EFW (Electric Fusion Welded) Pipes are produced by electrically fusing high-quality plates or coils, resulting in a strong weld and smooth internal finish. These pipes are designed for large-diameter and high-strength applications, offering excellent dimensional accuracy and mechanical reliability.
Widely used in industries such as oil & gas, petrochemical, power generation, and water transmission, EFW pipes are known for their durability, corrosion resistance, and cost-effective fabrication. They can handle both high-temperature and mildly corrosive environments, making them suitable for critical service conditions.
Available in stainless steel, carbon steel, and alloy steel, these pipes are manufactured in compliance with ASTM/ASME standards. Each pipe undergoes rigorous testing, including NDT and hydrostatic tests, ensuring long service life and dependable performance in demanding applications.
