ASME B16.5 Titanium Flanges:

ASME B16.5 is a widely recognized standard developed by the American Society of Mechanical Engineers (ASME), governing the design, dimensions, and materials for flanges and flanged fittings used in piping systems. The ASME B16.5 standard applies to flanges with nominal pipe sizes from 1/2 inch to 24 inches, and it covers various flange types, such as weld neck, slip-on, blind, and socket weld, across different pressure classes (e.g., 150#, 300#, 600#, etc.).

When it comes to titanium flanges—specifically those made from titanium alloys such as Grade 2 Titanium (Ti Gr 2) or Grade 5 Titanium (Ti-6Al-4V)—the ASME B16.5 standard ensures that the flanges meet essential requirements for mechanical performance, dimensional tolerances, and pressure ratings, while offering the unique benefits of titanium, such as lightweight, corrosion resistance, and high strength-to-weight ratio.

1. Material: Ti Gr 2 (Grade 2 Titanium)

• Titanium Grade 2 (Ti Gr 2) is a commercially pure titanium with excellent corrosion resistance, particularly in marine environments, chemical processing, and aerospace.
• Grade 2 Titanium is widely used for applications requiring moderate strength and high corrosion resistance.
• Mechanical Properties (approximate values):
  • Tensile Strength: 345–450 MPa (50–65 ksi)
  • Yield Strength: 275 MPa (40 ksi)
  • Elongation: 20–30%
  • Corrosion Resistance: Very good, especially in saltwater, acids, and chlorides.

2. Flange Type: Slip-On

• Slip-On Flange is a type of flange designed to slide over the pipe. This type of flange allows easy alignment and is often used in systems where welding is required to hold the flange in place.
• Key Features:
  • Slip-on flanges are cost-effective and easy to install.
  • They are generally welded inside and outside to ensure proper sealing and strength.
  • Suitable for low- to medium-pressure applications.

3. Nominal Size: 1/2"

• The flange is designed to fit a pipe with a nominal diameter of 1/2 inch.
• This size is commonly used in smaller piping systems and in applications where a compact, lightweight solution is needed.

4. Pressure Class: 150#

• The 150# pressure class (Class 150) indicates the pressure rating of the flange at a given temperature. This class is commonly used for lower pressure applications.
• The Class 150 flanges are rated to handle 150 psi at room temperature, with the pressure rating decreasing at higher temperatures.
• Working Pressure: Class 150 flanges are typically used in systems with pressures up to 150 psi and are suitable for both liquid and gas applications.

5. Standards: ASME B16.5

• ASME B16.5 is a standard developed by the American Society of Mechanical Engineers (ASME) that defines the specifications for flanges and flanged fittings for piping systems. It includes details on dimensions, pressure-temperature ratings, and material requirements.
• This standard is widely adopted for both industrial and commercial use and ensures compatibility across different systems and manufacturers.

Advantages of Ti Gr 2 Titanium for Flanges

• Corrosion Resistance: Grade 2 titanium is resistant to a wide range of chemicals, including seawater, acids, and chlorides.
• Lightweight: Titanium is lightweight compared to other metals, which can help reduce the weight of the overall piping system.
• Biocompatibility: If used in medical or pharmaceutical applications, titanium’s biocompatibility makes it suitable for contact with bodily fluids.
• Strength-to-Weight Ratio: While not as strong as Grade 5 titanium, Grade 2 provides a good balance of strength and weight for many applications.

Applications of Ti Gr 2 Flanges

• Marine: Often used in marine piping systems due to its excellent resistance to saltwater corrosion.
• Chemical Processing: Ideal for systems that transport aggressive chemicals or acidic substances.
• Aerospace: Sometimes used in aerospace applications where lightweight, high-strength, and corrosion-resistant materials are required.
• Medical: Suitable for medical devices and systems that come into contact with human tissue or bodily fluids.
• Food and Beverage: Can be used in food processing plants, where non-reactive materials are necessary.

Summary

• Flange Type: Slip-on flange, easy to install and weld.
• Material: Ti Gr 2 (commercially pure titanium) offering excellent corrosion resistance.
• Pressure Rating: Rated for Class 150, making it suitable for low-pressure systems.
• Nominal Size: 1/2", ideal for smaller pipelines and systems.
• Standard: Manufactured according to ASME B16.5, ensuring compatibility with other standard components.
