STANDARD FLANGES

Diameter: up to 100”
Weight: up to 25 tons

Flanges are mechanical joints used for the installation of pipes and equipment in almost all sectors. (Not necessary to explain as those interested would know what a Flange is)

SPECIAL FLANGES SpA supply Flanges to a variety of standards including: ANSI B16.5, ANSI B16.36, ANSI B16.47 TYPE A and B, EN1092-1, BS 1759-1, BS 3293, API 605, API 6A, API 6BX, NORSOK standard L-005, DIN flanges. SPECIAL FLANGES SpA can also forge and supply other kinds of Flanges such as: Anchor flanges, Drip rings, Spectacle Flanges, Taylor flanges, GOST Flanges, Orifice flanges.
