PPR pipe SDR6 PN20 - 40x6.7 mm, 4 m length 1229206039

Polypropylene pipe for hot and cold domestic water and central heating

PPR SDR6 PN20 pipe is an installation system component made of random polypropylene (PP), designed for safe and durable distribution of domestic water – both cold and hot – and in central heating systems. It is characterized by high resistance to corrosion and deposits, ensuring long-term reliability. Widely used in residential and commercial construction.

Features and application

The pipe with an outer diameter of 40 mm and a wall thickness of 6.7 mm, supplied in 4-meter lengths, is ideal for creating extensive installations. It withstands working pressure up to 20 bar, making it suitable for most standard water and heating systems. The PN 20 pressure class guarantees safe use. Thanks to its structure, the pipe is easy to process and install, and connections are made by polyfusion welding – this method ensures the tightness and durability of connections.

This pipe is used in:

• cold water installations
• hot water installations
• central heating installations
• underfloor heating systems
• industrial installations (in accordance with permissible parameters)

Product advantages and standards

By choosing this PPR pipe, you gain not only a reliable installation component, but also a product that meets high quality standards. It complies with the PN-EN 15874 standard, confirming its safety and suitability for use. It also has CSTB, ITB, Lloyds, PZH and ZiK certificates – demonstrating compliance with the stringent requirements of various research institutions. The uniform structure of the pipe minimizes the risk of cracking and ensures the longevity of the installation. The white color makes it easier to identify the pipe during installation and operation. The linear thermal expansion coefficient is 0.15 mm/mxK and the thermal conductivity λ - 0.24 W/mxK, which affects the stability of the installation with temperature changes. The minimum bending radius Rmin is 8 D mm and the internal wall roughness k - 0.007mm ensure optimal medium flow.
