PP-R pipe VESBO PN20 40mmx6.7mm /4m/ 2040-4_

PP-R pipe VESBO PN20 with a diameter of 40 mm and a wall thickness of 6.7 mm is an element of water supply and heating installation systems, characterized by high strength and corrosion resistance. Made of polypropylene copolymer (PP-R), it is designed for transporting hot and cold water and heating media in internal installations.

Construction and properties

The VESBO PN20 pipe from the SDR 6 series has an outer diameter of 40 mm and a pressure class of PN20, which means it can withstand a working pressure of up to 20 bar. The linear expansion coefficient is 0.15 mm/(m.K), which should be taken into account when designing installations, especially those with a large length. Wall roughness at 0.007 mm ensures minimal flow resistance, affecting the energy efficiency of the system. The gray color makes it easier to identify the pipe during installation and operation.

Application and installation

PP-R VESBO pipes are widely used in residential, commercial and industrial construction. They are perfect for central heating installations, underfloor heating, and domestic water distribution systems. PP-R pipe installation is done using a socket fusion welder, which ensures durable and tight connections. It is important to properly prepare the surface before welding – the pipe and fitting must be clean and degreased. Thanks to its flexibility (although this model is not flexible), PP-R pipes make it easier to run installations in difficult conditions.

Why choose a PP-R VESBO PN20 pipe?

• Durability and reliability: Made of high-quality materials, resistant to corrosion and mechanical damage.
• Safety for health: Material neutral to drinking water, does not affect its taste or smell.
• Easy installation: Socket fusion welding ensures quick and tight connections, minimizing the risk of leaks.
• Energy saving: Low wall roughness reduces flow resistance, lowering the operating costs of the heating or water system.
• Versatility: Can be used in various types of installations – water, heating and underfloor heating.
• Thermal resistance: Designed to operate at temperatures up to 50°C (average temperature).
