Electric Resistance Welded steel pipes are an innovation in the steel pipe manufacturing industry. Known for their durability and precision, they are made by rolling metal and welding it longitudinally across its length.

Their superior quality, cost-effectiveness, and efficiency make them a preferred choice in many industrial and construction projects. In this article, we will explore the characteristics, manufacturing process, and applications of ERW steel pipes. Read on to learn more.

What are ERW Steel Pipes?

These pipes are made through a pressure welding process known as electric resistance welding. For this process, two rolls of uncoiled steel sheets are fused without a welding filler or metal. The rolls are combined by heating the edges of the steel pipe with a high-frequency electric current and applying constant force to form a bond.

They are known for their mechanical strength, higher production efficiency, lower cost, and easy automation. Moreover, they exhibit exceptional strength and can withstand extreme temperatures, pressures, and other external factors.

What are the Main Applications of ERW Pipes?

ERW pipes are used for low to medium-pressure applications, making them ideal for several industries.

Oil and Gas Industry

The industry uses ERW pipes for transporting oil, gas, and petroleum products due to their high durability and resistance to corrosion. These pipes are often present in oil and gas extraction sites. Their manufacturing process makes them ideal for transferring oil and gas products over long distances.

Additionally, their resistance to corrosion makes them last longer, enabling oil and gas companies to reduce maintenance costs. This resistance makes them an essential part of the industry’s piping systems, as they can handle the corrosive elements present, which might otherwise damage the pipelines if not properly managed.

Water Supply and Irrigation

Water supply systems favor ERW wipes, especially in those handling and transporting water and other potentially corrosive elements. The smooth interior of the pipes also helps in managing water flow, running smoothly, and minimizing friction and pressure drops.

These pipes are lightweight and easy to handle and install, reducing labor costs. Their standardized fittings facilitate quick, secure connections and streamline repairs. These features are valued in irrigation systems since they can withstand harsh field conditions such as soil and water.

Furthermore, their ease of installation and standardized fittings simplify the setup and modification of irrigation systems, making them a reliable choice for efficient water distribution.

Construction Industry

ERW steel pipes are favored in the construction industry as structural support in buildings, bridges, and other infrastructure projects. Their high strength allows them to withstand heavy loads, making them ideal for use in columns, beams, and trusses on construction sites.

In addition to structural support, these steel pipes are commonly used in fencing and scaffolding due to their durability and ease of assembly. They provide reliable barriers and stable platforms for construction activities.

On top of that, they are used in cladding and roofing applications, where their smooth surface finish and resistance to corrosion guarantee durability and visual attractiveness.

Power Plants

Power plants, both thermal and nuclear, use ERW pipes to transport coolant fluids, such as water or steam within the plant. Their ability to withstand high temperatures and pressures makes them well-suited for this type of operation.

In nuclear plants, these pipes are used as casing or containment for fuel rods, serving as a barrier. Additionally, their strength and corrosion resistance makes them crucial for transporting radioactive fuel materials.

On the other hand, these pipes are used in thermal power plants to cool systems and steam lines. Their sturdy design facilitates the effective movement of hot fluids and steam, which is essential for producing energy and preserving operational stability.
