PP-R pipe VESBO PN16 40mmx5.5mm /4m/ 1640-4_

PP-R pipe for water and heating installations

VESBO PN16 polypropylene (PP-R) pipe, with a diameter of 40 mm and a wall thickness of 5.5 mm, is a reliable solution for building water supply and heating installations. It is characterized by high resistance to temperature and pressure, which guarantees long-lasting and safe use. The gray color of the pipe makes it easy to identify in the system.

VESBO PP-R pipes are manufactured in accordance with EN ISO 15874-2, which confirms their high quality and compliance with European standards. Regular testing of the outer diameter, wall thickness and ovality ensures dimensional accuracy and product stability.

Features and application

VESBO PN16 pipe is intended for the transport of hot and cold water and heating media in central heating systems. Thanks to the linear expansion coefficient of 0.15 mm/(m.K), the pipe compensates for temperature changes, minimizing the risk of damage caused by thermal stresses. The pipe's peripheral rigidity class ensures its mechanical stability, and the standardized dimension ratio (SDR) of 7.4 guarantees an optimal ratio of inner diameter to wall thickness.

• Strength: Pressure class PN16 means the pipe can withstand a working pressure of up to 16 bar, making it ideal for most domestic and industrial installations.
• Chemical resistance: Polypropylene is a material resistant to corrosion and the action of many chemicals, which ensures the longevity of the installation.
• Easy installation: PP-R pipes are connected by welding, which provides tight and durable connections.
• Hygiene: The material does not affect the quality of the water transported, is neutral to health and the environment.
• Versatility: Can be used in hot and cold water and central heating installations.

Construction and parameters

The pipe is made of polypropylene (PP-R) type 3, which provides it with appropriate flexibility and impact resistance. The nominal diameter of the pipe is DN32, and the wall roughness is 0.007 mm – this affects the reduction of flow resistance of the liquid inside the pipe. Thanks to the precise manufacturing process, the pipe is characterized by a uniform structure and lack of material defects. The pipe does not have a socket or cap – it is a typical straight pipe designed to be connected to fittings by welding.
