Hot-dip galvanized steel pipe is also called galvanized steel pipe. The reason why it is called galvanized steel pipe is that it has undergone special treatment, such as galvanizing process. Galvanizing means galvanizing on the outer or inner wall of the steel pipe to improve the anti-corrosion effect. Its service life, at present, most of the cold galvanized steel pipes in my country are used in industry, and only hot-dip galvanized steel pipes are still used in cities. Then the service life of galvanized steel pipe is what we are most concerned about. The following editor will introduce to you how long the steel pipe after galvanizing process can be used.
Hot-dip galvanized steel pipes have a long service life, and galvanizing can increase the corrosion resistance of steel pipes and prolong service life. Galvanized steel pipes for urban use can reach 30 years, and galvanized steel pipes used in other corrosion-prone areas have longer lifespans, and how long they can be used is mainly due to the thickness of the galvanized layer of the steel pipes.
After the steel pipe is galvanized, it has actually played a role in preventing rust, and no other anti-rust treatment is required. If you want to further improve the anti-rust effect, you can use the method of physical anti-rust, that is, brush a layer of anti-rust paint or spray a layer of anti-rust paint on the surface.
Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensers in chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, and pipes for trestle piles, supporting frames for mine tunnels, etc.
The anti-corrosion period of galvanizing is long, but the anti-corrosion period is different in different environments: 13 years in heavy industrial areas, 50 years in oceans, 104 years in suburban areas, and 30 years in cities. Galvanizing has essentially played a role in rust prevention, and no other rust prevention treatment is required. If you want to further improve the anti-rust effect of galvanized steel pipe, you can use the method of physical anti-rust, that is, use anti-rust paint to treat the surface.
How long is the service life of hot-dip galvanized steel pipe? The content is here. At present, my country has completely banned the use of cold-galvanized steel pipe. , Be sure to understand whether you need hot-dip galvanized steel pipe or cold-galvanized steel pipe.
