Paradip is eastern India's premier deep-water port hub and petrochemical investment region (PCPIR), anchored by major oil refining, petrochemical, fertiliser and polymer clusters along the Bay of Bengal. We manufacture and electropolish SS 316L and duplex 2205 pipes and tubes and supply Paradip's coastal plants, refineries and EPC contractors directly, with MTC EN 10204 3.1, 100% PMI testing and a measured Ra report on every order.
Paradip represents Odisha's major maritime gateway and petroleum, chemicals and petrochemical investment region (PCPIR). Its heavy industrial landscape includes a 15 MMTPA integrated oil refinery, large phosphatic fertiliser complexes, carbon black units, and an emerging plastic park.
A word on fit. Heavy crude refining, bulk fertiliser production and cargo handling rely primarily on carbon steel and specialty nickel alloys. Where Sakshi Forge is critical is high-purity clean utilities: DM water, boiler-feed analysis lines, process sampling loops, marine-grade saline utility lines, and hygienic process lines inside downstream polymer and packaging units.

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.
