Sanand and the estates around it are where Ahmedabad's newer industry sits, with pharma, electronics, engineering and the state's automobile cluster. We manufacture and electropolish SS 316L and 304L pipes and tubes and supply Sanand's plants directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Sanand is a large GIDC industrial estate about 30 km from Ahmedabad, on the highway towards Saurashtra and Kutch. Its first two phases, Sanand I and Sanand II (Bol), host pharma, textile, food and engineering plants. Sanand III at Khoraj is the Japan Industrial Township, a newer estate for electronics, pharma and engineering, and the state's automobile cluster is centred here. Along the Sarkhej–Bavla highway, the Changodar estate is a younger pharma and engineering belt, with Bavla and Dholka further south adding more pharma and manufacturing units. GIDC describes Sanand as a zero-discharge estate. A word on fit: Automobile and electronics plants use electropolished pipe mainly on clean utilities such as DM water, not on the main plant piping. Our strongest match here is pharma, plus new-build plants that specify clean utilities at design stage.

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.
