Three main forming processes have become established in LSAW tube production. We focus on the JCO process. This method is not only very flexible, it also requires lower investment compared to other methods. Therefore, it has quickly established itself on the market after its development by SMS group.
The process perfectly fits small and medium-sized production capacities and enables flexible production, covering regular up to very challenging pipe dimensions at high quality. But also high capacity plants (500,000+ tpa) can be realized. Thanks to the VSP (Variable Speed Pumps) hydraulic system, the JCO pipe forming press along with the crimping process offer economic and ecologic production with a low carbon footprint.
Customer challenges addressed
- The stepwise forming process allows a wide range of pipe diameters, wall thicknesses, and steel grades to be processed on the same line.
- Incremental forming and precise gap closing create optimal conditions for welding and ensure high roundness and tight tolerances.
- Compared with other large‑diameter pipe processes, JCO requires fewer forming tools and offers an economical plant layout.
- Controlled forming, parallel plate edges, and stable welding preparation result in reliable weld seams and repeatable pipe quality. Systems such as SMS group’s SHAPE technology automatically optimize forming parameters, reducing operator dependency and increasing productivity from the first pipe.
