Use a welding machine heated to 260°C. Heating times range from 5 seconds (20mm) to 24 seconds (63mm). Test cold water systems at 1.5× working pressure and hot water at 2×. DESO, a manufacturer since 2004, offers a 50-year warranty on its certified PPR systems. PPR pipes have become increasingly popular in plumbing systems due to their exceptional durability and corrosion resistance. You can use these pipes for both hot and cold water applications, with identical techniques across your entire piping network. When installed properly, PPR pipes can last 50+ years without issues. They provide excellent thermal insulation, reduce water flow noise, and resist mineral buildup.

Unlike traditional metal pipes, PPR pipework offers superior corrosion resistance and easier installation, making it ideal for modern construction projects. ## **Preparation** Before beginning any installation, gather these essential tools: - A calibrated PPR welding machine (heated to 260°C) - A quality pipe cutter - Measuring tape - Marker for depth marks - PPR pipes and fittings - Pipe supports and clamps Take time for thorough pipe inspection before you start. Check for manufacturing defects, cracks, or irregularities that could compromise your system’s integrity. Map out your installation route carefully. Consider thermal expansion, support placement, and future maintenance access points. ## **Cutting the Pipe** When you cut the pipe, use a proper PPR cutter for clean, straight cuts perpendicular to the pipe axis. After cutting, examine the ends closely. They should be smooth without burrs or rough edges that could interfere with proper fusion. Clean the cut end thoroughly before proceeding. Even small debris particles can compromise your joint quality. Mark the proper insertion depth on the pipe using the manufacturer’s specifications – typically 14mm for 20mm pipe up to 24mm for 63mm pipe. ## **Heat Fusion Welding** [![standard ppr pipe](https://www.desopipe.com/wp-content/uploads/2025/03/standard-ppr-pipe.webp) ](https://www.desopipe.com/wp-content/uploads/wp-mfa-exports/taxonomy/product_cat/standard-ppr-pipe.md) Make sure your welding machine has reached the correct temperature (260°C) before beginning the fusion process. Insert both the pipe and fitting into the heating tool simultaneously to ensure even heating. Hold everything steady without twisting. Heating times vary by pipe diameter: - 20mm pipe: 5 seconds - 25mm pipe: 7 seconds - 32mm pipe: 8 seconds - 40mm pipe: 12 seconds - 50mm pipe: 18 seconds - 63mm pipe: 24 seconds When heating is complete, quickly remove both components and immediately join them to your marked depth. Hold firmly for a few seconds without adjusting the alignment. This initial cooling phase is when the molecular bond forms. Allow the joint to cool completely before applying any pressure – this takes 2-10 minutes depending on pipe size. ## **Connection Options** While heat fusion creates the strongest pipe connection in plumbing with PPR, some specialized situations might call for mechanical joining methods. Push to connect pipe fittings are occasionally used for temporary connections or in tight spaces where welding equipment can’t reach easily.

Check local building codes, but typically place supports every 60-80cm for horizontal runs. Add extra support near joints, directional changes, and valves where stress concentrations occur. For vertical runs, ensure adequate support to handle the weight of water-filled pipes, which adds significant load to the system.

Apply the appropriate test pressure based on your application: - Cold water systems: 1.5× working pressure (minimum 1.0MPa) - Hot water systems: 2× working pressure (minimum 1.5MPa) Maintain this pressure for at least 30 minutes while checking all joints and connections for leaks. Document your test results carefully. This verifies you’ve completed quality work that meets code requirements and protects you professionally. ## **Critical Installation Considerations** [![deso group certifications](https://www.desopipe.com/wp-content/uploads/2025/05/deso-group-certifications-1.webp) ](https://www.desopipe.com/wp-content/uploads/wp-mfa-exports/page/certificate.md) When working with PPR piping systems, keep these important factors in mind: ### **Temperature Sensitivity** Be careful when installing PPR in cold conditions. These pipes become brittle below 5°C and can crack if handled roughly. ### **UV Protection** For outdoor installations, protect pipes from sunlight exposure. Either use dedicated coverings or specify UV-resistant PPR pipes. ### **Thermal Expansion** PPR expands significantly with temperature changes (approximately 0.15mm per meter per degree Celsius). For long straight runs, incorporate expansion loops or compensators. ### **Material Transitions** When connecting PPR to different materials like copper or steel, use transition fittings with brass threaded inserts to ensure reliable connections. ### **Alignment Issues** Never force misaligned connections. If components don’t align properly, fix the underlying issue rather than forcing the connection. ### **Pressure Ratings** For hot water applications, especially in commercial settings, select higher pressure-rated pipes (PN20 or PN25) for better long-term performance. ### **Documentation** Mark concealed pipe locations on your project documentation. This helps prevent future damage during renovations or repairs. ## **DESO Group: Your Leading PPR Manufacturer** [![](https://www.desopipe.com/wp-content/uploads/2025/04/deso-factory-1-1200x691.webp) ](https://www.desopipe.com/wp-content/uploads/wp-mfa-exports/page/about-us.md) At [DESO](https://www.desopipe.com/wp-content/uploads/wp-mfa-exports/page/home.md), we’ve been manufacturing premium-quality PPR piping systems since 2004.
