Product Specification

ASME B16.5 Titanium Gr2 Gr5 Weld Neck Flanges (WN Flanges) Raised Face Class 150 for Water Supply System Applications

In water supply systems, the need for durable, corrosion-resistant, and high-performance components is essential. ASME B16.5 Titanium Gr2 and Gr5 Weld Neck Flanges (WN Flanges) with a Raised Face Class 150 design are among the most reliable and widely used solutions for such systems. These flanges, made from premium titanium materials, offer unparalleled benefits for water supply applications where performance and longevity are critical.

1. Overview of ASME B16.5 Titanium Weld Neck Flanges

ASME B16.5 Titanium Weld Neck Flanges are designed to provide a reliable connection between pipes and other piping components, especially in systems that require high strength and resistance to corrosion. Titanium grades Gr2 and Gr5 are particularly suitable for demanding environments, such as water supply systems, where corrosion, high pressure, and varying temperatures can compromise other materials.

• Titanium Grade 2 (Gr2) is a commercially pure titanium, offering excellent corrosion resistance, high strength, and good weldability. It is ideal for low to medium-pressure applications where seawater or other aggressive environments are present.

• Titanium Grade 5 (Gr5), an alloy of titanium with aluminum and vanadium, is known for its high strength and exceptional corrosion resistance. It is typically used in higher-pressure applications and provides superior durability compared to Grade 2.

2. Product Features and Advantages

The ASME B16.5 Titanium Gr2 Gr5 Weld Neck Flanges are known for several advantages that make them particularly effective for water supply systems:

3. Applications in Water Supply Systems

Titanium Weld Neck Flanges are increasingly being used in water supply systems due to their resistance to corrosion, especially in desalination plants, sewage treatment, and municipal water pipelines. The raised face design, commonly used in these applications, allows for a more effective seal and better pressure resistance.

Some typical applications include:

• Desalination plants: Titanium’s exceptional resistance to seawater corrosion makes it a top choice for systems that process seawater to provide fresh water.
• Wastewater treatment plants: Gr2 titanium flanges resist the aggressive chemical properties often present in wastewater systems.
• Municipal water pipelines: Both Gr2 and Gr5 titanium alloys ensure long service life and low maintenance in potable water pipelines.

4. Class 150 Pressure Rating

ASME B16.5 Class 150 flanges are designed for moderate-pressure systems, typically with pressure ratings up to 150 psi at 100°F (37.8°C). This is ideal for many water supply applications, ensuring that the system can handle standard pressures commonly encountered in water systems without compromising the safety or performance of the system.

This table highlights the pressure rating variations with temperature, showing the typical performance limits for Class 150 flanges in water systems.

5. The Raised Face Design Advantage

The raised face design (RF) of the titanium Weld Neck Flanges ensures a more secure and leak-proof seal. The raised face is designed to increase the contact area between the flange and the gasket, ensuring better sealing performance under pressure. This feature is particularly important in water supply systems, where the risk of leakage can lead to water loss and other complications. The raised face also improves the reliability of the connection in fluctuating pressure conditions.

6. Why Choose Titanium for Water Supply Systems?

Titanium’s exceptional combination of properties makes it the material of choice for many water supply systems:

• Exceptional Corrosion Resistance: Titanium naturally forms a protective oxide layer that makes it highly resistant to corrosion from water and chemicals.
• High Strength: Titanium has an impressive strength-to-weight ratio, making it suitable for systems that require both structural integrity and lightness.
• Long Service Life: With minimal wear and corrosion, titanium components offer a long service life, making them a cost-effective choice in the long run.
• Eco-Friendly: Titanium is a sustainable material, as it is highly recyclable and durable, contributing to environmentally friendly operations.

Conclusion

The ASME B16.5 Titanium Gr2 and Gr5 Weld Neck Flanges with Raised Face Class 150 are an outstanding solution for water supply systems, offering an array of advantages, including excellent corrosion resistance, high strength, minimal maintenance, and long-term durability. Whether used in desalination plants, wastewater treatment, or municipal pipelines, these titanium flanges provide a reliable, leak-proof connection that ensures the integrity and performance of the water supply system. Their combination of strength, lightweight, and superior sealing capabilities make them an ideal choice for demanding applications in the water industry.
