Gr5 Gr7 Class 150 ASME B16.5 Titanium Flanges Slip On Flange Raised Face SORF for Piping Systems
DIN 86030 Titanium Hubbed Slip-On Flanges – Ti Gr 2, Gr 5, Gr 7
DIN 86030 titanium hubbed slip-on flanges, available in grades Ti Gr 2, Gr 5, and Gr 7, are designed to meet the rigorous demands of various industrial applications. These flanges are widely used in industries where corrosion resistance, high strength, and lightweight materials are critical, such as in the chemical, aerospace, and marine sectors. The design and materials used in these flanges offer durability and reliability, ensuring safe and efficient connections in pipe systems operating under challenging conditions.
The hubbed slip-on flanges conform to the DIN 86030 standard, which ensures high-quality manufacturing and precise specifications. These flanges feature a raised face (RF) or flat face (FF), both of which are designed to enhance the sealing capabilities when paired with gaskets. The hubbed design allows for a smooth connection to the pipe, providing strength and stability while also facilitating easier welding. The use of titanium alloys, specifically Ti Gr 2 (pure titanium), Gr 5 (Ti-6Al-4V), and Gr 7 (Ti-0.15Pd), gives these flanges superior corrosion resistance, particularly in environments that involve exposure to aggressive chemicals, high temperatures, or marine conditions.
| Titanium Grade | Main Composition | Strength | Corrosion Resistance | Main Applications | Other Features |
|---|---|---|---|---|---|
| Ti Gr 2 | Pure Titanium (99.2% Ti) | Medium Strength | Excellent | Chemical, Marine, Medical | Excellent weldability and formability |
| Ti Gr 5 | Titanium-Aluminum-Vanadium (Ti-6Al-4V) | High Strength | Good | Aerospace, Automotive, Military | High strength with low density, suitable for high-temperature environments |
| Ti Gr 7 | Titanium-Palladium Alloy (Ti-0.15Pd) | Medium Strength | Excellent | Chemical, Marine, Petroleum | Outstanding resistance to sulfuric acid and chlorides |
Titanium hubbed slip-on flanges are versatile and can be used in a variety of settings where traditional carbon steel or stainless steel flanges might be less effective due to corrosion or weight concerns. In the aerospace industry, these flanges are used in aircraft fuel systems and other critical applications that require lightweight yet strong components. The chemical processing industry also benefits from these flanges, as the titanium alloys used can withstand harsh chemicals, high pressures, and elevated temperatures. Marine applications, such as in seawater desalination plants and offshore oil rigs, frequently use these flanges due to their exceptional resistance to saltwater corrosion.
Additionally, these titanium flanges are suitable for high-performance systems in power plants and other energy production facilities where equipment must endure extreme conditions without risk of failure. Their ability to resist corrosion from fluids and gases in industries like petrochemicals and pharmaceuticals makes them indispensable in ensuring the longevity and safety of piping systems.
| Titanium Grade | Size Range | Pressure Class | Temperature Range | Corrosion Resistance Standard | Main Applications |
|---|---|---|---|---|---|
| Ti Gr 2 | 1" - 24" | PN 10/16/25 | -200°C to 500°C | Suitable for most corrosion environments | Chemical, Marine Equipment |
| Ti Gr 5 | 1" - 36" | PN 10/16/40 | -250°C to 550°C | Suitable for high-temperature corrosion environments | Aerospace, Automotive, Energy Industry |
| Ti Gr 7 | 1" - 48" | PN 10/16/25 | -200°C to 450°C | Excellent acid resistance | Petroleum, Chemical, Marine Engineering |
The production of DIN 86030 titanium hubbed slip-on flanges involves several critical steps to ensure the highest quality. The process begins with the selection of high-grade titanium alloys, which are sourced from reputable suppliers. The material is then subjected to precision machining techniques to create the desired flange dimensions, ensuring that each piece meets the stringent tolerances set by the DIN 86030 standard.
After machining, the flanges undergo heat treatment to improve their mechanical properties and relieve any stresses induced during the machining process. This step is especially important for titanium Gr 5, which requires precise heat treatment to achieve optimal strength. Surface finishing is also an essential part of the production process, with options for anodizing or pickling to enhance corrosion resistance and improve the overall appearance of the flanges.
Once the titanium flanges are complete, they undergo rigorous quality control checks, including dimensional inspections and testing for material integrity. This ensures that each flange is ready for use in high-pressure, high-temperature, or highly corrosive environments.
DIN 86030 titanium hubbed slip-on flanges, made from Ti Gr 2, Gr 5, and Gr 7 alloys, are integral components in industries requiring superior strength, corrosion resistance, and lightweight performance. Their versatility, combined with advanced manufacturing techniques, ensures reliable performance in demanding applications, whether in aerospace, chemical processing, or marine environments. By choosing titanium flanges, companies can extend the lifespan of their piping systems, reduce maintenance costs, and improve overall system efficiency.
