Veer Flanges stands out as a top manufacturer and supplier of Titanium Long Weld Neck Flanges right in Kolkata, India. We specialize in precision-engineered flanges that are perfect for high-performance, corrosive, and critical applications. Our flanges feature an extended neck that smoothly transitions into the piping, ensuring excellent reinforcement and stress distribution. Crafted from high-purity titanium grades like Gr 2 and Gr 5, our products meet rigorous standards such as ASTM B381 and ASME B16.5. These Titanium Long Weld Neck Flanges are widely utilized in industries like aerospace, chemical processing, marine, desalination, and offshore oil & gas, thanks to their remarkable strength-to-weight ratio and resistance to corrosion.
Typically, Titanium Long Weld Neck Flanges are made from Grade 2 (commercially pure titanium) or Grade 5 (Ti-6Al-4V). Grade 2 is known for its excellent corrosion resistance, while Grade 5 shines with superior strength and heat resistance. These flanges boast tensile strength ranging from 345 MPa (Gr 2) to 895 MPa (Gr 5), yield strength up to 828 MPa, and elongation of 20–30%. With a low density of 4.5 g/cm³, outstanding fatigue resistance, and a non-magnetic nature, titanium is the go-to choice for applications that demand strength, lightweight properties, and resistance to harsh substances like chlorides and acids.
