Product Description
Grade 2 Titanium Raised Face Weld Neck Flanges
Grade 2 Titanium Raised Face Weld Neck Flanges (WNRF) for Water Supply Systems
1. Basic Dimensions of Class 300 Raised Face Weld Neck Flanges (WNRF)
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.
| Nominal Pipe Size (NPS) | Bolt Circle Diameter (BC) | Number of Bolts | Flange Thickness (T) | Face Width (F) | Bore (ID) |
|---|---|---|---|---|---|
| 1/2" | 2.62" | 4 | 0.88" | 0.50" | 0.84" |
| 1" | 3.25" | 4 | 1.00" | 0.56" | 1.05" |
| 2" | 4.50" | 8 | 1.12" | 0.75" | 2.07" |
| 4" | 7.00" | 8 | 1.56" | 1.00" | 4.09" |
| 6" | 9.00" | 12 | 1.81" | 1.25" | 6.13" |
| 12" | 14.00" | 16 | 2.44" | 1.50" | 12.13" |
| 24" | 22.00" | 20 | 3.13" | 2.00" | 24.13" |
2. Titanium Grades: Material Properties of Grade 1 and Grade 2 Titanium
Comparison of material properties for Grade 1 and Grade 2 titanium alloys, commonly used in manufacturing Class 300 raised face weld neck flanges (WNRF).
| Property | Grade 1 Titanium | Grade 2 Titanium |
|---|---|---|
| Composition | 99.5% pure titanium | Titanium with small amounts of iron and oxygen |
| Tensile Strength (ksi) | 35-45 ksi | 50-60 ksi |
| Yield Strength (ksi) | 20-30 ksi | 40-50 ksi |
| Elongation | 24% | 20% |
| Hardness (Brinell) | 120 | 140 |
| Density (g/cm³) | 4.51 | 4.51 |
| Corrosion Resistance | Excellent, especially in fresh and marine waters | Excellent, superior in chloride environments |
| Applications | Less demanding, non-pressurized systems | Higher pressure systems, industrial water supply |
- 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.
3. Bolt Size and Torque Specifications for Class 300 Titanium Flanges
Proper bolt selection and torque application are essential to ensure a secure, leak-free connection between flanges.
| Nominal Pipe Size (NPS) | Bolt Size (inches) | Number of Bolts | Torque (ft-lbs) |
|---|---|---|---|
| 1/2" | 5/8" | 4 | 40-50 |
| 1" | 3/4" | 4 | 50-70 |
| 2" | 7/8" | 8 | 70-90 |
| 4" | 1-1/8" | 8 | 100-120 |
| 6" | 1-1/4" | 12 | 130-160 |
| 12" | 1-1/2" | 16 | 200-250 |
| 24" | 1-3/4" | 20 | 350-400 |
- 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.
