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
