Key Takeaways

What is Carbon steel tubing

Carbon steel tubing is a type of metal tube manufactured from carbon steel, a steel alloy with iron and carbon, primarily for use in industrial applications. It is known for its superior corrosion resistance, making it ideal for use in applications where it is exposed to extreme temperatures and other elements.

Welding techniques for carbon steel tubing involve high-frequency electric resistance welding to ensure strong and reliable joints. It also has a high thermal conductivity, meaning it is well-suited for applications requiring the transfer of heat.

Carbon steel tubing is available in a range of surface finishes, from polished and annealed to hot rolled or cold rolled, depending on the application. It is also highly impact resistant, making it ideal for use in applications where it may be subject to vibration or shock.

The corrosion resistance, welding techniques, thermal conductivity, surface finish options, and impact resistance of carbon steel tubing make it a popular choice for a variety of applications.

Moving on, we will now discuss electric resistance welding.

Electric Resistance Welding

Continuing from the previous discussion on carbon steel tubing, electric resistance welding (ERW) is a popular manufacturing process for creating round, cylindrical shapes from metal coils. It involves welding through electrical resistance, which is an automated process with a low manufacturing cost. ERW offers high weld quality and strong joins, making it suitable for use in the automotive industry for axels, chassis, supports, stands, and internal machine components. It is also cost-effective and versatile, making it an ideal choice for many applications.

Comparing ERW to other welding techniques used in carbon steel tubing, such as cold drawn seamless (CDS) or drawn-over-mandrel (DOM), ERW offers a lower cost but with less accuracy in terms of tolerances and wall thickness. Quality control is important when it comes to ERW and other welding techniques used in carbon steel tubing, as it is essential to ensure the tubing meets specific standards.

In recent years, advancements in carbon steel tubing manufacturing have made it possible to produce high-quality tubing with improved strength, hardness, and machinability. This makes it easier to produce complex shapes and structures, which can be used in various industries and applications. The cost effectiveness of ERW tubes make them an attractive option for many projects.

Cold Drawn Seamless (CDS)

How does CDS compare to electric resistance welding for carbon steel tubing production? Cold Drawn Seamless (CDS) is a method of piercing hot metal billets to create a tube shape, rolling to elongate and reduce diameter, and achieving tight tolerances for accurate dimensions. The wall dimension is thicker for strength, which makes CDS suitable for roll cages, shafts, and hydraulic cylinders, among other applications. Compared to ERW, CDS provides a tighter tolerance, thicker walls for strength, and an excellent aesthetic for finished products. It is also used in infrastructure projects and precision sensitive applications. Carbon steel tube manufacturers offer a variety of advantages, including a bright and clean finish with chemically controlled material, improved strength, hardness, and machinability, and cost-effective options.

Drawn-Over-Mandrel (DOM)

Using a Drawn-Over-Mandrel (DOM) process, metal coil is cut to required width and cold rolled into a tube shape before being welded together using electric resistance under pressure.

This carbon steel tube manufacturing process provides a number of advantages over other techniques, such as Cold Drawn Seamless (CDS); improved strength, hardness and machinability, thinner walls, and tighter tolerances.

The hydraulic tubing produced through DOM is also preferred for its bright and clean finish with chemically controlled material, making it ideal for applications where fluid is pumped or bending/flaring is important.

ERW tubing is another popular carbon steel tube, widely used in the automotive industry for axels, chassis, supports, stands, and internal machine components.

The properties and composition of carbon steel tubes provide the perfect balance of strength, durability, and cost-effectiveness. This makes them ideal for use in infrastructure and construction projects, machinery and tools, and even ornamental designs.

With this in mind, it is easy to see why hydraulic tubing is becoming increasingly popular.


Building on the advantages of DOM, hydraulic tubing is a popular carbon steel tube widely used for applications where fluid is pumped or bending/flaring is important. The manufacturing process involves welding flat rolled metal or rolling and piecing bar stock, followed by controlled finishing stages for hydraulic standards. The result of this process is a bright and clean finish with chemically controlled material that is ideal for hydraulic lines and bending/flaring.

Compared to other types of carbon steel tubing, hydraulic tubing is characterized by its high strength and shock resistance, along with its ability to withstand violent weather conditions. It is also cost-effective and environmentally friendly, making it a great choice for a variety of applications.
