[0002] Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing pipe is to make the molten metal react with the iron matrix to form an alloy layer, thereby combining the matrix and the coating.

[0003] According to the application number: CN202321333754.X, a new type of composite galvanized pipe includes a first galvanized pipe and a second galvanized pipe, which is the main body of the new type of composite galvanized pipe. A first flange is installed on one end of the surface of the first galvanized pipe, a second flange is fixed on one end of the surface of the second galvanized pipe, an external thread is arranged on one end of the surface of the first galvanized pipe, a groove is arranged inside the first galvanized pipe, a buffer spring is arranged inside the groove, and a buffer head is connected to the front end of the buffer spring and corresponds to the groove. The utility model overcomes the shortcomings of the prior art. By setting the first flange, the second flange, the internal thread and the external thread, the two groups of galvanized pipes are first fixed for the first time under the cooperation of the internal thread and the external thread, so that the first flange reaches the second flange, and then the fixing bolts are inserted into the bolt holes in sequence to complete the second fixation, and the sealing gasket improves the sealing of the connection.

[0004] The galvanized pipe in the above case has poor low temperature resistance, which affects the service life of the galvanized pipe in a low temperature environment. In addition, the internal corrosion resistance of the galvanized pipe is not ideal, which makes it easy to pollute the internal fluid after long-term use. At the same time, the surface rust prevention effect of the galvanized pipe is not ideal, and it is easy to rust after long-term use, which reduces the environmental protection effect. For this reason, we provide a low-temperature resistant and environmentally friendly galvanized pipe. Utility Model Content
