Grade 2 Titanium Weld Neck Flange with 3.5 Inch Bolt Circle Diameter and 0.56 Inch Thickness for Water Supply Systems

The following table outlines the standard dimensions for Class 300 Raised Face Weld Neck Flanges (WNRF) across various nominal pipe sizes (NPS), based on ASME B16.5 standards.

Here’s a more detailed table to compare the material properties of Grade 1 and Grade 2 titanium alloys, which are commonly used in the manufacturing of Class 300 raised face weld neck flanges (WNRF).

• Grade 1 Titanium is more corrosion-resistant and less prone to fatigue but is less strong compared to Grade 2 Titanium. It is ideal for less critical applications.
• Grade 2 Titanium is stronger, making it suitable for higher pressure and more aggressive environments, often chosen for industrial water supply and municipal systems.

Proper bolt selection and torque application are essential to ensure a secure, leak-free connection between flanges. The table below provides the bolt size and the torque values for Class 300 Raised Face Weld Neck Flanges (WNRF) made from Grade 1 and Grade 2 titanium.

• Note: Torque values should be adjusted depending on the gasket material used, as titanium has low friction, requiring specific torque values to ensure effective sealing.
