Product Knowledge

Proper installation of HDPE 45-degree elbow butt fusion fittings is essential to ensure a strong, leak-free connection in your piping system. Butt fusion is a common method used to join HDPE pipes and fittings by melting the ends and fusing them together. Here are the general steps for installing an HDPE 45-degree elbow butt fusion fitting:
Clamp or Fixture Setup:Use clamps or fixtures to hold the pipes and the fitting in place. This ensures that they remain aligned during the fusion process.
Heating Plate Setup:Set the heating plate on the butt fusion machine to the appropriate temperature based on the manufacturer's recommendations and the pipe diameter.
Heating the Pipes and Fitting:Place the heating plate between the ends of the pipes and fitting, ensuring even contact.
Allow the pipes and fitting to heat for the duration specified by the manufacturer. The heating time depends on the pipe diameter and material thickness.
Remove Heating Plate:Carefully remove the heating plate from between the pipes and fitting.
Joining the Pipes and Fitting:Quickly remove the pipes and fitting from the clamps and immediately join them while the HDPE material is still in a molten state.
Align the Pipes:Align the pipes and fitting accurately, ensuring that the ends make full contact and form a straight line.
Fusion and Cooling:Hold the pipes and fitting in place for the fusion process to complete. The HDPE material will gradually solidify as it cools.
Cooling Time:Allow sufficient time for the fused joint to cool and solidify completely. Follow the manufacturer's recommendations for cooling time.
Trimming the Bead (Optional):If your fitting leaves a bead of melted material at the fusion joint, you may need to trim it using a bead trimmer to achieve a smooth surface.
Quality Inspection:Inspect the fusion joint for any irregularities, gaps, or signs of incomplete fusion. The joint should be smooth and even.
Pressure Testing:Consider conducting a pressure test to ensure the integrity of the joint and the overall system.
