Warangal is Telangana's second city and home to the Kakatiya Mega Textile Park, the country's first operational PM MITRA park, set in a cotton-growing region with rice, chilli and food processing around it. We manufacture and electropolish SS 316L and 304L pipes and tubes and supply Warangal's plants directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Warangal and its twin city Hanamkonda sit about 150 km north-east of Hyderabad, in the heart of Telangana's cotton belt. The region's best-known industrial project is the Kakatiya Mega Textile Park, a 1,200-acre integrated textile cluster near Shayampet, developed under the national PM MITRA scheme as the first fully functional park of its kind in India. The park was planned to house spinning, weaving, processing, garment-making and technical textiles together. Outside the park, the region has rice mills, agro and food processors, and MSME engineering manufacturers.
A word on fit. Spinning, weaving and garment-making are mostly dry. Where we're useful is the wet-processing side of textiles (dyeing, finishing and effluent-side clean lines), food and agro processing, and the fabricators and EPC contractors building these plants. The park is new, so many buyers are still 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.
