Abstract

The invention discloses a metal pipe and a production method of same. A main body of the metal pipe includes, by weight, 4.5-6 parts of Cu, 1.5-2.5 parts of Mn, 1.5-2.5 parts of Ti, 90-95 parts of Al and 5-10 parts of Zn. The inner side wall of the main body of the metal pipe is coated with an anticorrosion coating which includes, by weight, 10-30 parts of bisphenol A-epoxy chloropropane type epoxy resin, 40-60 parts of N-methyl pyrrolidone, 5-10 parts of butanone, 5-10 parts of a pigment, 20-40 parts of zinc phosphomolybdate, 20-40 parts of zinc oxide, 50 parts of ethyl acetate, 40 parts of a polyurethane adhesive, 60 parts of graphite powder, 10-20 parts of epoxypropane butyl ether, and 20-30 parts of polyaniline. The main body of the metal pipe is free of being swelled, dissolved, damaged and decomposed by a corrosive medium.

Description

technical field [0001] The invention relates to a pipeline, in particular to a metal pipeline and a preparation method thereof. Background technique [0002] Corrosion is one of the main causes of damage and failure of metal pipelines. There are two main types of environments that cause corrosion of metal materials: one is the natural environment, such as the natural atmosphere, ocean, soil and other weak corrosion environments; the other is the industrial environment, such as highly corrosive industrial gases and industrial solutions. In the corrosion of natural environment, the corrosion type belongs to electrochemical corrosion and biochemical corrosion, the effect is weak, the corrosion speed is slow, the short-term corrosion damage is small, but the potential damage is relatively large; and if it is used for highly corrosive industrial gases, When used in solution environment and sewage discharge, the corrosion type belongs to chemical corrosion and biochemical corrosi...
