Maruichi Stainless Tube Co. Ltd., Japan’s major manufacturer of stainless steel tubes, has commissioned SMS group to supply a complete production line for the manufacture of extruded stainless steel tubes. SMS group will provide the full range of quality‑defining equipment. This includes the heating systems and the forming tube extrusion press with associated automation technology.
The heating systems to be supplied by SMS are fully electrified and comprise a horizontal preheating system for the billets, an intermediate heating system for precise and flexible heating prior to perforation punching, and a final heating system for precise and flexible heating prior to extrusion. By increasing the extrusion force of the horizontal extrusion press from 20 to 50 meganewtons, Maruichi is expanding the range of possible dimensions for stainless steel pipe production.
The plant will be equipped with a highly automated production system to optimize the manufacturing process. The suite of automation solutions increase productivity, minimize human error, and ensure consistent quality across all production stages.
Construction of the new factory building is scheduled to be completed at the end of 2026. Start-up of production is planned during the 2027 fiscal year.
