Pithampur is Madhya Pradesh's largest industrial area, known as the "Detroit of India" for its automotive plants and home to a dedicated pharma zone in the Indore SEZ. We manufacture and electropolish SS 316L and 304L pipes and tubes and supply Pithampur's plants directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Pithampur sits in Dhar district about 30 km from Indore, and its workforce largely commutes from the city. It is the state's largest industrial area, with more than 1,250 industries in operation by one count and around 1,500 by another across Phases I, II and III. The Indore Special Economic Zone, established in 2003, is also here, with a pharma zone in Phase II and Sector III that hosts a large share of the state's export-oriented pharma manufacturing. Alongside pharma, the area is known for several major automobile and auto-component makers, engineering and machinery plants, and an apparel park. An ESDM (electronics) park with common facilities has been proposed in Sector 7, and the state describes a multi-product industrial area of about 469 hectares in Dhar district as one of its fastest-growing.
A word on fit. Auto assembly, machining and apparel don't use electropolished pipe on their main processes. Where we're useful is the pharma zone, clean utilities such as DM and DI water inside the auto and engineering plants, food and beverage units, and the fabricators who serve them.

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.
