Sachin Steel Product Banner_21 Aug_001

Titanium Flanges are used in piping systems that are in contact with seawater, chlorides and aggressive process conditions, providing an image of low density, high strength and corrosion resistance. The density of titanium is around 56% of carbon steel with approximately 4.51 g/cm³, and commercially pure and alloy grades have tensile strength appropriate for challenging industrial applications. Titanium Flanges are made in various grades including Grade 1, Grade 2, Grade 5 and Grade 7 in a range of configurations including weld neck, slip-on, blind, socket weld, threaded and lap joint. They may be provided according to the dimensional specification of ASME B16.5 in various pressure classes, sizes and facing choices. Sachin Steel Centre is a leading manufacturer and supplier of Titanium Flanges in India for oil & gas, chemical processing, marine, heat exchanger and power applications.
