1. Product Description:

MA 20 High-frequency Welding Pipe Mill Outer diameter Φ10~25mm Production speed 0～100m/min

2. Introduction:

The MA 20 high-frequency welding pipe mill is used to produce both welded pipes of 10~25mm in diameter and 0.3～1.5mm in wall thickness. Square and rectangular pipes and deformed pipes of the corresponding size are available too. This equipment uses roll pass design, so the production line can produce welded steel pipes which has the feature of good quality machining and precision assembling.

3. Work process:

Uncoiling → Cutting and Welding → Cage accumulator →(Feeding, Forming), (Seam guide, HF welding, Squeezing, Deburring), Water cooling, Sizing, Rough Straightening → STD Flying Saw →Checking and Collecting →packing→Storage
