High-frequency straight seam welded pipe equipment, categorized by coil material, final pipe diameter and thickness, enables continuous straight seam pipe production via solid state high-frequency induction welder. Features include compact structure (small-diameter), strong raw material adaptability (medium-diameter), and new technology design (large-diameter). Advantages: high production efficiency, excellent weld quality, high automation, and energy conservation. Raw coil material, pipe diameter/wall thickness range, welder frequency, production speed, and motor/welding power, determining production capacity and quality. Widely used in construction, petroleum, and municipal engineering.
