How is polyethylene pipe joined?How is polyethylene pipe joined?The most widely used method for joining individual lengths of polyethylene pipe is by heat fusion of the pipe butt ends as illustrated in Figure 5.1. This technique, which precludes the need for specially modified pipe ends or couplings, produces a permanent, economical and flow-efficient connection.PE Pipe Joining Procedures How to make a polyethylene joint?How to make a polyethylene joint?Polyethylene Joining Procedures 5 - 4 The six steps involved in making a butt fusion joint are 1. Securely fasten the components to be joined 2. Face the pipe ends 3. Align the pipe profile 4. Melt the pipe interfaces 5. Join the two profiles together 6. Hold under pressure Figure 5.2 Typical Butt Fusion Machine for Smaller Diameter Pipe PE Pipe Joining Procedures Joining of polyethylene pressure pipes for below ground pe pipe jointing in iran

What is PE pipe?What is PE pipe?PE pipe can be assembled into a pipeline network by means of fusion or mechanical assembly techniques. Fusion of PE pipe and fittings may be by either Butt Fusion or Electrofusion. Other techniques are available (socket fusion and induction fusion) but are not commonly available and will not be considered here.Methods of joining polyethylene and PE100 pipes
