Chittoor is India's biggest mango-pulp district, with dozens of pulp units, a Mega Food Park at Mogili and a large tomato and fruit belt around Madanapalle and Piler. We manufacture and electropolish SS 316L and 304L pipes and tubes and supply Chittoor's fruit and food processors and fabricators directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Chittoor lies in the far south of Andhra Pradesh, bordering Tamil Nadu and Karnataka, and it is the state's largest mango-producing district, with around 80,000 hectares of mango and an annual output of roughly 7.5 lakh tonnes, much of it the Totapuri variety grown for pulp. The district hosts around 40 or more mango-pulp processing units with a combined annual capacity of about 4 lakh tonnes, many of them exporting pulp. The Srini Food Park at Mogili in Bangarupalem mandal is a central-government-assisted Mega Food Park listed as operational, with a common multi-fruit processing line of about 10 tonnes an hour for mango, papaya, guava and tomato. Around Madanapalle and Piler, tomato, banana and other fruit feed further processing, including farmer-owned tomato units. The district's industrial profile also lists a fruit-processing cluster, a rice-mill cluster and a granite cluster.
A word on fit. Rice milling and granite are dry processes and don't use electropolished pipe. Where we're useful is the fruit and tomato lines (pulping, heating, filling), CIP, aseptic and hot-fill systems, and the fabricators who build and repair that equipment. The mango-pulp trade has been through a hard patch, so many buyers are repairing or upgrading rather than building new lines.

| Tomato and fruit processing (Madanapalle, Piler and the tomato belt) | Tomato paste, puree, banana and other fruit products | Product transfer, CIP, clean utility | 316L (acidic); 304L for dry-side lines |
| Chittoor town industrial estates, including new estates | MSME manufacturing and fabrication | Skid assemblies, headers, small lots | 304L / 316L, cut to drawing |
| Dairy and beverage units | Milk and drinks | Milk transfer, CIP | 304L; 316L for acidic or salted products |
| Rice mills and granite | Dry processing and stone | Not a fit | n/a |
A smooth, passivated 316L interior that rinses clean and resists acidic pulp, with 304L for wash water and steam.
Smooth, documented tubing for heating, holding and filling lines, specified to your design.
Hygienic tubing that cleans easily and resists acid and salt.
A smooth bore cleans faster and drains better, which matters for caustic and acid wash cycles between seasons.
Cut-to-length pipe with heat-number traceability for the shops that build and repair processing lines.
Quotes against your drawings and shutdown window, so installation fits the gap between seasons.

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.
