PP-R Pipe Elbow 32/45 mm, Detal-met Kolano nyplowe KN4532

Detal-met Kolano nyplowe KN4532 is a PP-R pipe elbow designed to connect pipes with nominal diameters of 32 mm and 45 mm at a right angle. Made from polypropylene random copolymer (PP‑R), this fitting is corrosion-resistant, chemically stable and suitable for concealed and exposed installations in water supply and heating systems. The elbow enables a secure transition between two different pipe sizes while maintaining flow integrity and minimizing pressure loss.

Advantages

The PP-R material offers long service life and resistance to scale, chemical corrosion and biological growth. Lightweight design simplifies handling and installation compared with metal alternatives. The socket connections provide reliable, leak-resistant joints when fused with appropriate welding tools. The fitting’s smooth internal surface reduces flow resistance and supports consistent water delivery in plumbing and heating circuits.

Suitable for

• Domestic and commercial hot and cold water distribution
• Central heating circuits and radiator connections
• Systems requiring a transition between 32 mm and 45 mm PP-R pipes
• Corrosion-prone environments where non-metallic fittings are preferred

Key specifications

• Material: polypropylene random copolymer (PP‑R)
• Connection type: socket for fusion welding
• Nominal diameters: 32 mm and 45 mm
• Angle: 90° elbow
• Color: typically white or light-colored PP-R (may vary by production batch)

How to use

Before installation, verify compatibility with existing pipe dimensions and system pressure ratings. Cut pipe ends squarely, deburr and clean the surfaces to be joined. Use an appropriate PP-R welding tool to heat the socket and pipe ends according to the tool manufacturer’s temperature and time settings, then insert the pipe into the elbow socket and hold until the joint cools. Ensure the assembly is aligned at 90° and allow joints to cool fully before pressurizing the system. Follow local plumbing codes and manufacturer recommendations for installation and testing.

Usage recommendations

Use suitable PP-R welding equipment and follow safety instructions. Avoid exposing the fitting to direct flame or solvents. For hot water and heating applications, confirm the operating temperature and pressure limits of the entire system before use and perform pressure testing after installation.
