Working Process of the Spiral Welded Pipe Mill:(coil car) → (uncoil) → (aligning) → (5 roll leveling) → (aligning) → (shearing and cross welding) → (aligning) → (milling) → (aligning) → milling→ (aligning) → (steel plate cleaning) → (driving) → (pre-bending) → forming → (inside welding) → (outside welding) → (cut to length) → (output distributing) → (on-line UT testing) → (welding flux disposing) → (X-ray testing) → (end-facing) → (hydro-static testing) → (collecting&storage)
