Vadodara is an engineering, machinery, chemical and pharma city on the Ahmedabad–Mumbai corridor. We manufacture and electropolish SS 316L and 304L pipes and tubes and supply Vadodara's plants directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Vadodara's industry is spread across the city and the estates around it. The Makarpura GIDC estate, set up in 1970, is the city's oldest, with engineering, machinery and auto-component units. Nandesari, to the north-east, is a chemical and pharma estate. To the east and north, the Waghodia, Por–Ramangamdi and Savli estates are larger and newer, and Halol, across the district border in Panchmahal, adds engineering, automotive and chemical plants. Savli and Halol together form a Special Investment Region. West of the city, the Koyali–Padra belt holds the refinery and its fertiliser, alkali and petrochemical neighbours. A word on fit: Plants have been moving out of the older city estates towards Waghodia, Savli, Por and Halol, so check where your customers are now. Refinery and petrochemical main process piping is mostly carbon or alloy steel. Where we're useful is the clean side: purified water, utilities, laboratory lines, food lines and the equipment builders who make machinery for these plants.

Instant dimension calculation and Ra unit conversions for engineering procurement
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.
