Siddhagiri Metals and Tubes is a manufacturer and supplier of Titanium Flanges. These Titanium Flanges are manufactured as per ASTM B381 specification and ASME / ANSI B16.5, ASME B16.47 / API 605, ASME B16.48 / API 590, MSS-SP-44, BS 3293, API 6A, DIN DN10 to DN3600 dimension standards.
A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. The principle of a flange is to apply a mechanical force by using bolts to preload the gasket until contact stress between flanges and gasket is sufficient to maintain a seal. Connection to the pipe is by welding or threading. To allow easy functionality and inter-changeability, these ASTM B381 Flanges are designed to have standardised dimensions which include ANSI, ASME, DIN, EN, BS, JIS. Flanges have major applications in Oil, Gas, Petrochemical, Ship-Building, Marine, Food, Dairy, Railways and other associated industries were piping systems are required.
Titanium Slip On Flange — Alloy Slip-On Flanges is slightly larger than the outer diameter of the pipe it is to be used with. The pipe is slipped into the Flange prior to welding both inside and outside. We supply a wide range of slip-On Flanges in different dimensions and sizes.
Titanium Blind Flange — Alloy Flange with no borehole are known as Blind Flange and used to close the end of the pipe. Blind Flanges are supplied as threaded or welded from class 150lb to 2500lb.
Titanium Weld Neck Flange — Alloy Weld Neck Flanges are widely used in high-pressure piping systems and can be easily recognised by the long tapered hub. The size of the bore hole is usually equal to the size of the pipe.
Titanium Socket Weld Flange — Initially developed for small high-pressure piping systems a Socket Weld Flange is similar to Slip On Flange. The flange is installed by welding around the hub of the flange.
Titanium Threaded Flange — Threaded Flanges are used for special application where the flange can be assembled to the piping system by without welding. We specialise in all forms of threaded flanges and can supply it in multiple size range.
Titanium Lap Joint Flange — Lap-Joint Flanges are similar to Slip-On flanges and are generally used with Lap-Joint Stubs. This type of flange is highly used where the piping systems are disassembled from time to time.
Siddhagiri Metals and Tubes supplies Titanium Flanges in different sizes and pressure ratings. Our production stock of Titanium Alloy Flanges includes size range from 1/2” to 24”, 26” to 60”, 1” to 24”, 1/2” to 24”, 12” to 60”, 26” to 48”, 21/16” to 30”, DN10 to DN3600.

Properties of Titanium Grade 1 alloy
Titanium Grade 1 Cold Forming
Titanium is similar to moderately tempered austenitic stainless steel. In multiple cold forming operations, intermediate stress relief is recommended. To reattain optimum performance of this material post-work annealing is required.
Titanium Grade 1 Hot Forming
Hot working increases the overall ductility of this Titanium.
Titanium Grade 1 Welding
Titanium is rated well in terms of weldability. Standard welding practices can be carried out easily with this grade.
