TYPICAL PROCESS FLOW
A complete production sequence
Uncoiling → strip joining → accumulation → FFX breakdown forming → fin-pass forming → HF welding → sizing → straightening → cut-off
Final process flow and equipment scope are confirmed after the product range and quality requirements are reviewed.TECHNICAL FAQ
Common buyer questions
What is the main benefit of FFX forming?
It reduces the number of breakdown rolls required across a designed diameter range and can shorten changeover and adjustment time.
Does FFX eliminate every roll change?
No. Breakdown rolls can be common, while fin-pass and sizing sections still require a configuration matched to the finished tube.
