salt in the name given to the metals that react in water, so if there is salt in water and it goes through a metal pipe for example, if the metal reacts with water it is going to casue rust.
Fe2O3 does not equal NaCl
I'm guessing rust isn't a salt
Yes, salt and water together provide a easier means for the oxygen in the air to react with the iron.
Sodium chloride is dissociated in water in Na+ and Cl-; the chloride ion has a strong corrosive effect.
YES
Oh yes!
Aluminum is not generally galvanized as the zinc would not be readily sacrificial for aluminum. There are steel products which derive rust resistance from a coating of aluminum and zinc alloy. Properly maintained, they will be rust free for 20 years or longer.
Galvanizing is a process of coating sheet steel with zinc. It makes the steel rust resistant, thereby prolonging it's life. That's why the galvanized roof lasts longer.
the wool does not rust
Pennies are made of copper and don't rust unless they are the zinc pennies issued in 1942 and 1943. However, zinc will not rust either. The so-called steel pennies minted during World War II were made of steel and coated with zinc. If the penny becomes damaged or if the zinc coating is compromised, the underlying steel will rust if exposed to the proper elements. Pennies do corrode though.
Check pipe size for hot water or if galvanized pipe used, pipe could be clogged inside with rust and scale.
Stainless Steel and PoolsEventually, yes, stainless steel will rust if left in a pool. *Yes - bleach will cause stainless steel to rust and chlorine is found in pools. Ergo, pool water will cause rust on stainless steel items.
There's really no such thing as a steel wire fence without galvanising. An ungalvanized steel wire fence would rust the first time it rained. Therefore you'd rather have galvanized steel or another option. Yes, galvanized steel wire is better suited for fences instead of non-galvanized steel wire. The reason for this is that the galvanizationn process coats the steel with a zinc coating, making it rust-resistant in the presence of moisture.
Because they are are galvanized or made of stainless steel
In galvanized steel, a thin coating of zinc is used to protect it from rust or corrosion.
iron (steel) for example if its not galvanized
Yes.
yes old galv pipe will flake and the iron will start to rust causing rusty water.
Answer These are different descriptions for a part. Tubular Steel describes the shape. Steel can be ordered in different sizes and shapes and material properties. Tubular Steel is one type of shape and the process for making the tube will cause the properties for that steel to be slightly different. Galvanized Steel describes a type of finish that protects the steel from corrosion. This process alters the surface of the steel that keeps it protected and thus can be used for construction where it is exposed to the elements. I'm sure you can order a steel tube that has a galvanized finish. Many chain-link fences are made from galvanized steel, including the round posts. Custermen
Galvanized steel has coatings that make it corrosion proof, and with a zink coating, it won't rust. Galvanized steel is seldom used for flooring as it would seem to conduct electrical current, not something really desireable when working with electrified kitchen appliances. Galvanized steel is normally used for water pipes, girders in buildings, etc. Stainless Steel is more common in kitches, especially commercial restaurants. As a flooring material, it would be impractible.

Vegetable oil does not cause rust. It is slightly acidic, its similar to a lubricant and it can prevent rust.
