PPR pipe SDR7.4 PN16 - 90x12.3 length 4 m 1229203016

Polypropylene pipe for water and heating installations

KAN-therm PP-R SDR7.4 PN16 pipe with a diameter of 90 mm and a wall thickness of 12.3 mm, supplied in 4-meter lengths, is a reliable solution for building water and heating installations. Made of random polypropylene (PP-R), it is characterized by high strength and corrosion resistance, guaranteeing long-term use. It is a homogeneous pipe, meaning it has the same structure throughout its thickness – this ensures stability and safety of connections.

Application and product features

The pipe is intended for cold water (up to 16 bar), hot water (up to 10 bar) and central heating (up to 6 bar) installations. Thanks to the pressure class PN16 and SDR7.4 coefficient, it works perfectly in systems with increased requirements. The gray color of the pipe makes it easy to identify in the installation. Additionally, the material is characterized by a low linear thermal expansion coefficient (0.15 mm/mxK) and thermal conductivity (0.24 W/mxK), which minimizes heat loss in the heating system. The minimum bending radius is 8D – this allows for flexible routing of the installation without the risk of damaging the pipe.

• Strength and durability: Made of high-quality random polypropylene (PP-R) resistant to corrosion and high temperatures.
• Versatility: Designed for cold water, hot water and central heating installations.
• Safety: Pressure class PN16 guarantees safe operation of the system.
• Easy installation: Connection by polyfusion welding allows for tight and durable connections.
• Long warranty: The manufacturer offers a 10-year warranty (up to 15 years in individual construction).
• Compliance with standards: The product meets the requirements of PN‑EN 15874.

Construction and parameters

The pipe has a smooth inner wall with a roughness of k = 0.007 mm, which minimizes flow resistance and ensures efficient operation of the installation. Thanks to the homogeneous material structure, the pipe is resistant to cracking and mechanical damage. The weight of a 4m length is approximately 2.87 kg and the dimensions are 90 x 90 x 4000 mm. High product availability (over 1640 m) ensures continuity of installation work.
