Product Specification of HDPE – Pressure Piping System      Electrofusion  fitting  (EF)  is  a  pipe-joining  element  including  electrical
                                                                resistance coils inside. Electrofusion welding machine applies automatically

    Polyethylene pressure piping system is a highly corrosion resistant pipe   After pipe ends that will be joined are inserted in EF fitting, energy is applied
    system, which is able to transfer axial forces, which results in only a limited   by the EF welding machine to the EF fitting through the resistance coils
    need for anchoring. PE pipes are manufactured from different kinds of PE   which causes the material to melt and leading to fusion of the pipe and the
    materials. One of the most commonly used PE resin designations in world   socket.
    is PE 100.

    VESBO PE-100 pipes are produced in two different colors, black and blue.
    Black pipes are additionally marked with a blue line.       Butt Fusion

                                                                This joining method is usually preferred for the big (>63mm) diameter pipes.
                                                                The principle of butt fusion is to heat surfaces of the two pieces to a
