Step-by-Step Welding Procedure for PPR Pipe Fittings
Pipe and Fitting Preparation
You want to achieve perfect pipe to pipe weld results. Start by preparing the PPR pipes and preparing the PPR fittings with care. Use a sharp pipe cutter to make clean, straight cuts. Remove burrs with a deburring tool. Clean every surface with a lint-free cloth. Make sure you remove oil, rust, paint, moisture, and dirt. These contaminants can weaken the fusion and cause leaks.
Choose a cleaning agent like Weld-On® C-65™ Cleaner to wipe away grease and oil. Always store your pipes and fittings in a dry, cool place away from sunlight. This prevents material degradation and keeps your welding process smooth.
Observação: Surface preparation is often neglected, but it is vital for a strong fused joint. Clean, dry, and smooth surfaces help you avoid weak spots and leaks.
Welding Procedure: Heating and Joining
Follow this step-by-step welding procedure to get strong, leak-free joints:
Mark the insertion depth on the pipe. This helps with the correct positioning of the pipe.
Align the pipe and fitting. Make sure the positioning of the pipe is straight and the fitting is fully seated.
Set your PPR welding machine to the correct temperature. For PPR, heat the components at 260 ° C ± 10 ° C.
Check the table below for the right heating time based on pipe diameter:
Diâmetro da tubulação
Tempo de aquecimento
20mm
5 segundos
63mm
24 segundos
Insert both the pipe and fitting into the heating plate. Heat the components without twisting.
When the time is up, quickly remove both parts. Join the heated components by pushing the pipe into the fitting straight to the mark. Do not twist or push past the mark.
Hold the assembly steady until the pipe to pipe weld sets.
Tip: Avoid twisting during insertion. Twisting can break molecular bonds and create weak joints.
Resfriamento e Inspeção
Let the pipe to pipe weld cool before handling or pressure testing. Use the table below for cooling times:
Diâmetro do tubo (mm) | Cooling Time (minutes) |
|---|---|
Até 25 | 3 - 5 |
32 - 50 | 5 - 10 |
Ao longo 50 | 10 - 20 |
After cooling, inspect the welded joint. Look for a smooth, even surface. The color should be uniform. Check for cracks, bubbles, or burn marks. These signs show poor fusion or overheating. Examine the socket area and internal surfaces for rough edges or voids. A good weld means a strong, leak-free connection.
Callout: Always pressure test the system after welding. This ensures the pipe to pipe weld holds under real conditions.
Solução de problemas e dicas de segurança
If you find leaks or weak spots, follow these steps:
Find the exact leak location. Look for cracks or holes.
Desligue o abastecimento de água.
Cut out the damaged section with a pipe cutter.
Clean the ends of the remaining pipes.
Install new fittings and connectors using your PPR welding machine.
Weld the pipes together again, making sure there are no gaps.
Insulate the joint and check for leaks after turning the water back on.
For small leaks, use a PPR repair clamp or epoxy putty. For larger cracks, wrap a rubber sheet and secure it with hose clamps.
Stay safe during every welding procedure. Wear safety goggles, heat-resistant gloves, and protective clothing. Make sure your workspace has good ventilation. Set the machine temperature correctly and monitor it. Keep first aid supplies nearby. Turn off the machine when not in use.
