Carbon steel pipes are divided into hot rolled and cold rolled (pulled) steel pipes.

Hot rolled carbon steel pipeis divided into ordinary steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipe, etc.

Cold rolled (dialed) carbon steel pipeis divided into ordinary 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, but also includes carbon thin-walled steel pipe, alloy thin-walled steel pipe

Carbon Steel Seamless Pipes– it contains more carbon and iron in its composition. Depending on the grade, trace amounts of silicon, manganese, and copper are permitted in varying quantities. Therefore, the Carbon Steel Seamless Pipe material is stronger and is extremely resistant to stress. In heavy-duty facilities, these features make the pipes applicable.

Carbon Steel Welded Pipes– are used in high-pressure conditions. In a range of industries, such as the transport of water and waste, the oil and gas industries, high-pressure applications, and chemical manufacturing, carbon steel pipes are commonly used.

Carbon Steel ERW Pipes– have various features like Lightweight, Corrosion resistance, structured appropriately, Precision engineered, intricate detailing, Economical, and more. These ERW pipes are used in Ship Building, Automobile, Boilers & Pressure Vessels, Railways, Oil & Petro Chemicals, Coal & Mining, Transmission Towers, and General & Heavy Engineering.

Carbon Steel LSAW Pipes– has some fine features such as easy installation, seamless finish, Rustproof, and more. As these LSAW pipes are expensive, they are not widely used in lower value non-energy applications such as water pipelines.
