Key Features of ANSI B16.5 Titanium Slip-On Flange
The ANSI B16.5 Titanium Slip-On Flange is a type of flange designed
to meet the ANSI B16.5 standard, which covers flanges and flanged
fittings for pipe sizes ranging from 1/2 inch to 24 inches. The
Slip-On Flange (SO flange) is a popular flange type where the pipe
is slid into the flange and welded on both the inside and outside,
providing a strong and leak-tight seal. When made from titanium,
these flanges offer numerous advantages, especially in highly
corrosive or high-performance applications.
Here are the key features of the ANSI B16.5 Titanium Slip-On
Flange:
1. Material Composition
- Titanium Grades: Typically manufactured from Grade 2 (commercially
pure titanium) or Grade 5 (Ti-6Al-4V alloy) titanium.
- Grade 2 Titanium: Offers excellent corrosion resistance and is
commonly used in chemical processing, marine, and other demanding
environments.
- Grade 5 Titanium: A titanium alloy with aluminum and vanadium,
providing higher strength, making it suitable for aerospace and
industrial applications.
- Corrosion Resistance: Titanium is highly resistant to corrosion
from a wide range of aggressive substances, such as seawater,
acids, alkalis, and chlorides. This is a significant benefit in
applications where other materials may fail due to corrosion.
2. Design and Structure
- Slip-On Design: The slip-on flange is designed to be easily
installed by sliding the pipe into the flange. The flange is then
welded both on the inside and the outside to secure the pipe. This
design makes installation relatively simple and cost-effective.
- Bolt Holes and Centering: The ANSI B16.5 specification includes
standardized bolt holes and dimensions to ensure compatibility with
other components in the piping system. The holes are positioned
according to the standard bolt circle diameter (BCD), ensuring a
reliable connection.
- Raised Face (RF) or Flat Face (FF): Typically, the slip-on flange
comes with a raised face to provide a better sealing surface when
paired with a gasket. The raised face helps to achieve a leak-proof
seal under pressure.
3. Pressure and Temperature Ratings
- Pressure Rating: The ANSI B16.5 standard specifies pressure ratings
for flanges based on their size and material. Titanium slip-on
flanges are suitable for various pressure classes, such as 150#,
300#, 600#, and 1500#, depending on the specific design and
material grade.
- Temperature Resistance: Titanium is known for its ability to
withstand high temperatures. Grade 2 Titanium can handle
temperatures up to 400°C (752°F), while Grade 5 Titanium can
operate in temperatures up to 500°C (932°F), depending on the
application. This makes titanium slip-on flanges ideal for
high-temperature systems in power generation, chemical processing,
and aerospace.
4. Lightweight and High Strength
- Reduced Weight: Titanium is significantly lighter than many other
metals, such as stainless steel or carbon steel. This reduces the
overall weight of the piping system, making it easier to handle and
transport, especially in large-scale installations or offshore
projects.
- High Strength-to-Weight Ratio: Titanium has an excellent
strength-to-weight ratio, meaning that even with its lower weight,
titanium can still provide exceptional strength and support for
pressure systems.
5. Durability and Longevity
- Corrosion Resistance: Titanium’s resistance to corrosion in
aggressive environments, including seawater, acids, and chlorides,
ensures a long service life in applications such as chemical
processing and marine systems.
- Wear Resistance: Titanium’s resistance to erosion, cavitation, and
wear makes these flanges particularly useful in abrasive or harsh
conditions where other materials might degrade quickly.
6. Easy Installation and Maintenance
- Slip-On Design for Quick Installation: The slip-on flange allows
for quick and easy installation, as it simply slides onto the pipe
before being welded. This reduces labor time and makes it a
cost-effective choice for many applications.
- Minimal Maintenance: Once installed, titanium slip-on flanges are
low-maintenance due to the material’s inherent resistance to
corrosion and wear. This helps reduce operational downtime and
maintenance costs.
7. Compatibility with Gaskets and Bolts
- Standardized Dimensions: As per the ANSI B16.5 standard, the
Slip-On Flange has standardized dimensions, including bolt hole
pattern and center-to-center distances, ensuring compatibility with
other flanges and piping components. This allows easy integration
into existing piping systems.
- Leak-Proof Sealing: When paired with a suitable gasket, titanium
slip-on flanges can provide a strong, leak-proof seal even under
high pressure. The raised face design further enhances sealing
performance.
8. Excellent Weldability
- Weldability: Titanium is highly weldable, and ANSI B16.5 Titanium
Slip-On Flanges are designed to be welded easily, ensuring a strong
connection between the pipe and the flange. The welds are also
resistant to corrosion, ensuring long-term reliability.
- Corrosion-Resistant Welds: Titanium’s resistance to corrosion
extends to the welded joints, ensuring that the connection remains
secure and leak-free over time.
9. Versatility and Applications
- Chemical Processing: Titanium slip-on flanges are ideal for
chemical systems where resistance to aggressive chemicals, acids,
and solvents is necessary.
- Marine and Offshore: Titanium’s excellent performance in seawater
makes these flanges ideal for marine applications, such as offshore
oil and gas platforms, desalination plants, and shipbuilding.
- Aerospace: Due to its strength and low weight, titanium slip-on
flanges are used in aircraft fuel systems, hydraulic systems, and
other aerospace applications.
- Power Generation: These flanges are used in high-pressure and
high-temperature applications, such as heat exchangers, steam
turbines, and other critical components in power plants.
- Pharmaceutical and Food Industries: Titanium’s non-reactivity makes
it suitable for use in sanitary piping systems in the
pharmaceutical and food industries, where hygiene and
contamination-free operations are paramount.
Advantages of ANSI B16.5 Titanium Slip-On Flange
