Product Description

Weld Neck Gr3 Gr4 Pn10 Titanium Pipe Flange 0.375"-100" ASME B16.5

The weld neck design of this flange provides a strong and reliable connection. It features a long tapered neck that is butt-welded to the pipe, ensuring a smooth transition and reducing turbulence. This design is preferred for high-pressure and high-temperature applications where the flange needs to withstand significant stress.

The flange's titanium construction makes it well-suited for applications where corrosion resistance is critical, such as in chemical processing, offshore installations, and other corrosive environments. Titanium's lightweight nature and excellent strength-to-weight ratio also make it advantageous in applications where weight reduction is desired, such as aerospace and marine applications.

It's important to note that specific dimensions, tolerances, and other specifications may vary depending on the manufacturer and customer requirements. It's recommended to consult with us to ensure that the specific details and specifications of the weld neck flange meet your application's needs.
