Ratlam is a railway and agro-processing town in western Madhya Pradesh, famous for its namkeen and sev, with a purpose-built snack cluster and a planned investment region around it. We manufacture and electropolish SS 304L and 316L pipes and tubes and supply Ratlam's food plants, oil and soya processors and fabricators directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Ratlam sits on the Mumbai–Delhi rail line and the road to Jhabua, about 140 km from Indore. Its best-known industry is namkeen, and the state developed a dedicated Namkeen Cluster and Allied Food Industries area at Karmadi, about 3 km from the city on the Ratlam–Jhabua highway, with 124 plots and about ₹22.75 crore approved under the central micro and small enterprises cluster programme (reported in 2017). The district grows soybean, wheat, jowar, gram and maize, and soya and oilseed processing is a natural extension. The district has six industrial areas listed in the district industrial profile. Ratlam is also part of the planned Ratlam–Nagda Investment Region, a node of the Delhi–Mumbai Industrial Corridor identified for engineering, auto components, pharma, apparel, gems and jewellery and herbal industries.
A word on fit. Gems and jewellery, apparel and most grain processing are dry. Where we're useful is the oil, wash and utility lines of snack and food plants, edible-oil and soya processing on the clean side, and design-stage projects in the investment region.

| Gems, jewellery and apparel | Jewellery and garments | Mostly dry; not a fit | n/a |
A smooth, passivated interior that cleans easily and doesn't hold oil or spice residue, for plants that fry, blend or wash their product.
Hygienic tubing for hot-oil and refined-oil lines, once we've checked the temperature and cleaning chemistry.
Smooth, passivated 304L for wash, boiler-feed and clean-utility lines.
A smooth bore cleans faster and drains better, which matters for caustic and acid wash cycles.
Cut-to-length pipe with heat-number traceability for the shops that build fryer-line and process equipment.
Quotes against your drawings and specification 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.
