Hassan hosts a dedicated pharmaceutical SEZ and a food-processing SEZ, set in a spice, coconut and coffee district. We manufacture and electropolish SS 316L and 304L pipes and tubes and supply Hassan's plants directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Hassan is an industrial growth centre with several developed industrial areas and special economic zones. Two matter most for electropolished pipe. The KIADB Pharmaceutical SEZ is a zone dedicated to pharma manufacturing, and a parliamentary reply in December 2024 listed seven units in it. The Hassan Food Processing SEZ, a KIADB zone of about 265 acres for export-oriented units, covers food and agro processing. Beyond the SEZs, the Hassan Industrial Area and its sub-layouts, and a new industrial area planned at Dhutanooru Kaval in Channarayapatna, host smaller manufacturers. The district also grows spices such as cardamom, and coconut and coffee. A word on fit: Spice, coconut and coffee handling is mostly dry, which doesn't call for electropolished pipe. Where we're useful is the pharma SEZ, wet and dairy-style food lines, and new-build or expansion projects.

316L with a smooth internal surface and verified passivation, for the pharma SEZ.
A smooth, passivated interior that cleans easily and doesn't hold residue, for plants that wash, blend or heat their product.
Hygienic tubing for milk transfer and CIP.
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.
