Kurnool, about three hours from Hyderabad on the Solapur–Kurnool–Chennai corridor, is the site of the Orvakal industrial node, planned for bulk drugs, machinery, electrical equipment and EV manufacturing, and of a Mega Food Park at Tangadacha. We manufacture and electropolish SS 316L and 304L pipes and tubes and quote against your drawings from design stage, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Kurnool sits in the Rayalaseema region, on National Highways 44 and 40, with an airport that began operations in 2021 and a rail link to Hyderabad and Bengaluru. Its industrial future centres on the Orvakal node, being developed as a Mega Industrial Hub under the Hyderabad–Bengaluru Industrial Corridor. Industries named for it include bulk drugs, machinery and electrical equipment, and a proposed electric-vehicle park. A Mega Food Park of about 758 acres at Tangadacha in Jupadu Bungalow mandal was launched for fruit, vegetable and spice processing, agri-biotech and research, and a maize-processing unit was announced at Orvakal.
A word on fit. EV assembly, machinery and electrical-equipment plants don't use electropolished pipe on their main processes. Where we're useful is the bulk-drug and pharma plants' purified water and clean utilities, the food-park and agro-processing lines, DM and DI water in the larger plants, and the EPC contractors and fabricators who build all of it.

316L with a smooth internal surface and verified passivation, specified at design stage.
Smooth, passivated 304L and 316L for demineralised-water and clean-utility lines.
A smooth, passivated interior that cleans easily and doesn't hold residue, for plants that wash, blend or heat their product.
A smooth bore cleans faster and drains better.
Cut-to-length pipe with heat-number traceability and a document pack your client's inspector will accept.
Quotes against your drawings and specification, with the document pack you'll need for commissioning.

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.
