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.
3. Work process:
Uncoiling→ Accumulating→ Leveling→ Forming→ HF welding→ Deburring
(outer) → Cooling→ Sizing→ Straightening→ Cutting→ Discharging
