What Special Flanges does

Special Flanges S.p.A. is an Italian forging specialist founded in 1984 and headquartered in Cesano Maderno, Italy. The company manufactures custom-engineered forged components — including flanges, rings (up to 8,000mm diameter), discs, nozzles, tubesheets (up to 1,000mm thickness), Y-branch tees, shafts, blocks, and shaped forgings (up to 30 tonnes) — across carbon steels, low alloy steels, stainless steels (including duplex and super duplex), nickel alloys, and titanium. Operations span three integrated facilities: a forging shop in Legnano (25,000m2) housing five presses (500T to 5,000T) and four ring rolling machines, a raw materials warehouse in Gorla Minore (40,000m2) stocking more than 15,000 tonnes of European base materials, and a headquarters/machining complex in Cesano Maderno with 50+ CNC machines, a five-axis machining center, and an in-house metallurgical quality and test laboratory.

The business operates as a B2B engineered-to-order manufacturer serving industrial customers in hydrogen, LNG and regasification, power generation (nuclear and renewables), conventional oil and gas (onshore, offshore, petrochemical), bio-refineries, cryogenics, marine, pharmaceutical, food, fertilizers, and plastic pyrolysis. Revenue is generated through custom, quote-based component orders priced on complexity, material grade, and specification, with an additional recurring stream from an ancillary warehouse stocking more than 100,000 standard flanges for rapid dispatch. Distribution is direct to enterprise customers across approximately 90 countries via the company's own logistics. The customer base exceeds 600 active clients and the company maintains a comprehensive certification portfolio (ISO 9001:2015, ABS, Bureau Veritas, DNV GL, RINA, Lloyd's Register, TUV Nord, NORSOK QTR series, Korean Register, BIS).

Since October 2021 Special Flanges has been backed by Italian private equity firm Wise Equity, which funded the June 2025 acquisition of Vilmar to extend manufacturing capacity. The company employs just over 100 people, is organized as an Italian Società per Azioni, and adopted Italian Legislative Decree 231/2001 governance (Model 231, Code of Ethics, Whistleblowing System) in 2022.
