Embodiment Construction
[0020] The present invention is a low-carbon steel heating wire PE electrofusion pipe fitting, which comprises a PE pipe fitting and a heating wire compounded on the inner wall of the PE pipe fitting. Surface polishing, multi-layer copper plating anti-corrosion, anti-oxidation treatment and plastic treatment. After plastic treatment, the two parallel heating wires are directly and evenly wound and compounded on the inner wall of the PE pipe fitting.
[0021] The cross-sectional area of the heating wire in the present invention is 0.5-5 square millimeters.
[0022] The step of the overplastic treatment in the present invention is as follows: uniformly wrapping the two parallel heating wires with 2-5 mm thick plastic that is the same as the PE pipe fitting.
[0023] When using the PE electric fusion pipe fitting of the present invention to connect the PE pipe, insert the PE pipe into the PE electric fusion pipe fitting, use the electric fusion pipe welding machine to energize ...
