ASME B16.5 Ti Gr 2 Titanium Flange Gr7 Slip On Flange 1/2" Class
150# 1/2" Seamless Pipe
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.
