[0002] Galvanized steel pipes are welded steel pipes with hot-dip or electroplated zinc layers on their surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as pipelines for general low-pressure fluids such as water, gas, and oil, they are also used as cable laying casings.

[0003] In the prior art, such as the Chinese patent: CN212480395U's "A new type of composite galvanized pipe", includes a galvanized pipe body, an inner lining plastic pipe, an end flange and a plug, the inner lining plastic pipe is attached to the inner wall of the galvanized pipe body; the end flange includes a vertically connected inner pipe pressure edge and a flange end face, the inner pipe pressure edge is annular, the inner pipe pressure edge presses the inner lining plastic pipe, and the two flange end faces extend out of the galvanized pipe body and are connected to the ends of the two adjacent galvanized pipe bodies by a bolt and nut assembly; a plug hole is provided on the flange end face, the plug hole extends in an axial direction parallel to the galvanized pipe body, the plug is tightly plugged in the plug hole, the plug is an arc-shaped structure, and the inner wall of the plug fits the outer wall of the galvanized pipe body.

[0004] However, in actual use, the above patented galvanized pipe has the following defects: poor electrical insulation performance. Since its steel material has a certain conductivity, when the cable is damaged and leakage occurs during long-term use, the current is easily conducted quickly through the galvanized pipe, which can easily cause a certain risk of electric shock and cause certain damage to equipment along the way. For this reason, we propose an environmentally friendly galvanized pipe with good electrical insulation. Utility Model Content
