1.2-3.75mm High Frequency Welded Tube Mill Equipment

1. Product Description:

MA 76 High-frequency Welding Pipe Mill spiral pipe welding machine pre-slit carbon steel CR, HR coils

2. Introduction:

This MA 76 High-frequency Welding Pipe Mill is specially produce high frequency straight seam welded pipes for structural pipe and industrial pipe with Φ32mm~Φ89mm and wall thickness of 1.2~3.75mm. 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.
