STAINLESS STEEL EFW PIPES

Stainless Steel EFW Pipes

Stainless Steel EFW (Electric Fusion Welded) Pipes are produced by forming steel plates or coils into cylindrical shapes and joining them longitudinally through electric fusion welding. This method ensures high-quality welded joints and consistent wall thickness throughout the pipe length.

EFW pipes are widely used in high-pressure, high-temperature, and critical industrial applications where mechanical strength, leak-proof performance, and corrosion resistance are essential.
