What is EFW Pipe
EFW steel pipe, short for Electric Fusion Welded Steel Pipe, is a type of steel pipe manufactured by heating the edges of steel plates to a molten state using high-frequency current, followed by pressing them together with rollers to form a continuous weld.
This production process offers advantages such as high efficiency, energy savings, and environmental friendliness, making it widely used in modern industrial applications.
