Titanium Grade 5 Flanges Manufacturer in India
Titanium Grade 5 Flanges come with high strength, good strength-to-weight ratio, and non-corrosion properties. It is also far stronger than the pure grades of titanium, and thus it is suited to the harsh industrial conditions. Titanium Grade 5 Flanges find extensive applications in piping systems where the high-pressure, high structural strength, and extended lasting services are required. The flanges are good in severe conditions and are commonly applied in aerospace, chemical processing, offshore, power plants, oil and gas, heat exchangers, and high-performance engineering.
What Are Titanium Grade 5 Flanges?
The flanges are manufactured in accordance with the ASTM B381 / UNS R56400 standards by using forged and rolled Ti-6Al-4V alloy. They have high mechanical strength, fair level of corrosion resistance and consistent performance at high pressure and temperature. The flanges weigh very little but are very strong and are used in the critical piping systems of aerospace, marine, chemical plants, offshore platforms, power generation units, and in industries requiring processing facilities where the safety, strength, and long service life are critical.
