VESBO STABI V-CENTRO SDR6 pipe - PN20 DN50x8.3mm /4m/ SCV50-V

PP-R Pipes for Sanitary and Heating Installations

VESBO STABI V-CENTRO SDR6 pipe is an advanced solution designed for the construction of water supply, heating and industrial installations. Made of polypropylene (PP-R) with a centrally located aluminum layer, it combines the advantages of plastic and metallic materials, ensuring high durability and reliability. This is particularly important in central heating systems, where dimensional stability and temperature resistance are crucial.

Construction and properties

The V-CENTRO pipe is characterized by a unique construction – the aluminum layer located centrally inside the polypropylene acts as an anti-diffusion barrier. This eliminates the risk of corrosion of metal elements of the installation (e.g., heating boilers) and prevents air from entering the system. Therefore, the pipe is ideal for use in installations with various heat sources, including condensing boilers. Additionally, the lack of the need to remove aluminum before welding significantly speeds up and simplifies installation.

Application and benefits

VESBO STABI V-CENTRO SDR6 pipe with a diameter of 50mm x 8.3mm is used in:

• Central heating installations: high resistance to pressure and temperature guarantees safe and efficient system operation.
• Hot and cold domestic water installations: physiological inertness of the material ensures no impact on the quality of drinking water.
• Industrial installations: chemical resistance enables the transport of various media.
• Underfloor heating systems: thanks to its low linear expansion, it minimizes stress in the system.

It is worth noting that V-CENTRO pipes are characterized by lower thermal expansion than traditional PP-R pipes, which translates into lower stress in the installation during temperature changes. This in turn affects the longer lifespan of the system and reduces the risk of failure. In addition, the smooth inner surface of the pipe minimizes flow resistance, which translates into energy savings.

Compatibility and standards

VESBO STABI V-CENTRO pipe meets industry standards, guaranteeing its safety and reliability. It is compatible with PP-R welded fittings and threaded fittings with brass inserts equipped with O-ring seals – eliminating the risk of leaks at metal-plastic connections. The standardized dimension ratio (SDR) is 6, and the device pressure class is PN 20 – confirming its resistance to high working pressure.
