Product Description
Types of Carbon Steel Round Tube
According to the manufacturing process, carbon steel round pipes are generally divided into seamless carbon steel pipes and welded carbon steel pipes, and seamless pipes are further divided into Cold Drawn Seamless (CDS), Hydraulic and Hot Finished; welded pipes are further divided into Electric Resistance Welding (ERW ) and Drawn-Over-Mandrel (DOM).

seamless carbon steel pipe

welded carbon steel pipe
According to the carbon content, carbon steel round pipes are divided into low carbon steel pipes, medium carbon steel pipes and high carbon steel pipes. Low carbon steel, also known as mild carbon steel.Â
Carbon steel pipes are divided into two types: hot-rolled and cold-rolled (drawn) steel pipes. Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.

Hot Rolled Steel Tube

Cold Rolled Steel Tube
In addition to general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (dial) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Rust thin-walled steel pipes, special-shaped steel pipes. The outer diameter of hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel pipe can reach 6mm, and the wall thickness can reach 0.25mm. The outer diameter of thin-walled pipe can reach 5mm, and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.

high pressure boiler steel pipe

oil gas seamless steel pipe

low temp steel pipe
Carbon steel welded pipe and tube are used in high-pressure conditions. They are highly resistant to shock and vibration, making them ideal to transport fluids. Carbon steel pipes are widely used in a number of industries, such as transporting water and sewage, oil and gas industries, boiler and condenser tubes, high-pressure applications, and chemical processing.
- Transporting water and sewage
- Oil and gas industries
- Boiler and condenser tubes
- High-pressure applications
- Chemical processing
Additional steel processing services
cutting Service
For parts that require extremely high wear resistance, we use abrasive waterjet cutting to maintain hardness throughout the part without creating a heat-affected zone. For thicker plates up to 200mm, we use precisely controlled CNC oxy-fuel cutting. For products requiring high cut quality and dimensional tolerances, we use high-definition underwater plasma cutting to maximize plate performance in abrasive applications.

Metal in China®(XINTUOYUAN) offers band saw cutting services for structural tubes. Bandsaw cutting is a fast, efficient process that can cut entire bundles of steel pipe at once. It is ideal for cutting large tubes and high volumes. Band saw cutting is a cost-effective method of pipe cutting that can cut through a variety of materials quickly and efficiently. Due to its benefits, it is suitable for various industries.
Metal in China®(XINTUOYUAN) provides welded carbon steel pipe services, including TIG (tungsten inert gas), MIG (metal inert gas) and SMAW (shielded metal arc welding) welding processes. In an industrial environment, MIG provides simple and efficient high-speed welding, while SMAW provides the flexibility to weld in any position. But when high purity and quality are required, there is no more efficient process than TIG.
TIG welding process offers the following benefits:
- Applicable for all types of carbon steel welding
- Reduced hydrogen embrittlement
- Excellent purity with inert gas shielding and back purging
- Precision welding with weld parameter control
- Controlled heat input and cooling for reduced weld defect, especially in high-carbon steel
