ASME B16.5 Class 150 Ti Gr1 Gr2 Titanium Flanges: Slip On Flange Raised Face for Industrial Pipelines

Introduction to Titanium Slip-On Flanges:

The ASME B16.5 Slip-On Flange (SO Flange) Class 150 SORF (Slip-On Raised Face) is a popular flange type known for its reliability, ease of installation, and excellent sealing performance, particularly in water supply systems. Rated for Class 150, it is designed to handle pressures up to 150 psi, making it ideal for low to medium pressure water pipelines. The Slip-On design allows the flange to slide easily onto the pipe end, and it is welded on both the inside and outside to ensure a secure and leak-free connection. The Raised Face (RF) provides an elevated sealing surface, improving gasket contact and enhancing the overall sealing capability, effectively preventing leaks in water supply systems. These flanges are typically crafted from materials like carbon steel, stainless steel, or other corrosion-resistant materials, ensuring durability and long-lasting performance in water transportation systems.

The ASME B16.5 Class 150 SORF Raised Face Slip-On Flange is predominantly used in water supply, irrigation, and wastewater management systems. Its simple installation process and robust sealing ability make it an excellent choice for both municipal and industrial water transport pipelines. When compared to traditional flanges, this design offers superior cost-effectiveness by reducing installation time and costs while maintaining a secure connection and long-term corrosion resistance. In summary, the ASME B16.5 Class 150 SORF Raised Face Slip-On Flange is an ideal solution for water supply systems, offering easy installation, strong sealing performance, and cost-effectiveness, making it perfect for applications requiring reliable water transport.

Understanding ASME B16.5: The ASME B16.5 standard defines the design, material, dimensions, pressure-temperature ratings, and testing requirements for pipe flanges and flanged fittings. Specifically, the "Class 150" designation refers to the flange's pressure rating, which is 150 pounds per square inch (psi) for standard temperature conditions. The ASME B16.5 standard ensures that flanges manufactured under its guidelines adhere to a high level of quality and performance for industrial use.

Titanium Gr1 and Gr2 Flanges: Titanium (Ti) is a highly valued material in various industries due to its exceptional corrosion resistance, light weight, and high strength-to-weight ratio. Titanium grades are classified based on their purity and mechanical properties, with Grade 1 (Gr1) being the most pure form and Grade 2 (Gr2) offering better strength, making it suitable for many applications.

• Grade 1 Titanium (Gr1): Gr1 titanium is commercially pure and has excellent resistance to corrosion in various environments, particularly in reducing acids and seawater. It is highly ductile and offers ease of fabrication, making it ideal for applications where corrosion resistance is the primary requirement.

• Grade 2 Titanium (Gr2): Gr2 titanium is slightly stronger than Grade 1 and is the most commonly used titanium alloy. It provides a good balance between strength and ductility while retaining outstanding corrosion resistance. This makes it perfect for industrial applications, including pipeline systems.

Slip-On Flange Design: A Slip-On flange is designed to slip over the pipe and is then welded in place, both inside and outside, to ensure a tight seal. This flange design is advantageous for several reasons:

1. Ease of Installation: Slip-On flanges are easy to install and require less machining, making them a cost-effective solution.
2. Versatility: These flanges are compatible with various pipe sizes and pressure classes, making them suitable for a wide range of applications.
3. Cost-Effective: Slip-On flanges are generally less expensive than other types of flanges due to their simpler design and ease of fabrication.

Raised Face (RF) Flange: The Raised Face (RF) is a feature of flanges designed to create a better seal. A raised face flange has a slight protrusion at the center of the flange that allows the gasket to be compressed evenly, resulting in a more secure and leak-proof connection. This feature is particularly important in high-pressure and high-temperature systems.

The Raised Face design is especially beneficial in industrial pipelines that experience fluctuating pressure, as it helps prevent leakage and enhances the overall integrity of the system. It is a commonly used flange design in industries where safety and performance are critical.

Applications of ASME B16.5 Class 150 Ti Gr1 and Gr2 Flanges: The ASME B16.5 Class 150 Titanium Gr1 and Gr2 Slip-On Raised Face Flanges are used in various industrial applications that demand corrosion resistance and high performance. Some of these applications include:

1. Chemical Processing: Titanium flanges are ideal for chemical plants that deal with corrosive chemicals and acids, as they are resistant to a wide range of harsh substances.
2. Marine and Offshore: Due to titanium's ability to withstand seawater corrosion, these flanges are widely used in marine and offshore pipeline systems.
3. Aerospace: The high strength-to-weight ratio of titanium makes it a preferred material for aerospace applications, where weight reduction is crucial.
4. Power Generation: Titanium flanges are commonly used in power plants, particularly in systems handling steam, gas, and other fluids under high pressure and temperature.

Key Features of ASME B16.5 Titanium Slip-On Flanges:

The ASME B16.5 Titanium Slip-On Flange is a high-performance pipe flange designed according to the ANSI/ASME B16.5 standard, commonly used in industrial applications that demand exceptional corrosion resistance and strength. Manufactured from titanium alloys such as Gr1, Gr2, or Gr5, this flange provides outstanding resistance to corrosion, particularly in challenging environments such as chemical processing, seawater, and high-temperature conditions. Gr1 and Gr2 are commercially pure titanium grades, ideal for environments where high corrosion resistance is required, while Gr5 is an alloy that offers increased strength for demanding applications that need more mechanical robustness.

The Slip-On design of this flange allows it to easily slide onto the pipe, with welds on both the inside and outside to ensure a secure, leak-free connection. This design simplifies installation, making it a favorable choice for low- and medium-pressure systems. The Raised Face (RF) configuration enhances the flange’s sealing surface, improving its ability to form a strong seal with gaskets and reducing the likelihood of leaks, even in high-pressure applications that require a tight seal.

ASME B16.5 Titanium Slip-On Flanges are available in various pressure ratings such as Class 150, 300, and 600, catering to different pressure requirements. For example, a Class 300 flange can handle up to 300 psi of pressure. The lightweight yet strong properties of titanium make these flanges ideal for applications where weight constraints are critical, such as in the aerospace or offshore oil and gas sectors.

Thanks to its superior corrosion resistance, the titanium flange is highly durable in harsh environments like seawater treatment, petrochemical processes, and pharmaceutical production. This durability extends the service life of equipment and reduces the frequency of maintenance and replacements. The flange’s excellent resistance to wear and high temperatures further ensures reliable performance, even under fluctuating temperature conditions.

One of the significant advantages of the ASME B16.5 Titanium Slip-On Flange is its ease of installation. The Slip-On design streamlines the installation process, particularly in tight or confined spaces where time and space constraints are a concern. Overall, the ASME B16.5 Titanium Slip-On Flange is highly valued across various industries for its corrosion resistance, high strength, excellent sealing performance, and ease of installation, making it the ideal choice for applications where durability and reliability are essential.
