Carbon steel pipe is a type of steel pipe that is made of carbon and iron, with a varying amount of carbon depending on the grade. Carbon steel pipes are commonly used in a variety of industrial applications, such as oil and gas drilling, transportation of water and chemicals, and structural applications. They are also used in the construction of buildings, bridges, and other structures due to their strength and durability. Carbon steel pipes can be classified into several grades based on their carbon content, with higher carbon content generally indicating greater strength and hardness. These pipes can also be distinguished by their surface finish, which can be either black or galvanized. Overall, carbon steel pipes are a versatile and reliable option for a wide range of applications.
