TYPICAL PROCESS FLOW
A complete production sequence
Uncoiling → strip joining → accumulation → forming → HF welding → scarfing → weld inspection → cooling → sizing → straightening → flying cut-off → packing
Final process flow and equipment scope are confirmed after the product range and quality requirements are reviewed.TECHNICAL FAQ
Common buyer questions
Why is thin-wall large-diameter tube difficult to form?
The strip has greater springback and is more prone to ovality, local buckling, wrinkling and weld-seam displacement.
Is the Ø273 × 4.5 mm range fixed?
No. It is a representative delivered project; the new line is engineered for the buyer’s required range.
