What are the differences between galvanized steel pipes and stainless - steel pipes?

Stainless - steel welded pipes and galvanized steel pipes are increasingly used in our daily lives. So, what are the differences between the two?

Galvanized steel pipe is a new - type pipe with good corrosion - resistance. Compared with ordinary steel pipes, its outer layer is plated with a layer of zinc. This layer of zinc forms a very good protective film on the outer layer of the pipe, which can effectively delay the rust and corrosion of the steel pipe. Stainless - steel welded pipe, also simply called welded pipe, is a steel pipe made of common steel or steel strip after being rolled and formed by a machine set and dies.

1. Different application ranges

Stainless - steel welded pipes are mainly used in the fields of petroleum, chemical industry, medicine, and food. In addition, when the bending and torsional strength are the same, they are lighter in weight, so they are also used to manufacture mechanical parts and engineering structural parts. They can also be used in the fields of decoration and furniture. Galvanized steel pipes are welded pipes with a hot - dip galvanized or electro - galvanized surface. They are mainly used in the manufacturing industries of construction, machinery, coal mines, chemical industry, electric power, railway vehicles, automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery.

2. Different concepts

Galvanized steel pipe is a steel plate with a layer of metal zinc coated on its outer layer. It can prevent the outer layer of the steel plate from being corroded and prolong its service life. General steel pipes and other plates treated by galvanization are called galvanized steel pipes. Stainless steel is a kind of steel that can resist the weak corrosion of air, water vapor, steam, and the chemical corrosion of acids, alkalis, and salts.

3. Different processing technologies

The surface of galvanized steel pipes is plated with a layer of zinc, which plays a good anti - corrosion role and prolongs the service life of the steel pipes. Stainless steel is steel with other metal elements added to its interior, and the internal structure changes to make the product rust - resistant.

Therefore, there are still great differences between stainless - steel pipes and galvanized steel pipes. We can choose the materials we need according to the actual application situation.
