ERW – The Market Growth Engine Driven by Efficiency and Cost
Against the backdrop of continuous global infrastructure development and the gradual shift in the energy mix towards natural gas and hydrogen, the Welded Steel Pipe Market is undergoing structural transformation. Among the pipe types, ERW (Electric Resistance Welded) Pipe is emerging as the most dynamic growth area, thanks to its superior production efficiency, precise dimensional control, and significant cost advantages. This market outlook analyzes the key trends and growth drivers for ERW Pipes in 2025, detailing how they continue to expand their market share in low-to-medium pressure applications, solidifying their status as the "King of Efficiency."
Part I: Technology and Manufacturing Trends: Continuous Optimization of ERW
The growth of the ERW pipe market is fundamentally based on the continuous maturation of its manufacturing technology and optimization of production costs.
1.1 Technological Advancements and Cost Competitiveness
Modern ERW production lines are advancing towards higher frequencies and faster speeds, which improves weld quality while reducing energy consumption.
-
Weld Quality Improvement: The adoption of Ultra-High Frequency Welding (UHFW) and Post-Weld Heat Treatment (PWHT) processes can more effectively eliminate residual stresses and defects in the weld zone, making ERW pipe more competitive in medium-level API 5L standards.
-
Raw Material Cost Control: ERW pipe uses steel coil as its raw material. Compared to the steel plates used for LSAW or the billets for seamless pipe, the procurement and utilization costs of steel coil are lower, creating a significant cost barrier in large-scale production.

1.2 Expansion of Size Range
With technological progress, the size range of ERW pipe is expanding towards larger diameters and thicker walls. While still not reaching the limits of SSAW or LSAW, this expansion allows ERW to cover a wider range of municipal and industrial applications. Particularly in the medium-bore market of DN200 to DN600 (approximately 8 to 24 inches), ERW pipe is gradually displacing some seamless and SSAW pipe segments due to its precision advantage.
Part II: Key Drivers of Market Growth
The growth of ERW pipe is primarily fueled by global infrastructure renewal and energy transition demands.
2.1 Infrastructure Renewal Demand
Extensive urban infrastructure renewal is underway across many developed and developing economies in North America, Europe, and Asia.
-
Water and Distribution Networks: The replacement and expansion of urban water supply, drainage, and irrigation systems require large volumes of high-precision, moderately priced pipe. ERW pipe perfectly fits standards like ASTM A53 and A135, making it the preferred choice for municipal pipe networks (Water Pipe).
-
Structural and Building: The use of ERW pipe in structural frames, scaffolding, and small bridges continues to see stable growth, benefiting from its excellent geometric accuracy.

2.2 Energy Transition and Hydrogen Pipeline Potential
-
Natural Gas Distribution: As a transitional fuel, natural gas has huge demand for urban distribution and lateral line construction. ERW pipe, due to its high weld quality and low cost, is the ideal choice for low-to-medium pressure natural gas transport (Gas Pipe).
-
Hydrogen Application Potential: The high strength, low CE, and excellent weld flatness of ERW pipe give it significant technical potential for future low-pressure hydrogen pipeline transport.
Part III: Competitive Advantages and Market Challenges
Despite the optimistic outlook, ERW pipe faces competition from SSAW and seamless pipe, as well as challenges related to technical standards.
3.1 Competitive Advantage: Total Cost of Ownership
ERW pipe boasts significant advantages in Total Cost of Ownership (TCO): lower initial procurement costs, precise dimensional tolerances (reducing field installation and welding complexity), and the ability to deliver quickly, collectively lowering overall project expenses.

3.2 Market Challenges and Standard Limitations
-
Competition from Seamless Pipe: Seamless pipe still dominates small-bore, high-pressure, or high-temperature applications due to its weld-free advantage.
-
Standard Restrictions: ERW pipe remains restricted in major global high-pressure oil and gas trunk lines (such as API 5L PSL2), with its market share concentrated in low-risk and medium-to-low pressure sectors. ERW manufacturers must continuously invest in R\&D to further improve the fracture toughness of the weld seam, aiming to expand into the medium-to-high pressure market.
Conclusion
Looking ahead to 2025, the ERW pipe market is set for continued strong growth, primarily driven by the replacement of aging urban infrastructure and the construction demands of natural gas and new energy distribution networks. Leveraging its unparalleled cost-effectiveness, production efficiency, and continuously improving weld quality, ERW pipe will further solidify its core position in low-to-medium pressure fluid transport and structural applications. Successful ERW manufacturers will be those suppliers who consistently invest in high-frequency welding technology, enhance product dimensional accuracy, and commit to meeting increasingly stringent API/ASTM standards.
