Product Description

High Precision Straight Seam ERW Round Square Tube Steel Pipe Welding Making Machine


Summary of Pipe Welding Machine

This high-frequency welding pipe mill is specialized equipment to produce high frequency straight seam welded pipes for structural pipe and industrial pipe with Φ20mm~Φ76mm and wall thickness of 1.0~2.5mm. Through optimization design, best materials choice, and accurately fabrication and rolls, the whole line can be reached high precision and high speed. Within suitable range of pipe diameter and wall thickness, pipe production speed can be adjusted.
