Jajpur district is home to the Kalinganagar–Duburi industrial cluster, one of India's densest steel and ferro-alloy zones, with a stainless-steel mill, rubber works and Odisha's chromite belt around it. We manufacture and electropolish SS 304L and 316L pipes and tubes and supply the clean-utility, DM-water, sampling and laboratory lines of these plants, and the contractors who maintain them, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Jajpur district lies in north-eastern Odisha on the Howrah–Chennai rail line, with Jajpur Road as its main rail junction. Its industry is concentrated in the Kalinganagar Industrial Complex, which spans Jakhapura, Dangadi and Duburi and is described as one of India's most concentrated steel manufacturing zones. Large integrated steel plants and a stainless-steel mill operate there, with ferro-alloy and rubber works alongside, and the pollution-control board's records list a string of iron-and-steel units at Kalinganagar, several of which are noted as not in operation. The district also holds Odisha's chromite deposits. The state's industrial infrastructure corporation developed the Kalinganagar complex, and Jajpur is within easy reach of Cuttack, Bhubaneswar and Paradeep.
A word on fit. Steel-making, ferro-alloy smelting, chromite mining and rubber processing are heavy, dry or abrasive processes whose main lines use carbon steel and specialty alloy. The district also makes stainless steel itself, so local buyers have easy access to ordinary stainless in other forms. Where we're useful is the small set of clean lines inside the plants (DM water, boiler-feed, sampling, instrument and laboratory lines), finished electropolished tube for fabricators who need a measured Ra and documents, and the contractors who maintain the plants.

Oils, cutting fluids and drawing residues are completely removed first. The finish is only as good as the chemical preparation.
Where weld heat tint or surface oxide is present, it is etched and activated so the pipe surface electropolishes uniformly.
The pipe acts as anode in an electrolytic acid bath. High microscopic peaks dissolve first, levelling the surface and stripping free iron.
The chromium-rich passive layer is stabilised per ASTM A967 / ASTM B912 to prevent future pitting and galvanic attack.
High-purity deionised water rinse removes all electrolytic residues, followed by hot air drying, capping and clean poly-sleeving.
