PPR pipe SDR6 PN20 - 25x4.2 4 m length 1229206035

Polypropylene pipe for water and heating installations

KAN-therm PP SDR6 PN20 pipe is an element of the installation system made of random polypropylene (PP-R). It is a universal solution designed for the construction of cold and hot water installations and central heating. It is characterized by high resistance to pressure and temperature, which ensures long-lasting and trouble-free operation. Available in the form of a 4-meter long rod, it facilitates installation and minimizes waste.

Construction and application

The pipe is made of polypropylene, which guarantees resistance to corrosion and deposits. The pressure class PN20 means that it can operate at a maximum working pressure of 20 bar. SDR6 (Standard Dimension Ratio) defines the ratio of the outer diameter of the pipe to the thickness of its wall – in this case 6, which affects its stiffness and strength. This makes the pipe perfect for installations exposed to variable operating conditions.

• Polyfusion welding: KAN-therm PP pipes are connected by polyfusion welding, which ensures durable and tight connections.
• Multi-application: Can be used in cold water, hot water and central heating installations.
• Durability: Polypropylene is a material resistant to corrosion and deposits, which extends the life of the installation.
• Safety: The pipes meet the PN‑EN 15874 standard and have CSTB, ITB, Lloyds and PZH certificates, confirming their safety and quality.
• Thermal expansion: The linear thermal expansion coefficient α is 0.15 mm/mxK – an important parameter when designing installations taking into account temperature changes.

The pipe with an outer diameter of 25 mm and a wall thickness of 4.2 mm is ideal for conducting installations with medium flow. Its uniform structure facilitates welding and minimizes the risk of errors during assembly. This allows installers to count on quick and efficient installation without the need for additional tools or mechanical processing of the pipes before welding. The length of the 4 m rod allows for optimal use of material and reducing the number of welded joints – which translates into saving time and labor costs. In addition, quality certificates guarantee compliance with applicable standards and building regulations.
