Ramagundam is Telangana's power and fertiliser town, with a super thermal power station, coal mining at Godavarikhani and cement plants around it. We manufacture and electropolish SS 304L and 316L pipes and tubes and supply the clean-utility, DM-water, sampling and laboratory lines of these plants, and the contractors who serve them, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Ramagundam is in Peddapalli district, on the Godavari, about 210 km north-east of Hyderabad on the Hyderabad–Ramagundam highway and the north–south railway line. Its industry is heavy and public-sector led: NTPC's Ramagundam Super Thermal Power Station is one of the major power stations in South India; Singareni's coal operations run through Godavarikhani; and fertiliser, cement and agro mills are located across Peddapalli district.
A word on fit. Power, coal, fertiliser and cement plants run mostly on carbon steel and specialty alloys, and their main process piping isn't electropolished. Where we're useful is the small set of clean lines inside those plants: DM water, boiler-chemistry and water-analysis sampling lines, instrument and laboratory lines, and food and utility lines in the town. We also supply the fabricators and contractors who maintain and extend the plants.

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.
