The Jiangsu 4220 ultra-large-caliber flat-head chamfering machine is operating smoothly.
10 Feb,2026
This 4,220-square-meter edge-beveling machine has now entered a stable operational phase. The equipment runs smoothly, with consistent cycle times and excellent processing consistency. The machine features a dual-head configuration, enabling simultaneous machining of both ends of a single steel pipe. It is controlled by a PLC, offering advantages such as reduced labor intensity for operators and easy operation. Its precise edge-beveling process effectively removes burrs and sharp edges from the pipe ends, ensuring smooth progress in subsequent processing steps while reducing safety risks and enhancing product safety. The flat-end edge-beveling machine adopts a single-station, dual-head layout, with the steel pipes precisely positioned at their center, allowing simultaneous edge-beveling at both ends.
Device parameters:
Steel pipe diameter: Φ820–Φ4220 mm
Steel pipe wall thickness: 6–28 mm
Steel pipe length: 6–13 m
Steel pipe material: Q235; Q355
As an important finishing step at the backend of the spiral welded pipe production line, chamfering the pipe ends directly determines the quality of the pipe end faces and the efficiency of subsequent butt welding.
From the perspective of on-site processing results:
✅ Flat end face, uniform cutting
✅ Standard chamfer angle, clean and neat shaping.
✅ The entire machine operates stably and features a high degree of automation.
✅ Suitable for processing large-diameter, thick-walled steel pipes.
