ensures reliability and long-term operation.

Construction and properties

The Combi Pipe consists of several layers that provide its unique properties: an inner layer made of PE-Xa (cross-linked polyethylene), a middle layer of EVOH (ethylene vinyl alcohol), and an outer layer also made of PE-Xa. This combination of materials guarantees resistance to high temperatures (up to 95°C for short periods) and a working pressure of up to 10 bar at 20°C. The anti-diffusion barrier minimizes the risk of oxygen penetration into the installation, which is particularly important in heating systems. The flexibility of the pipe (minimum bending radius 120 mm) makes installation easier even in difficult conditions.

Application and benefits

The Uponor Combi Pipe with a protective sleeve is used in:

• Water supply installations – both hot and cold domestic water.
• Central heating systems – floor, radiator and low-temperature systems.
• Chilling installations.
• Rainwater systems.

Using the pipe in a protective sleeve provides additional mechanical protection during transport and installation, and also makes it easier to run the installation in hard-to-reach places. Fittings with a diameter of 25 mm allow for quick and tight installation using crimp or compression fittings. The coefficient of thermal expansion at 0.14 mm/(m.K) minimizes stresses in the installation caused by temperature changes. The white color of the pipe makes it easier to identify in the installation and looks aesthetically pleasing in visible places.
