Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel pipes, in particular to a corrosion-resistant galvanized steel pipe. Background Art

[0002] Galvanized steel pipe is a kind of steel that is coated with a layer of zinc on the surface of the steel pipe to enhance its corrosion resistance. Galvanizing can be done by hot-dip galvanizing or electro-galvanizing. Hot-dip galvanizing is to immerse the steel pipe in molten zinc liquid to form a zinc layer, while electro-galvanizing is to generate a zinc layer on the surface of the steel pipe through an electrochemical method.

[0003] Common galvanized steel pipes generally need to be connected when used. When connecting, the galvanized steel pipes need to be cut according to the required length, and then connected with pipe clamps.

[0004] However, when the galvanized steel pipe is cut, the coating on the surface of the galvanized steel pipe will also be cut, and the internal material of the cut surface of the galvanized steel pipe will be exposed. During long-term use, the exposed part will come into contact with moisture, causing the cut surface of the galvanized steel pipe to be easily corroded. At the same time, the galvanized steel pipe needs to be fixed by a pipe clamp when connected. When the pipe clamp is clamped, the coating on the surface of the galvanized steel pipe will rub against the pipe clamp, and the coating will be worn due to the friction. When the pipe clamp is replaced later, the worn part of the galvanized steel pipe surface will be exposed, causing the connection of the galvanized steel pipe to be easily corroded. Utility Model Content

[0005] 1. Technical issues to be solved

When the pipe clamp is subsequently replaced, the worn part on the surface of the galvanized steel pipe will be exposed, causing the connection of the galvanized steel pipe to be easily corroded.
