High precision machine unit for stainless steel welded pipe

This machine unit is specially used for producing round (Square and rectangle pipe≤2.5mm )stainless steel straight seam welded pipes. It made by refined materials in high precision and equipped with fixed length fly saw. It is composed of main machine includes uncoiler, leveler, forming, welding ,sizing and straightening device. The machine is equipped with solid and rigid structure, and adopts humanized design with features of easy and safe to operate.The rolling speed can be adjusted according to the pipe diameter and wall thickness.

The work process as follow for reference:

Raw material (steel coil)→uncoiling → shearing and end welding→non-power leveling→mill-forming→TIG welding and plasma welding→Polishing burrs outside of weld seam →→ cooling → sizing → roughly straightening → fixed length cutting → finished pipe →run-out table
