80m/min 0.8-3.0mm High Frequency Welding Tube Mill

1. Product Description:

MA 50 High-frequency Welding Pipe Mill Tube Thickness Min 0.8 Max 3.0mm carbon steel, cold rolled, hot rolled pre-sli​

2. Introduction:

This MA 50 High-frequency Welding Pipe Mill is specialized equipment to produce high frequency straight seam welded pipes for structural pipe and industrial pipe with Φ20mm~Φ63mm and wall thickness of 0.8~3mm. 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.
