Four engineering decisions that define the line
Roll forming, HF welding, sizing and cut-off are designed, built and tested as one system. No integration gaps, no split responsibility.
TC rolls · quick cassettes
Dual-radius pass schedule, cantilever / shaft design, fast size changeover without full strip-out.
100–600 kW · contact or induction
Solid-state oscillator with automatic impedance control and bead scarfing for minimal flash.
6 stands · online seam option
Multi-stand sizing for tight OD tolerance and consistent shape; online seam annealing available.
Flying cut · ±1.5 mm
Continuous flying cut-off with auto chamfering option and precise length repeatability.
The five-stage process — one continuous line
Coil in, finished tube out. Every stage is engineered to minimize flash, scrap and changeover time.
Hydraulic mandrel
Strip accumulator & edge guide for continuous, damage-free feed.
Breakdown & fin pass
TC rolls, dual-radius pass, quick cassette change.
Contact / induction
100–600 kW, automatic impedance control, bead scarfing.
Multi-stand sizing
OD ±0.1 mm, wall ±5%, online seam annealing option.
Flying cut
±1.5 mm length, auto chamfering optional.
