Wavin PPR pipe WT 25x4.2x4000 PN20 3050499

Polypropylene pipe for water supply and heating installations

Wavin PPR pipe with a diameter of 25 mm and a wall thickness of 4.2 mm is a reliable solution for building water supply, heating and sanitary installations. Made of polypropylene (PPR), it is characterized by high resistance to temperature, pressure and corrosion, which guarantees long-lasting and trouble-free operation. The length of the rod – 4 meters – makes it easy to adapt to the needs of a specific project and minimizes the number of connections.

The pipe is designed for transporting both cold and hot water, and can also be used in central heating installations (observing the manufacturer's recommendations). Thanks to its properties, it is ideal for use in residential, industrial and commercial construction. A standardized dimension ratio (SDR) of 6 ensures adequate mechanical strength.

Characteristics and application

Wavin PPR pipes are produced from polypropylene type 3 (PPR), which ensures their high quality and durability. They are resistant to chemicals, making them an ideal choice for a variety of applications. The possibility of using them in underfloor heating and radiator systems (depending on the application class) increases their versatility. Pressure class PN20 means that the pipe is adapted to work at a working pressure of up to 20 bar.

It is worth paying attention to the classification of applications: class 1 for cold water (20°C), class 2 for hot water (70°C), class 4 for underfloor heating and low-temperature radiators, and class 5 for high-temperature radiators. Choosing the appropriate application class is crucial to ensure optimal performance and safety of the installation. The coefficient of thermal expansion at 0.15 mm/(m·K) should be taken into account when designing the installation to avoid thermal stresses.

Product advantages and installation

• Durability: PPR material ensures a service life of the installation reaching up to 50 years.
• Safety: The pipes are harmless to health and do not corrode, which affects the quality of drinking water.
• Easy installation: Quick and clean installation using standard welding methods.
• Low noise: They provide quiet operation of the installation due to low pressure losses caused by friction.
• Ecology: The possibility of recycling the material contributes to environmental protection.
• Chemical resistance: Allows the transport of various liquids and gases (after individual assessment).

The installation of Wavin PPR pipes requires the use of specialized welding tools, which ensures tight and durable connections. Follow the manufacturer's installation instructions and take into account the operating conditions of the installation (pressure, temperature).
