Sangareddy district is Hyderabad's western industrial belt, with pharma and chemical estates at Patancheru, Pashamylaram and Bollaram, a medical-devices park at Sultanpur and a large new industrial area at Zaheerabad. We manufacture and electropolish SS 316L and 304L pipes and tubes and supply the district directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Sangareddy is the district headquarters on the Pune–Hyderabad highway, and the industry around it falls into three groups. The first is the pharma and chemical belt at the Hyderabad end of the district: the Patancheru industrial area is the oldest estate, Pashamylaram is one of the main pharma and medical-manufacturing zones around Hyderabad, and IDA Bollaram in Jinnaram mandal, Gaddapotharam, Gummadidala, Bonthapally and Khazipally list pharma and other manufacturers. The second is the Telangana Medical Devices Park at Sultanpur, a purpose-built estate with dozens of companies committed to it. The third is the Zaheerabad Industrial Area, a 3,245-acre smart industrial area on National Highway 65 under the Hyderabad–Nagpur Industrial Corridor.
A word on fit. Many plants in the pharma belt make bulk drugs by chemical synthesis, and their reactor-side solvent and acid lines can need other materials. Where we're useful is the clean side: purified water, WFI, clean utilities, laboratory lines, formulation lines and the clean-water systems of medical-device plants. Zaheerabad is a design-stage market, so we quote against drawings there.

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.
