There are many ways to classify steel pipes, but the most common method is based on their characteristics. Then we have 04 popular steel pipe classifications: carbon steel pipe, stainless steel pipe, black steel pipe, and galvanized steel pipe.
Carbon steel pipe
Carbon steel pipe is made of steel with carbon as the main chemical element and determines the degree of physical properties such as strength and toughness of the metal, so carbon steel pipe is considered to be the most cost-effective type of steel pipe. During the manufacturing process, producers add carbon to the iron to harden and strengthen the resulting metal.
According to the application, carbon steel pipe is divided into ultra-high carbon steel pipe, high carbon steel pipe, medium carbon steel pipe, low carbon steel pipe, and low carbon steel pipe.
Carbon steel pipes are primarily used to transport water and wastewater underground, in industrial operations involving high temperatures…
Stainless steel pipe
Stainless steel pipes are widely known for their considerable corrosion resistance and are in great demand in many countries. Also known as inox steel pipes, they are made of steel containing iron, carbon, and at least 10.5% chromium content, of which chromium is the main element. In stainless steel pipes, there is a passivation layer that helps protect the metal from deterioration caused by the reaction between chromium and oxygen.
Stainless steel pipes are often used in construction, fluid transportation, and other industries, such as the automotive industry, the pharmaceutical industry…
Black steel pipe
Black steel pipe is the most stable structural steel pipe on sale due to its convenience and high stability. Black steel pipe, also known as raw steel pipe or bare steel pipe, is made of steel that is not covered with any coating. The “black” in its name comes from the dark iron oxide coating that forms on its surface during the manufacturing process.
Black steel pipes are also used to transport water and oil and in the construction industry, especially for making fences and scaffolding.
Galvanized steel
Galvanized steel pipes are made of steel coated with several protective layers of molten zinc to prevent rust and corrosion of the pipes. The galvanizing process was invented in the 1950s, and since then galvanized steel pipes have replaced lead-based pipes.
Galvanized steel pipes are mainly used as water conveyance and building materials, and are widely used in automation and general engineering industries, passenger car bodies, railway bogie manufacturing, and many other industries…
