Carbon steel pipe is a type of steel pipe made from carbon steel, which is a combination of iron and carbon. It is known for its strength, durability, and resistance to corrosion. Carbon steel pipes are commonly used in industrial applications such as oil and gas, water transport, and construction. They are also widely used in plumbing and heating systems. Carbon steel pipes come in various sizes and thicknesses to suit different applications.

ASTM 1045 Seamle Steel pipe is a high-quality carbon structural steel tube with a carbon content of 0.42-0.50%, a tensile strength of 610MPa, and a yield point of 360MPa; it is used for general shaft parts.
