What is galvanized steel pipe?
In order to improve the corrosion resistance of steel pipes, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized steel pipe and electric galvanized steel pipe, The hot-dip galvanizing layer is thick, the cost of electro-galvanizing is low, and the surface is not very smooth.
Galvanized steel pipe is a new type of pipe developed by the developed countries in the world in 60 and 70’s, which is forbidden successively after that. Galvanized steel pipes welded with hot dip or electrogalvanized coating on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong the service life.
Galvanized steel pipe has the following production steps:
Black parts inspection → hanging material → degreasing → rinsing → pickling → cleaning → dipping plating aid → hot air drying → hot dip galvanized → cooling → passivation and rinsing → unloading → inspection, dressing → packaging warehousing and transportation.
Galvanized steel pipes application:
Hot dip galvanized steel pipe uses is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube, etc.
Cold galvanization technology is no longer recommend for pipe products. Because of the thin zinc layer, cold galvanized steel pipe has been gradually banned as water pipe and gas pipe in the world. But because of the smooth surface of cold galvanizing process, it is often used to manufacture small parts that need precise plating. Such as screws, machinery manufacturing, electronics, precision instruments, chemical industry, light industry, transportation, weapons, aerospace, atomic energy, etc., are of great significance in the national economy.
What are the advantages of galvanized steel pipes?
- Hot dip galvanizing steel pipe and other aspects of the art of life aesthetics, life is the main mechanism of the coating thickness in a specific environment, and the thickness of the coating depends on the thickness and decision of the galvanized pipe, so the thicker galvanized pipe is easier to coating. Two, in terms of aesthetics and art, in a certain corrosive environment, and then paint the galvanized layer to deal with, as long as the right paint system is chosen, the anti-corrosion effect will be easy to construct.
- After being galvanized, these metal pipes can be used for several different purposes such as: water pipes, gas pipes, chemical piping, sanitary piping, HVAC piping, and industrial piping. They are commonly used in building construction and the development of water systems since they’re extremely durable and last longer than other types of piping such as PVC (polyvinyl chloride) or copper piping.
- Despite the zinc coating, galvanized steel pipe still corrodes faster than copper and PVC pipe. It can’t be used for gas lines because the zinc clogs the line when it begins to flake. Flaking zinc can also cause a galvanized steel water pipe to burst. This material also contains lead, which can taint drinking water. The zinc added to galvanized steel pipe makes it more expensive than regular black steel pipe.
- Galvanized steel pipes, which were used for decades, are made of steel with a coating of zinc, inside and out, to keep the steel from rusting. But over the decades, minerals in water gradually eat away the zinc, and the coating itself wears down from the friction of passing water. Wherever the zinc wears through, rust can form and build up. Rust takes up more space than steel, so the corrosion eventually fills up the pipe.
