PPR pipe SDR6 PN20 - 75x12.5 rod 4 m 1229206045

Polypropylene pipe for water and heating installations

Pipe made of polypropylene (PP) with a diameter of 75 mm and a wall thickness of 12.5 mm, supplied in rods with a length of 4 meters. Designed for the construction of cold water, hot water and central heating installations. It is characterized by high pressure resistance - up to 20 bar - which ensures safe use. It is an ideal solution for both professional installers and end users looking for a reliable and durable material for building heating and water systems.

Features and application

PPR SDR6 PN20 pipe is a universal product that, thanks to its properties, finds wide application in various types of installations. Made of polypropylene random copolymer (PP-R), it is resistant to corrosion, high temperatures and mechanical impact. It can be used in cold water installations (up to 20 bar), hot water (up to 10 bar) and central heating (up to 6 bar). Thanks to the smooth inner surface of the pipe, flow losses are minimized, which translates into energy efficiency of the system. Installation is carried out by polyfusion welding, which guarantees tightness and durability of connections.

This pipe is particularly recommended for:

• Internal installations in residential and commercial buildings
• Underfloor heating systems
• Domestic water installations in buildings
• Systems for transporting aggressive media (after consulting with the manufacturer)
• Modernization of existing installations

Advantages and benefits

• Pressure resistance: PN20 pressure class guarantees safe operation even in demanding conditions.
• Chemical resistance: Polypropylene is resistant to the action of most chemicals present in water and heating media.
• Low thermal conductivity: Limits heat loss in heating systems, increasing their efficiency.
• Smooth inner surface: Reduces flow resistance, reducing energy consumption required to pump liquids.
• Easy installation: Polyfusion welding is quick, simple and provides durable connections without the risk of leaks.
• Long service life: The material is characterized by high durability, which translates into a long service life of the installation.
• Compliance with standards: The product meets the requirements of PN-EN 15874 standard, which confirms its high quality and safety. It has CSTB, ITB, Lloyds and PZH certificates, which further increases confidence in the product.

The outer diameter of the pipe is 75 mm, and the wall thickness is 12.5 mm. The maximum working pressure is 20 bar, and the material is polypropylene (PP). The length of the rod is 4 meters. The pipe does not have thermal insulation - additional thermal protection should be considered in installations exposed to low temperatures or large heat losses. The linear thermal expansion coefficient is 0.15 mm/mxK and the thermal conductivity λ - 0.24 W/mxK - these parameters should be taken into account when designing the installation to compensate for thermal movements of the pipes. The minimum bending radius is Rmin - 8.0 Dz mm and the inner wall roughness k - 0.007mm, which affects the efficiency of medium flow inside the pipe.
