The tube mills operate on high-frequency induction welding and Laser welding technologies.

The tube mills at Maruichi Kuma are dedicated to stainless steel manufacturing operating on High-Frequency induction welding and Laser welding technologies. It is an edge that speaks volumes of the company’s command in the industry and capability to induce innovative manufacturing practices for optimal product quality.

Quick roll changeover considerably increases the production uptime.

The mill has been specifically designed to roll stainless steel tubes. Quick roll changeover considerably increases the production uptime and contributes positively to the overall capacity. Further, features like, online edge preparation and external & internal bead removal within the mill ensure maximum tube strength and superior quality.


Our weld quality is further ensured by online Eddy Current Tester.

The mill uses variable high-frequency induction welding technology for welding tubes and Laser welding, practices that render great welding strength to the tubes without using any kind of filler material. The weld quality is further ensured by the online Eddy Current Tester for inspection of any possible welding flaws.

The tolerances achieved for the ‘first time’ within the industry.

Precision cutting of the tubes is done using an in-built rotary cut-off system at tolerances that have never been achieved before in the industry. The true-sized tubes are then passed on to the re-cut machine, if required, for cutting of tubes into multiple smaller length tubes as per specifications. Once the desired sizes have been achieved, the cut tubes are subjected to end-finishing techniques like deburring and chamfering, inspected finally, and then moved to the packing section.

  • The finished & approved tubes are bundled and then Suitably Packed to avoid any in-transit damage.
