A Good Practice Guide for the Butt Fusion Jointing of HDPE Pipes

Fusion Procedures for HDPE Pipe Butt Fusion

• 1.Make sure heater plate is at 5000 F. +/- 100 F.
• 2.Use a clean paper towel to clean pipe ends.
• 3.Place pipe in the jaws of the fusion machine and check the high, low alignment. Adjust if necessary. (Make sure the pipe is secured in the jaws to avoid slipping)
• 4.Use the facing tool to square the ends of the pipe.
• 5.Remove any fragments left from facing with a clean utensil( knife, awl, etc.) DO NOT TOUCH THE PIPE WITH YOUR HAND!
• 6.Place the heater plate between the opposing pipe ends and bring the ends into contact with the heater plate. DO NOT APPLY FORCE! (The only force required is to maintain contact between pipe ends and heater face).
• 7.Apply heat for recommended heating time. (DO NOT ATTEMPT TO ESTABLISH THE RECOMMENDED BEAD SIZE DUTING THE HEATING CYCLE).
• 8.Remove the heater face and quickly press the heated pipe ends together. DO NOT SLAM THE ENDS TOGETHER! Apply enough pressure to establish the recommended bead size.
• 9.Continue applying pressure as the joint cools for the recommended cooling time.
• 10.Let the joint cool an additional 3 minutes before removing it from the fusion machine.
• 11.Double check the joint closely to ensure proper roll back and bead size.
• 12.Do not “rough handle” or move the pipe until the joint has cooled to the ambient temperature.
