ASME B16.5 Class 150 Titanium Weld Neck Flanges WNRF Grade 1 Grade 2 For Industrial Applications

1. ASME B16.5 Titanium Weld Neck Flanges Class 150:

ASME B16.5 is a standard developed by the American Society of Mechanical Engineers (ASME) that provides specifications for pipe flanges and flanged fittings. The standard covers a range of materials, including titanium, and provides dimensions, tolerances, and pressure-temperature ratings for flanges.

When titanium is specified for flanges according to ASME B16.5, it typically refers to titanium alloy flanges that meet the mechanical and chemical requirements set forth by the standard. Titanium is often used in these applications due to its high strength-to-weight ratio, excellent corrosion resistance (especially in corrosive environments like seawater and chemicals), and lightweight properties.

2. Key Characteristics of ASME B16.5 Titanium Weld Neck Flanges Class 150

Pressure Rating (Class 150): The pressure rating refers to the maximum pressure a flange can withstand under normal operating conditions at a given temperature. Class 150 flanges are designed for moderate pressure systems, typically used in systems operating at pressures up to 150 psi at ambient temperature.

Temperature Range: ASME B16.5 specifies pressure ratings at various temperatures, and for Class 150 flanges, the pressure decreases as the temperature rises. Titanium has excellent performance at higher temperatures compared to many other materials.

Weld Neck Design: The weld neck flange is characterized by a long tapered neck that allows for a smooth and strong connection to the pipe, minimizing stress concentration. This is especially important in high-pressure applications like those where titanium is used, as it ensures a more robust joint under high pressure and temperature conditions.

Dimensions: The dimensions of the flange, including the outside diameter, bolt hole diameter, and thickness, are specified in ASME B16.5, with strict tolerances to ensure that the flange fits properly with the associated pipe and other flanged components.

3. Physical Properties of Titanium

Density: Titanium is much lighter than steel, which makes it advantageous in applications where weight is a concern (e.g., aerospace, offshore oil rigs).

Tensile Strength: While not as high as some steel alloys, titanium has a high tensile strength relative to its weight, making it useful in pressure-containing applications.

Corrosion Resistance: Titanium is highly resistant to corrosion, especially in chloride environments like seawater, making it highly valuable in marine and chemical industries.

Thermal Conductivity: Titanium’s thermal conductivity is relatively low, making it suitable for applications where high thermal resistance is desirable.

4. Benefits of Titanium Weld Neck Flanges (Class 150)

Corrosion Resistance: Titanium flanges are highly resistant to corrosion, especially in harsh environments like seawater, acidic or chemical processing systems.

Lightweight: Titanium flanges are much lighter compared to steel, which is advantageous in applications where weight reduction is important, such as in aerospace or offshore platforms.

Durability and Strength: Titanium is known for its strength and fatigue resistance, which makes it suitable for high-stress and high-temperature environments.

Improved Service Life: Due to its ability to resist corrosion, titanium flanges tend to have a much longer service life, reducing maintenance costs over time.

5. Applications of ASME B16.5 Titanium Weld Neck Flanges Class 150

Chemical Processing: Titanium's resistance to corrosion in aggressive chemicals makes it suitable for piping systems handling acids, alkalis, and other corrosive substances.

Aerospace: Titanium is used in aircraft components due to its lightweight and high-strength properties.

Offshore & Marine: Titanium flanges are commonly used in offshore oil rigs and marine applications where resistance to seawater corrosion is essential.

Power Generation: In high-temperature, corrosive environments like nuclear power plants or geothermal facilities, titanium flanges offer the necessary durability.

The LHTi Titanium flange is highly reliable and suitable for different applications. It offers high strength and durability, making it a cost-effective solution for different industries. With a supply ability of 10000, the product is readily available to meet the needs of different customers.
