Wavin PPR pipe WT 50x6.9x4000 PN16 3050537

PP-R pipe for water supply and heating installations

Wavin WT 50x6.9x4000 PN16 pipe is an installation system component made of polypropylene (PP-R) designed for the safe and durable distribution of drinking water and water in central heating systems. It is characterized by high resistance to corrosion and deposits, which guarantees long-term reliability. It is a choice for both professionals and demanding end-users.

Construction and application

The pipe with a nominal diameter of DN 50 and an outer diameter of 50 mm, with a wall thickness of 6.9 mm, is perfect for internal installations in residential, commercial and industrial buildings. Made of high-quality material, this pipe is resistant to high temperatures and pressures (PN 20), allowing it to be used in various applications. The SDR 7.4 dimension ratio provides adequate mechanical strength. The lack of seals eliminates the risk of leaks at connection points.

Advantages and properties

• Durability and reliability: PP-R material provides resistance to corrosion, deposits and the action of chemical substances present in water and heating agents.
• High thermal resistance: The pipe withstands temperatures up to +95°C (short-term), allowing its use in underfloor heating and radiator systems.
• Low thermal conductivity: The thermal conductivity coefficient of 0.24 W/(m.K) minimizes heat loss in the heating system, which translates into energy savings.
• Smooth inner surface: Reduces flow resistance, which affects the efficiency of the installation.
• Easy installation: PP-R pipes are connected by welding, which ensures tight and durable connections without the need for additional sealing elements.
• No impact on water quality: The material is neutral to drinking water and does not contaminate it.
• Coefficient of thermal expansion: 0.15 mm/(m·K) - an important parameter in installation design taking into account temperature changes.
• White pipe color: Facilitates identification in the installation and aesthetic execution.

The pipe length is 4 meters, which makes it easy to adapt to specific installation needs. The inability to bend the pipe requires the use of fittings to change the direction of the installation.
