VESBO STABI V-CENTRO SDR6 pipe - PN20 FI 25mmx4.2mm /4m/ SCV25-V

PP-R pipe for water and heating installations – reliability and durability

VESBO STABI V-CENTRO SDR6 PN20 pipe with a diameter of 25mm and a wall thickness of 4.2mm is an element of an internal installation system, designed for transporting hot and cold domestic water and heating media. Made of polypropylene (PP-R) with a centrally located aluminum layer, it provides high resistance to pressure and temperature, and also minimizes oxygen diffusion into the installation. This solution is particularly important when working with metal elements, protecting them from corrosion.

The V-CENTRO pipe stands out from the competition with its unique construction – the centrally located aluminum layer eliminates the need to remove it before welding, which significantly speeds up and simplifies installation. This saves installers time and minimizes the risk of errors. This is a product you will not find in the offer of other manufacturers.

Construction and properties

The pipe construction is based on three layers: inner and outer layers of polypropylene PP-R type 3 and a central layer of aluminum with a thickness of 120 microns. The aluminum is joined end-to-end, creating an anti-diffusion barrier that prevents oxygen from penetrating the installation. This feature is crucial for protecting the components of the central heating installation from corrosion. Additionally, the pipe is characterized by a low linear expansion coefficient (0.03 mm/(m.K)), which translates into installation stability with temperature changes. Wall roughness at 0.007 mm ensures smooth medium flow, minimizing pressure losses and preventing scale build-up.

Application and benefits

VESBO STABI V-CENTRO PN20 pipe is used in:

• Central heating installations (CH)
• Hot and cold domestic water installations (DHW)
• Underfloor heating systems
• Industrial installations (transport of chemicals)

Benefits for the installer:

• Quick and easy installation – no need to remove aluminum before welding.
• High-quality connections – guaranteed tightness and durability thanks to the anti-diffusion layer.
• Time saving – shorter installation time thanks to the innovative pipe design.
• Versatility – can be used in various types of installations.

Benefits for the user:

• Durability and reliability – resistance to corrosion and high pressure ensures long-term use without failure.
• Quiet operation – smooth inner surface minimizes water flow noise.
• Hygiene – physiologically inert material does not affect the quality of drinking water.
• Energy saving - low thermal conductivity limits heat loss in the CH installation.
