Comparison and Applications of Stainless Steel, Carbon Steel, and Galvanized Steel Pipes

Pipes are essential materials in industry, construction, and machinery. The three common types are:

Stainless steel pipes: Corrosion-resistant, high-temperature resistant, and aesthetically pleasing.

Carbon steel pipes: High strength and cost-effective, suitable for pressure and structural applications.

Galvanized steel pipes: Zinc-coated surface for rust protection, ideal for outdoor or humid environments.

This article compares the three types from material, performance, processing, and application perspectives.
