Siddipet district holds the third phase of Genome Valley at Karkapatla, where vaccine and biologics plants are being built, and a planned food-processing zone around Gajwel. We manufacture and electropolish SS 316L and 304L pipes and tubes and quote against your drawings from design stage, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Siddipet is a district town about 100 km north-east of Hyderabad, on the road to Karimnagar. Industry here falls into two very different groups. The first is Karkapatla, in Markook mandal, developed as Biotech Park Phase III, the third phase of Genome Valley after Turkapally and Lalgadi Malakpet, housing high-containment biologics and veterinary-vaccine plants. The second is food and agro around Gajwel, where a special food-processing zone has been planned. Siddipet town itself is well known for handloom weaving and local MSME units.
A word on fit. Handloom and most grain and cotton processing are dry or craft processes and don't need electropolished pipe. Where we're useful is the biotech and vaccine side at Karkapatla, wet food lines in any food zone, and the fabricators and EPC contractors serving both.

316L with a smooth internal surface, verified passivation and full traceability.
Electropolished tube cut to your drawing, in the sizes your skid makers and orbital-welding contractors specify.
Quotes against your drawings and specification, with the document pack you'll need for commissioning.
A smooth, passivated interior that cleans easily and doesn't hold residue, for any food-zone plants that get built.
Cut-to-length pipe with heat-number traceability for the shops and contractors who build for Karkapatla and Gajwel.
A smooth bore cleans faster and drains better.

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.
