Electric Fusion Welded (EFSW) pipes
Electric Fusion Welded (EFSW) pipes fabricated for heavy-duty, large-diameter requirements where standard seamless sizing is not feasible.
When your project scales beyond standard diameters, Electric Fusion Welded (EFSW) pipes deliver the heavy-duty performance required. Fabricated from high-grade stainless steel plates rather than coils, these pipes undergo a robust fusion welding process. EFSW pipes are heavily utilized in large-scale infrastructure, refineries, and petrochemical process industries where large-bore piping is mandatory.

Electric Resistance Welded (ERW) pipes offering exceptional dimensional accuracy and a high-quality longitudinal weld for small to medium diameters.
Our Electric Resistance Welded (ERW) stainless steel pipes are formed from premium steel coils and welded longitudinally. This highly controlled, high-frequency manufacturing process results in superior dimensional tolerances, uniform wall thickness, and a smooth surface finish. ERW pipes are highly cost-effective and ideal for standard pressure environments in the chemical, dairy, and architectural sectors.
