ASME B16.5 Titanium Class 150 Weld Neck Flanges Grade 1 Grade 2 WNRF For Pipeline Systems

ASME B16.5 Titanium Class 150 Weld Neck Flanges Grade 1 Grade 2 WNRF For Pipeline Systems

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

ASME B16.5 Titanium Weld Neck Flanges Class 150 are designed to meet the specifications laid out by the American Society of Mechanical Engineers (ASME), particularly in ASME B16.5 for pipe flanges and flanged fittings. These flanges are commonly used in various industries where high resistance to corrosion and high strength-to-weight ratios are essential, such as in the chemical, aerospace, and power generation sectors.

Standard Overview

ASME B16.5 specifies the dimensions, materials, and pressure-temperature ratings for flanges ranging from 1/2 inch to 24 inches in size, which includes both weld neck flanges and other types of flanges like slip-on, blind, socket weld, and lap joint flanges.

Class 150 indicates the flange's pressure rating at a specific temperature. The "150" refers to the flange's ability to withstand a maximum working pressure of 150 pounds per square inch (psi) at a reference temperature of 100°F (37.8°C).

2. Titanium Material

Titanium alloys are known for their excellent corrosion resistance, especially in aggressive environments like seawater, chlorine, and acids. They also possess a high strength-to-weight ratio, making them ideal for aerospace, chemical processing, and offshore applications.

Common titanium alloys used in flanges include Grade 2 titanium (commercially pure titanium) and Grade 5 titanium (Ti-6Al-4V, an alloy with aluminum and vanadium for enhanced strength).

Titanium flanges typically offer corrosion resistance in environments where stainless steels might fail or require more costly and heavier materials.

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. Advantages of ASME B16.5 Titanium Weld Neck Flanges:

Titanium weld neck flanges offer a range of advantages that make them highly sought after in various industrial applications where performance and durability are crucial.

Corrosion Resistance: Titanium weld neck flanges are highly resistant to corrosion, even in aggressive environments such as seawater, acids, and chlorides. This makes them ideal for industries like chemical processing, marine, and offshore oil and gas where corrosion resistance is critical.

Strength-to-Weight Ratio: Titanium has a high strength-to-weight ratio, making titanium weld neck flanges strong and durable while remaining lightweight. This is advantageous in applications where weight reduction is desirable without compromising strength and performance.

High Temperature Resistance: Titanium weld neck flanges can withstand high temperatures without losing their mechanical properties. They maintain their strength and corrosion resistance at elevated temperatures, making them suitable for applications involving heat and thermal cycling.

Biocompatibility: Titanium is biocompatible and non-toxic, which makes titanium weld neck flanges suitable for use in medical equipment, pharmaceutical manufacturing, and food processing industries where product purity is essential.

Longevity and Durability: Titanium is known for its durability and long service life. Titanium weld neck flanges exhibit excellent resistance to fatigue, erosion, and wear, contributing to reduced maintenance and replacement costs over time.

Excellent Sealing Properties: The smooth surface finish of titanium weld neck flanges, achieved through pickling or machining processes, allows for superior sealing with gaskets or other connecting components. This helps prevent leaks and ensures reliable performance in critical applications.

Compatibility with Other Metals: Titanium weld neck flanges can be easily welded or paired with other metals such as stainless steel or carbon steel, allowing for versatility in design and compatibility with existing systems.

5. Packages of Titanium Weld Neck Flange

Rust Prevention

• VCI (Volatile Corrosion Inhibitor) Wrapping: Titanium flanges are wrapped in VCI paper to prevent any surface corrosion during transit. This material releases a chemical vapor that forms a protective layer on the metal surfaces.
• Grease or Oil Coating: A light layer of grease or oil may be applied to protect the flange surfaces, especially when being shipped over long distances or stored for extended periods.

Physical Protection

• Bubble Wrap or Foam: Each flange is typically wrapped in bubble wrap or surrounded by foam to cushion against impact during transportation.
• Cardboard Separators: When multiple flanges are packed in one box, cardboard separators are used to prevent them from touching and potentially scratching or damaging each other.

Robust Outer Packaging

• Wooden Crates or Plywood Boxes: Titanium flanges are often shipped in wooden crates or plywood boxes, which provide sturdy protection from mechanical damage and are stackable, facilitating easier and safer handling.
• Palletization: For large orders, flanges may be palletized. Each pallet is usually shrink-wrapped to secure the boxes or crates during handling and shipping.

Waterproofing

• Plastic Sheeting: Outer crates or boxes are often covered with thick plastic sheeting to protect against moisture, especially in humid or wet environments.

Labeling and Documentation

• Clear Labeling: Each package is clearly labeled with handling instructions, part numbers, and destination details to ensure proper handling and to facilitate tracking.
• Quality Assurance Documentation: Certificates of quality, material test reports, and compliance certificates are often included in the packaging or provided separately to ensure traceability and compliance with industry standards.
