Kuma draws its strength and garners the trust of its customers through a meticulously planned manufacturing setup.

Capable of producing 24, 000 metric tons of high frequency induction welded steel tubing annually; its production unit operates on the latest in tubing technology.

The tube mill at Kuma is the only mill in India Dedicate to stainless steel operating on High Frequency induction welding technology. An edge that speaks volumes of the company’s command in the industry and capability to induce innovative manufacturing practices for optimal product quality.

The mill has been specifically installed to roll stainless steel tubes and commands a speed of 70 mtrs/minutes. Quick roll changeover considerably reduces the production time and contributes positively to the overall capacity. Further, features like, on-line edge preparation and external & internal bead removal within the mill ensure maximum tube strength and superior quality.

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

Precision cutting of the tubes is done using an in-built rotary cut off system at tolerances that have never been achieved 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 draped in shrink packing material to avoid any in-transit damage.
