Amravati is building one of India's largest textile regions, and its MIDC estates also host food and agro-processing units that need clean, easy-to-sanitise pipe. We manufacture and electropolish SS 316L and 304L pipes and tubes and supply Amravati's plants directly, packed for the long haul, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Amravati district has a string of MIDC estates. The main ones are the Amravati MIDC and the Additional Amravati MIDC at Nandgaon Peth, with smaller estates at Achalpur, Anjangaon Surji, Daryapur, Morshi, Warud and elsewhere. Next to the Nandgaon Peth estate, the PM MITRA integrated textile park covers 1,020 acres, about 30 km from the Samruddhi Expressway, and has a common effluent treatment plant. Around the city, the district's farming belt feeds food and agro-processing units. A word on fit: Spinning, weaving and garment-making don't use electropolished pipe. Where we are useful is the water and dosing lines in textile wet-processing units, food and agro plants, and new-build projects that specify clean utilities at design stage.

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.
