Carbon steel pipe in the performance of the outstanding performance is high yield strength and stress corrosion resistance, has good weldability, welding cold crack and hot crack are less sensitive.
Carbon steel tubes are divided into hot rolled and cold rolled (drawn) steel tubes.
Hot rolled carbon steel tubes are divided into general steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological tubes and other steel tubes.
Cold rolled (dial) carbon steel pipe generally are divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, also includes carbon thin wall steel pipe, alloy thin wall steel pipe, stainless steel pipe, special-shaped steel pipe.

Q215 is a type of carbon structural steel that complies with the Chinese national standard GB/T 700-2006. The "Q" in its name stands for yield strength, while "215" indicates a minimum yield strength of 215 MPa, which decreases gradually as the thickness of the steel increases. Its chemical composition is primarily low carbon (carbon content ≤0.15%), with sulfur and phosphorus content controlled according to grades A and B. It possesses good plasticity, toughness, and weldability, and is typically used directly in the hot-rolled or normalized state.

Q195 carbon steel pipe is a welded steel pipe made of carbon structural steel. Its yield strength is 195MPa (thickness ≤16mm), tensile strength ranges from 315 to 430MPa, and elongation is ≥32% (thickness or diameter >16mm)

Q345 carbon steel pipe (also known as 16Mn) is a low-alloy high-strength structural steel that complies with the GB/T 1591-2008 standard. It has a high yield strength (≥ 345MPa) and good low-temperature toughness

Q420 carbon steel pipe belongs to low-alloy high-strength structural steel, with a yield strength of 420MPa and a tensile strength range of 520-680MPa. This steel has high strength, good low-temperature toughness, and welding stability, and is widely used in scenarios such as power towers, heavy machinery, and oil rigs. ‌
