Electric Resistance Welded Pipes (ERW / HFI)

ERW/HFI pipes are among the most versatile industrial solutions, offering high strength, precision, and excellent surface quality. Manufactured by cold-forming steel and welding it using high-frequency electric current, these pipes feature a seamless appearance and strong, durable joints—without any filler metals.

Thanks to advanced HFI welding technology, ERW pipes ensure smooth surfaces, tight tolerances, and efficient fabrication. They are ideal for applications requiring high performance and clean aesthetics.

Key Advantages:
No filler metal used – stronger and cleaner weld
Invisible weld seam – ideal for visible or precision applications
Safer and faster production via high-frequency welding

Manufacturing Standards:
EN10217, EN10219, API 5L, ISO3183, ASTM/ASME

Available Sizes:
Diameters: 8 mm – 530 mm Wall Thickness: 0.6 mm – 13 mm Ends: Plain or beveled

Applications:
Oil & gas pipelines, natural gas transport, refineries, petrochemical plants, power stations, water supply, food industry, shipbuilding, automotive and structural works.
