Titanium Grade 2 Long Weld Neck Flange is a high-quality flange designed for applications that require a seamless connection to pipes, offering superior strength and corrosion resistance. This type of flange features an extended neck that provides added support and stability in high-pressure and high-temperature environments, making it ideal for industries like chemical processing, aerospace, marine, and oil & gas. Manufactured from commercially pure titanium, Titanium Grade 2 offers excellent resistance to oxidation and corrosion, particularly in harsh environments. Hex Forge Inc. is a trusted supplier and manufacturer of Titanium Grade 2 Long Weld Neck Flange, delivering reliable products to meet industrial needs.

The chemical composition of Titanium Grade 2 consists of 99.2% titanium, with small amounts of iron, carbon, oxygen, and nitrogen. This composition gives the material a balance of high strength, lightweight properties, and excellent formability. For projects requiring higher strength and durability, offering increased tensile strength and fatigue resistance. Both grades are widely used across various applications, but Titanium Grade 2 is preferred for its cost-effectiveness and corrosion resistance in less demanding conditions
