Titanium Slip On Pipe Flange Ti Gr2 Gr5 ASME B16.5 SO Flange Class 150 SORF Raised Face for Chemical Industry
1.Product Introduction of ASME B16.5 Titanium Slip On Flange
Titanium slip-on flanges, conforming to ASME B16.5 standards and made from Grade 2 titanium alloy, play a crucial role in the oil and gas industry. These flanges with raised faces are designed to ensure secure and leak-free connections in pipelines and equipment subjected to high pressures and corrosive environments. This paper examines the specifications, characteristics, and applications of ASME B16.5 Grade 2 Class 150 titanium slip-on flanges with raised face, highlighting their significance in enhancing operational efficiency and reliability within the oil and gas sector.
The oil and gas industry relies heavily on robust and durable components to maintain the integrity of pipeline systems and equipment. Titanium slip-on flanges are preferred for their exceptional corrosion resistance and mechanical properties, making them suitable for demanding applications in offshore platforms, refineries, and chemical processing plants. This paper explores the structural composition, dimensional standards, and performance attributes of ASME B16.5 Grade 2 Class 150 titanium slip-on flanges with raised face, detailing their role in addressing challenges related to fluid transport, high temperatures, and aggressive media encountered in oil and gas operations.
The ASME B16.5 standard covers dimensions and tolerances for pipe flanges and flanged fittings from NPS 1/2 through NPS 24, used in process industries. A titanium slip-on flange (SO flange) conforming to ASME B16.5 is specifically designed for use with titanium pipes or pipes with titanium alloy components.
Titanium slip-on flanges are typically manufactured using commercially pure titanium (Grade 2) or titanium alloys such as Grade 12. These flanges are forged or fabricated from titanium plates, ensuring high strength and corrosion resistance suitable for various industrial applications. The slip-on flange has a slightly larger inner diameter than the outer diameter of the pipe it is intended to fit over. It is easy to align and weld, providing a smooth bore and good flow characteristics. ASME B16.5 specifies a raised face (RF) design for slip-on flanges, which helps create a seal when bolted to a corresponding flange or fitting.

4. Why We Choose Titanium Flanges
Weight Reduction: Titanium alloys used in flanges offer excellent strength-to-weight ratios, making them highly desirable in aerospace. Engineers often aim to reduce aircraft weight while maintaining strength to enhance fuel efficiency and flight performance. Titanium flanges contribute significantly to achieving this goal by reducing overall structural weight.
Corrosion Resistance: Titanium flanges exhibit outstanding corrosion resistance, particularly against chloride ions prevalent in marine environments. Aircraft and helicopters operating in such conditions require components with robust corrosion resistance, where titanium flanges play a vital role.
High Temperature Performance: Titanium flanges maintain strength and stability at high temperatures, making them suitable for applications such as engine components, gas turbines, and jet engines that demand heat-resistant materials. They withstand high-temperature airflow and heat emissions while maintaining structural integrity and functionality.
High Strength Requirements: Titanium flanges' high strength enables them to withstand dynamic loads and mechanical stresses typical in aviation, ensuring flight safety and structural reliability. They are commonly used in critical connections such as landing gear, wing assemblies, structural components, and flight control systems.
Wear and Fatigue Resistance: Titanium alloys offer excellent fatigue and wear resistance, critical for aerospace applications subjected to frequent use and high-intensity operations. Titanium flanges maintain stable performance over extended periods, reducing the risk of damage and failure due to fatigue and wear.
5. Packages of Titanium Slip On 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.
6. Applications of ANSI B16.5 Titanium Slip On Flange
- Pipeline Construction: Used to join sections of pipelines, ensuring secure and leak-free connections during fluid transport.
- Refineries and Petrochemical Plants: Installed in processing units for connecting vessels, reactors, and heat exchangers, where resistance to corrosive chemicals is essential.
- Offshore Platforms: Employed in offshore drilling rigs and production platforms to withstand marine environments and harsh weather conditions.
- Gas Processing Facilities: Utilized in compressors, pumps, and valves to maintain operational integrity and safety.
