Khammam is a food-and-agro city on the Hyderabad–Vijayawada road, with a Mega Food Park at Buggapadu and a coal, power and paperboard belt in Kothagudem and Bhadrachalam. We manufacture and electropolish SS 304L and 316L pipes and tubes and supply Khammam's food plants, clean-utility lines and contractors directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Khammam city is about 200 km east of Hyderabad on the road to Vijayawada, and the district stretches north-east into forest, coal and river country. Its most relevant project is the Mega Food Park at Buggapadu, developed by the state's industrial infrastructure corporation to provide common infrastructure for food processors. Khammam also has long-standing rice-mill and granite-polishing clusters. In the north-east, Kothagudem and Manuguru have coal mining, Paloncha has iron and steel, ferro-alloy and power plants, and the Bhadrachalam belt has a large paper and pulp mill.
A word on fit. Rice milling, granite polishing, coal, power, sponge iron and ferro-alloys are dry or heavy processes. Where we're useful is wet agro lines in the food park, chilli and spice pastes, clean utilities such as DM water and laboratory lines inside the large plants, and the contractors who maintain 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.
