PP reducing coupling 90/50 306-90/50-V

Pipe diameter reduction in PP-R installations

The PP reducer fitting 90/50 is an element of heating and water installation systems made of polypropylene (PP-R). It is used to connect pipes of different diameters – in this case, it reduces the diameter from 90 mm to 50 mm. It is designed for welding, which ensures a durable and tight connection.

Features and application

This fitting is crucial when changing the pipe diameter, e.g., when connecting devices with a smaller opening to the main installation pipeline. It allows for a smooth transition between different dimensions, minimizing pressure loss and ensuring optimal medium flow. Made of high-quality polypropylene, it is resistant to corrosion and high temperatures, guaranteeing long-term use.

• Durable connection: The welding method creates an inseparable connection, eliminating the risk of leaks.
• Chemical resistance: Polypropylene is resistant to most chemicals present in heating and water installations.
• Versatility: Suitable for use in both central heating and domestic hot and cold water installations.
• Easy installation: Welding requires specialized equipment, but the process is relatively quick and easy for an experienced installer.
• Safety: The use of high-quality materials ensures safe use for a long time.

Construction and installation

The PP reducer fitting 90/50 is characterized by precise workmanship, which facilitates its welding with PP-R pipes. Before welding, ensure that the surfaces of the pipes and fitting are clean and degreased. The welding process should be carried out in accordance with the manufacturer's recommendations for welding equipment to obtain optimal connection strength. Remember to use the appropriate heating time and clamping force – too short a time may result in insufficient bonding, and too long a time – damage to the material.
